Which head gasket is best for a Subaru?
If you’re finally going to have your head gaskets done on your Subaru it’s only smart to choose the best possible gasket available at that time . For a while the only option was a genuine Subaru gasket. Now we offer a solution that is arguably better than anything Subaru currently has to offer for the phase 2 2.5 engine. Plus you’ll no longer be required to install the Subaru Coolant Additive to your cooling system. Stay tuned for more detail as I add to this blog or stop by in person for more info.

Six-Star® Head gaskets are a multi-layer stainless steel head gasket engineered to insure years of longevity for your Subaru.
We believe so strongly in these gaskets that we exclusively use Six-Star® brand head gaskets on all of the phase1 and phase2 2.5 engines we repair at Smart Service.
We all know that a head gasket issue can be one of the biggest headaches you’ll ever run into on your Subaru. We only use Six-Star® gaskets at Smart Service when we perform a head gasket repair because we want it to be the final time you ever have to replace your head gaskets.
In our opinion, they are currently the best gasket available for the repair.
In comparison to the original single layer head gaskets your Subaru originally was equipped with, these head gaskets are comprised of three layers of stainless steel. Stainless steel is used for added strength, it’s ability to rebound, and it’s natural resistance to corrosion. They are constructed of 3 layers. The inner core is a layer of flat stainless steel sandwiched between and riveted to 2 layers of .010 embossed stainless with a flouroelastomer Viton coating.
The Viton rubber coating is one of Dupont’s high performance elastomers. In technical terms, Viton flouroelastomer rubber based material will easily handle temperatures from -40° to over 400ºF with the ability to withstand temperatures up to over 700°F for short periods.
The composition of these gaskets along with the interlocking embossments create unsurpassed sealing properties making Six-Star® Head Gaskets the ultimate choice for your all aluminum Subaru engine.
No More Coolant Additive!
The unique design and properties of the multi-layered stainless steel gasket combined with superior ability of the Viton coating to withstand heat, chemicals and corrosion, it may be last head gasket replacement you’ll ever need for your Subaru engine. Not to mention, you’ll never need to use the Subaru Coolant Additive ever again on your engine.
Hello Mile Thank you for your information I actually need to replace a headgasket on my 2001 Subaru Outback. I took it for a recall on the cooling system but on 04/16/04 at Peninsula Subary, Bremerton WA but they never told me about the head gasket.
Mike-
My wife’s 2003 Outback 2.5L built in Dec. of 2002 was recently diagnosed with leaking head gaskets (both sides are leaking oil and at least one side (left) is leaking coolant). And supposedly it is also leaking power steering fluid from the “input shaft”.
I have a two part question, the first is whether or not this car would possibly be included in the Subaru recall for leaking head gaskets?
And the second question is that I was planning on doing the fix for this car with a friend of mine who is a mechanic. Could you tell me what manufacturer made this gasket that you pictured? And where do I get it?
Will these head gaskets work on 96 – 99 Legacy and or Outback. Why the range of years, I,ll be buying one soon, and chances are I,ll be changing gaskets. Thanks
The Subaru dealer I bought my 99 Forester from maintain my car since then. 3 yrs ago (at 70,000 miles) they said head gasket leaked and changed both gaskets, which I paid for. I was never notified any recalls about it or not told to use special coolent after replacement. Now 30 thousand miles later, I am just told (during a routine minor maintenance check at 93,000 miles)head gasket is leaking and I need to pay for it. I did not accept to pay for it, but 3 weeks later, my car is still with the dealer and I am using their loaner car. They are not able to come with a solution yet. Tomorrow, I am going to the dealer to talk it out and I want to thank you for the information. It will help me to discuss the issue with them. If you can comment about my situation, I also will appreciate it. I always had a very good relationship with them and that is probably making it difficult for them to say no, but I do not think I should pay for a new head gasket and $2800 every 30,000 miles. If I was notified about the problem then, I would prefer to sell the car after the first incident.
I am about to do my head gaskets for the second time on my 2000 outback(150,000). I would like to know why it is better, who makes this gasket and where can I get them.
Thanks

My son has a 2002 subaru legacy GT–how do I tell if it is a phase 2 2.5? I have a feeling that we have a gasket leak as we loose coolant over time, but it must be very slight. I am just wondering if this car is worth haveing an expensive repair like this done or not. We just put $400 into it to have both the O2 sensors replaced and the check engine has just come on again, which our mechanic claims would likely mean the cat is shot. He really loves this car and I have to admit its a nice ride, I just want make sure we’re just wasting our time and money
Hello,
I’m unable to tell you if Subaru will participate in the repairs of your head gaskets but I would certainly call their 1-800-SUBARU-3 customer service hotline to discuss it with them.
As far as the head gasket, they are “Six Star” brand by Northeast Imported parts. We do sell them here and you can call us to order a set if you would like.
Thank you,
Mike
We have the same gasket to fit the 1996-1999 2.5L engine. The best option for the 2.2 equipped Subarus is still the genuine Subaru head gasket.
Cheers,
Mike
I sympathize with your frustration. That is the reason that we went with an alternative Subaru head gasket. We just saw enough repeat failures that we believed there must be something better out there.
I understand the difficult position the Subaru dealer must be in. They want to keep your loyalty but it may be expensive for them to keep it. I hope they decide to help you.
Take care,
Mike
Hi Jeff, We have them in stock if you’d like to order a pair. Northeast Imported makes the “Six Star” gasket.
Mike
All 2002 GT’s were phase 2 2.5 engines. I am of the opinion that fixing the car is worthwhile if it is in otherwise good condition.
I believe that if you crunch the numbers it will be obvious that repairing the car (assuming you like it) will leave you much further ahead monetarily than trading it in on a new one. You compare $3000 bill on a repair to a car you own that will probably last the next 5 to 10 years vs. $3000 down payment plus $600 per month payments for 5 years.
In most cases the most costly repairs will be behind you once the head gaskets are done. Then just normal wear and tear, tune up expenses etc that you’d still have to do even on a new car.
I hope this helps.
Mike
Mike,
I can’t believe I’m reading this! I’ve been battling a “4th cylinder misfire” for the last 2 years. In addition, the engine coolant levels have been dropping, bit by bit, but with nothing showing on the ground. My mechanic just said, “maybe there is a slow leak around the head gasket, which would also explain the misfire”.
Who knew?
I bought the car second hand. It’s got 192,000 miles on it. Probably not worth a new head gasket at this point.
Oh, well.
Kim
Yes we do,
You can call us to order a pair at 206-417-0880
Mike
hey mike
thanks for the information. am considering buying my first subaru, i live in new hampshire and it seems the logical choice. i have been inquiring around and am hearing, from sellers of subarus, that the head gasket issues were taken care of in the 2005 models and later. is this your experience? if i went with an earlier model and the head gasket goes is it a $3000 repair? is it cheaper if you replace the gasket as prevention even if its not going? are some models better than others – although they all have basically the same engine, yes? ill keep researching this stuff myself too…
and kim…dont know what model you have or if this effects you – i have been looking into the catalytic converter problems on subies too and thought of your misfire when i saw this on http://www.cars101.com/recalls.html from 10/09 – is this reliable information, mike?
“Certain 2005-2008 Forester and 2005~2007 Impreza models require permanent removal of the one-way fuel valve located in the fuel tank. The valve is in a sub-chamber in the fuel tank and when the tank’s fuel level drops below 1½ gallons, the sub-chamber is intended to provide a reserve for the fuel pump during vehicle cornering. However, the one-way valve may inadvertently act in such a way as to prevent fuel from refilling the sub-chamber, failing to provide the intended reserve. If this were to happen, the fuel pump could momentarily draw air causing the engine to experience a sporadic misfire condition resulting in possible damage to the vehicle’s catalytic converter. (The “Check Engine” light will illuminate alerting the driver that the catalytic converter efficiency has degraded beyond an acceptable level and may be releasing air pollutants that exceed emission standards.) This Service Program will remove the valve. Program #WVL-22″
I have a 2001 Subaru Forester and have been told there had been a recall due to a failed head gasket. Because I bought this car used I did not receive this recall. What can I do to get this fixed. I have been experiencing problems with this. If I have to pay for it what will it cost me?
Hi Mike, thank you, your a good guy… great info..
I have a 2001 Forester I bought used in 2005 that was “Brand New” it still smelled new inside with only 4 thousand miles on it. (senior couple owned it).
Now in 2010 I have 54K miles on it and my story with it over heating will sound like everyone else that has this over heating problem.
I’ve taken very good care of this car being I’m an x mechanic knowing how important maintenance is to a car.
When the temp is in the mid to low 90′s the car is fine in heavy traffic, the temp needs to reach to 98 degrees before the temp gauge starts to act up towards over heating. I never made it to over heating because I’ll shut down very fast.
I wanted to ask you Mike, has this new stainless steel head gasket been used in another engine application? perhaps for other reasons as if a marine engine that uses ocean water to cool the engines? or maybe even another similar vehicle problem.
Before not knowing that the deal was I thought it was a poor design in air flow in hot weather, so I was going to add a third or a bigger fan with a manual over ride switch to use at will. I’ve seen that done on custom rods and you can actually watch the temp gauge go right down…
But as this head gasket gets worse I suppose I’ll be fighting a loosing battle in time.
I have a 2000 Outback wagon with 141,000 miles that needs a new head gasket. I am told I should also replace water pump and timing belt and should expect to pay about $2,500. I am trying to decide if I should fix or trade it in for a 2001 or newer model with less miles. The car will soon be paid off. A NOC senosr and front CV joints have recently been replaced and oil has been changed regularly. Transmission seems fine but is that next? Any advice on the “fix or buy” question? Thanks!
I should add that I discovered it running really hot one day and had to drive several miles before I could get off the freeway and get some more coolant in the radiator. What are the chances I have done serious damage to the engine? I took it to Walker Subaru and they of course are interested in selling me a car. They said they will take mine with its problems and sell me a 2001 with 87,000 miles for nothing down and $250 -300 month for 36 months.
We see that the newer the Subaru, the fewer the frequency of head gasket of failure. I agree with you that 2005 and newer seems to be slim to nil failure rate. We haven’t seen any issues with the 05 head gaskets and newer yet at our shop. I have heard of a couple 05 failures from my friend at a local Subaru dealer.
If you went with an earlier model, mentally keeping $2500 set aside for a future repair would be prudent. I’m not a believer in replacing head gaskets that are not leaking just as preventive maintenance but, if there are other looming repairs such as engine oil leaks, timing belt needs that would be costing 2/3 or more of the full head gasket expense, it may be best to just get it done then.
Good luck with your Subaru purchase. I’m sure once you’ve done your research and chosen the Subaru that best fits your needs you’ll be a Subaru owner for life.
Take care,
Mike
I think before making any changes you have to confirm what the actual issue with your Subaru is.
If the car is running near the red because of failing head gaskets (either loosing coolant externally or having exhaust gasses pushed past the head gaskets into the cooling system) adding another fan will be a waste of time.
If your head gaskets, thermostat etc. are in good mechanical condition, the fans are coming on when they should etc. I would check to see if you may have a restricted radiator (either internally or externally-bugs dirt).
The multi layer steel gasket we offer for your Subaru is a style of gasket that’s been used in the automotive industry for quite a few years now. The design and materials are what set the quality gasket apart from the average gasket. The same company that designed and manufactures the Six Star head gasket also designs and manufactures head gaskets for NASCAR and other racing applications so they have lots of experience dealing with extreme conditions. I do not know if they are used in marine applications.

Whether or not this particular dealer action affects your particular Subaru is something I can’t answer without your VIN but the WVL-22 Subaru Recall Notice is a valid recall.
I advise you to call your local Subaru dealer service department with your vehicle VIN # and ask them if there are any open campaigns or recalls on your vehicle. I also advise any Subaru owner to do this from time to time since mail intended to notify you of recalls or campaigns may not always get to you.
Happy motoring,

I think your price point for the repair is in the ballpark as far as complete Subaru head gasket jobs go. If it’s done for much less then there are probably corners being cut.
The decision to fix or trade in depends on the condition of your car and if you’d like to make car payments for the next 3 years on a Subaru that will eventually come up with the same problem in my opininon.
If your 2000 Outback is in reasonably good condition and has been properly maintained than you’ll be much further ahead monetarily to repair it. (If I had it done I would recommend using the Six Star gaskets so you won’t have to do it again in the future). The fact you overheated it may or may not have an affect on the repair price. If it overheated enough to damage the block you would then be closer to the $4500 price range for the whole repair since it may necessitate replacing the short block. If it was disassembeled and the engine block was found to be warped, we do have an in-house method of repairing it if it’s not too far beyond factory specs.
$2500 can be paid of in 8 months at $300 a month. (most probable scenario)
$4500 can be paid off at $300 per month in 15 months. (worse case scenario)
2001 Subaru… 36 months and it will likely still need head gaskets in it’s future based on what we’ve seen so you can add another $2500 in future expenses to that one along with usual wear and tear expenses.
I hope this helps you come to a decision that works out best for you and your Subaru

I believe the 3.0 H6 cyl has better chance to survive this head gasket problems than the 2.5
Raphael, Although there are far fewer H6 equipped Subarus out there, they have now been around since 2002 and between both of our Subaru shops we have only seen a couple of failures. I believe if we were to compile statistics, the H6 would have an extrordinarily lower head gasket failure rate than the 2.5 equipped Subarus that are out there. We’ve seen a similar quality on the WRX Turbo 2.0 and 2.5 engines. They seem to have a significantly lower failure rate on their head gaskets also. Maybe another good topic in the works…..

Mike,
I just stumbled upon this site. I own a 2004 Legacy Outback 4EAT that I bought 2nd hand in Jan 2006. It had about 60,000 miles on it and now has 100,000. I took it into the dealership 6 months ago and they told me it had the head gasket leaking and that it would cost me $3,500 to repair. I took it to another mechanic for a 2nd opinion and he said I should call Subaru North America and insist they cover it under WWP-99…despite the fact that only cars thru 2002 were covered under that recall. He also told me this “conditioner” they instruct everyone to put into the engine is just a gimmick…just particle filled liquid to prevent the leak. What do you think?
Hi Jonathan,
Here’s a link to another blog that goes into more detail on how you might approach it:
http://www.smart-service.com/blog/2010/02/subaru-head-gasket-will-subaru-pay-for-repair
I believe it’s worth calling Subaru at 1-800-SUBARU3 customer service to explain your situation.
As far as the “conditioner” being a gimmick… I don’t believe it’s a gimmick but an attempt at a more cost effective way of reducing the number of head gasket leaks on this particular engine(thus reducing possible damage to their reputation). It may serve to fix or minimize the symptom but may not address the cause. Subaru doesn’t have the same deep pockets as Toyota and I believe it’s unlikely we’ll see any kind across the board head gasket replacement recall. I could be wrong but I doubt it. Especially in a situation where a majority of the failures are occuring beyond the 5 year 60000 mile warranty provided by Subaru when a person purchased the car.
Good luck with Subaru corporate!

I own two 2003 subaru foresters and both are having head gasket issues. The one had a complete failure in February of this year after noticeable leakage for 3 years. There was a severe internal leakage as well which I feel has been responsible for poisoning the oxygen sensors and cat. So after a $2800 gasket repair I need a $1600 cat repair. The second forester with half the mileage is currently starting to leak as well and it has started throwing cat efficiency errors as well now. Very disappointing. I’ve recommended subaru to several friends over the years and they have purchased outbacks and foresters. Can’t say I’m confident in recommending them anymore as the service costs are comparable to poorly designed North American vehicles. Gave my son the repaired sube, my wife is slowly destroying the other sube and I’m now driving a honda civic. (my first ’89 civic lasted 12 years before it was totaled by a hit from behind and I spent less than $3500 total to maintain it for those 12 years. In fact, this contributed to my decision to buy a Japanese built subaru… how ironic!)
I’m sorry to hear of your woes. I think most Subaru entheusiasts are in the same boat as you and I in saying that we’re all very disappointed by the amount of head gasket failures we’ve seen thus far. I also agree with your opinion that the coolant over time may have lead to the failure of the catalytic converter and O2 sensor.
I hope someday Subaru is able to redeem your confidence in their product. We really love what they offer and there still isn’t a better designed AWD system in existence in my opinion.

I am looking at buying a 2003 Outback that appears to be in excellent condition with just over 32,000 miles. Is there a web site I can go to that with the vin number, or prior owner information can find out if the recalls were taken care of?
For information on title, mileage and recalls on your Subaru I would purchase a Carfax report (www.carfax.com). I would follow it up with a call to the dealer with the VIN # and request if there are any completed or outstanding recalls.
I would also avoid any Subaru that shows a “rebuilt” or “salvage” title.
Last but not least, make sure you have a Subaru specific shop inspect it before you sign on the bottom line.

Hi
I am looking at purchasing a 2006 Impreza should I be worried about a head gasket leak in the future?
Thanks
Elise
My ’03 Forester @ 90,000 miles was doing hilly commutes 54 miles round trip for 2 years here in NJ at which point overheating on thermostat dial started occurring. My Sube mechanic topped off the coolant, replaced thermosstat & did the timing belt 2 years ago. This month in city stop & go traffic, the car overheated again. This worked for awhile. @ 126,000 miles, after numerous opinion, mechanics chemically analysed the coolant & found positive hydrocarbans, meaning oil leaking secondary to gasket leakin. When engine revved up, saw bubbles in the coolant reservoir. Just spent $1900 on mechanic labor to replace gaskets. Time to trade?
Hi George,
I think it may be a worthy investment to have the head gaskets replaced on your Forester if the rest of it is in overall good condition. Subarus frequently go 200,000 miles plus once the head gasket issue has been taken care of. Let’s say you spend $1900 on the head gaskets and another $500 on misc. other repair/maintenance that might make sense to do while the car is being worked on. You compare that to the diminished trade in value the car has in the condition it’s in along with what you would have to come up with for a down payment to replace the car and it’s a no brainer (espescially when you consider the car payment you will be avoiding).
Now, if budget is not an issue and you just would like to own a newer Subaru that better fits your needs, it may be a reasonable time to part ways with your Subie.
Good luck on your decision what ever it may be,
Mike Corbin

Hi Elise,
I wouldn’t be too concerned with head gaskets on a 2006 Impreza. We have seen very few of them fail and they seem to be holding up better than the prior model year Subarus. As with any Subaru, I recommend having it fully inspected by a reputable shop before making the purchase.

Just stumbled across you blog while doing a search on Subaru head gasket problems. I have a 2002 Subaru Outback Sport with 172K. Last night driving home from work, the radiator overheated, the reserve cap blew spewing this yellow mustard colored liquid all over the interior of my engine compartment. Yup…the head gaskets blew. And I’m not sure why the coolant was so dirty. Was not aware of the head gasket issues prior to this. Looks like I’m in for the full expensive repair, but going to call the Subaru customer service hotline with high hopes. Just wondering if anyone has had problems with Subaru service centers refusing to put in non Subaru genuine parts as the Six Star Headgaskets seems to be the way to go.
Sorry to hear the news C.J.
If Subaru does opt to help you out, I’m sure they’ll only use their own gaskets since it’s the only way they would be able to warranty the work on the head gaskets. It’s the same most places you would go. If a shop can’t use what it feels is best for the job they may opt to do it but they won’t stand behind it.
Good luck,

I have a 2001 Subaru Forester, received the recall a few months after buying the car. Took it in to be addressed by Subaru dealer. Always kept up on all the required maintenance. Now 9 years later and out of warranty the head gaskets leak and had to be replaced, which I paid a pretty penny for Subaru to do. Today while talking to a friend that is a certified Subaru mechanic he gave me some interesting information regarding this recall. In order to avoid eating the costs of replacing head gaskets under warranty, Subaru came up with this additive which contains some pulpy stuff that would stop a leak should one develop in order to stall the inevitable need to have the head gaskets replaced, hoping that this would happen out of warranty so the customer would have to foot the bill. This is a bit underhanded to me. Do you know if I would have any recourse to get some kind of reimbursement for that head gasket job?
Hi Susan,
To the best of my knowledge, if your Forester was included in the recall in which they added Subaru Coolant Additive to the cooling system in order to prevent the head gaskets from leaking it also gave you an extended head gasket warranty for 8 years or 100000 miles (whichever came first) on external coolant leaks from the head gaskets. If there is a chance Subaru will help with the cost of the head gaskets, it is usually decided before the job is done. Since you’ve already paid for the job it may be more difficult to get financial help. I would still call 1-800-SUBARU3 and explain your situation to see if they may elect to help you. It’s worth a try at least.
Good luck,

Hello Mr. Corbin:
I’m happy to report that I was able to get some compensation from Subaru. It came to 50% of the work for the head gasket. I’m pleased with the settlement as I paid a lot to get that repaired and 50% is better than 0%. It’s nice to know that Subaru does work with its customers even when the vehicle is out of warranty.
Thank you for your blog!
Susan, that’s great!
If there’s any other helpful information on how you got them to participate in helping you, please feel free to post it. It may help someone else in a similar situation.

I picked up an 02 Impreza 2.5 SOHC. I noticed a coolant leak on the back of the Driver’s side head(uv dye helped). I noticed oil leaking too, so I bought some UV dye for the oil and discovered the bottom of the head was also leaking oil. I don’t know what the series cut off points are, but am curious if these gaskets cover my car? It is an early 02 build, and EJ251 is the engine number on the dataplate.
Hello Mr. Corbin:
I went to their website Subaru.com then went to the bottom of the page and saw “Contact Us”. I’ve used this form in the past when I wrote them about how well my Subee performed after a trip I took. Anyway, I filled out the form and almost word for word what I wrote to you is what I wrote to Subaru. Based on my experience Subaru is a decent company they want customer loyalty so they’re willing to work with their customers. Apparently their policy is 50% when out of warranty. Don’t know if I would have gotten more or nothing at all if I pressed my issue.
The main thing is: Keep to the facts about the issue and be able to back it up with a dealers work order. They will want copies of the work order in question. It contains a wealth of information that they’re looking for to make their decision. They don’t answer e-mails right away, usually takes a day for a response, so be patient.
This whole process was resolved in less than a week because of e-mail and a scanner. I should get the check in 2 weeks.
Thanks again!
Hi Mike,
Original owner of a 2001 Forester with 150k on the clock. Started smelling sweet a few months ago. My (former) mechanic couldn’t diagnose it. My new one did; externally leaking head gasket. Never has overheated. I confirmed that the SB WW99 was applied (in 2005 at 74k miles). I never got a notice to have the conditioner replaced at each 30k coolant interval recommended in the manual. So, I probably didn’t get that from my various mechanics.
Would adding the conditioner now seal the leak?
When I called Subaru NA, at 800.SUB.ARU3, they listened to my sad tale and declined to assist in the repair. I absolutely want to know what Susan did to get some help! They only would offer me a $750 rebate on a new car. 150k is normal performance these days. My Mazda Protege started dropping body parts at 160k, but motor was going strong. Wife’s 1990 Camry was traded in at 160k for the Forester. NOTHING was wrong with it.
I’m mostly convinced by your repair arguments above. Any suggestions as to what all to do to it while heads are off? Can I make it more fun to drive without getting crazy?
Timing belt and water pump are ones I’m planning already, but those won’t add fun.
This car also burns up tires. Mechanic told me alignment is not adjustable.
This is quite a helpful resource, thank you.
I am in the market for a Forester. I have a couple of 2001s and 1999s in mind. All with 112,00-130,00 miles on them. We are on a budget of $4500 and was wondering what may be the best choice based on years? We definitely do not have $2500 to spend on head gaskets….
Thanks!
Thanks for the info. I hope it’s helpful for other head gasket suffering Subaru owners.
Mike
Hi,
They really are pretty much identical vehicles, engine, trans etc. There is no one year in that range that is better than another.
I would just pick the one with the prooves best upon mechanical inspection.
If one of the 4 has already had head gaskets completed recently it may be the best option as long as they were either done with Six Star or Genuine Subaru head gaskets.
It think your budget of $4500 will give you a reasonable selection to choose from.
Good luck and make sure you have it inspected before making the purchase. If anyone is too busy etc to let you do an inspection, walk away.
Good luck!

Hi Kris,
I posted Susan’s reply today on what worked for her. Sorry Subaru has declined to help you thus far.
As far as making any fun improvements while it’s apart, there isn’t too much you can do at this without thousands of dollars. By the way, Subaru alignment is fully adjustable front and rear on Subaru Foresters so you might take it to a different mechanic.

Thanks Mike.
Do you recommend using new head bolts when doing the head gaskets?
I have a 2002 Forester with the 2 phase 2.5 engine, 79K miles, that has been diagnosed with external head gasket failure. I got the recall notice and conditioner was added at about 17K miles, and at 30K service, but not at 60K service at an independant. After talking to SOA, they offered $500 toward service. The dealership quotes warranty price of $1,200. If I add in the timing belt and water pump, it brings the gross price to about $1,500, or a cost to me of about $1,000. The dealership says they will pull the engine. I’ve been quoted a price for all that of about $2,200 at a very reputable nearby shop that will use the Six-star gaskets. What do I do? Is it worth the $1,000 to $1,200 extra for a Six-Star gasket? If I buy the Six-Star and take it to the dealer will they install it? Are the replacement Subaru gaskets better than the original? Is the job performed at the dealer likely to be decent?
Hi Tim,
I’m glad to hear Subaru is offering to do at least something for you.
If you’re going to keep the car long term (which I would think make sense on a Forester with only 79k) I would opt for the full package with the Six Star head gaskets.
The dealer is probably only going to replace 1 head gasket in their repair and eventually you will need to do the other side anyway. I do believe that the genuine Subaru head gasket that is being used now is much more reliable than the one that was originally in there.
I don’t think the dealer will use anything other than genuine Subaru parts since Subaru is participating in the repair.
Bottom line, if it’s a nice Subaru that you would be happy to drive the next 5 or more years I think it would be a sensible investment to have the engine pulled, have both gaskets replaced along with the other seals and gaskets relating to the job. Just make sure the shop you are having it performed at makes sure that the cylinder heads and engine block surfaces are perfect and have a RA finish of 50 or higher (machine shop term for roughness average).
Feel free to call me if you need any more advice.

Great question Ryan.
This is an interesting topic. Subaru does not specify anywhere that their head bolts must be replaced if they are removed. On the other hand, Six Star recommends replacing them with their new head gaskets.
In my opinion, if making head gaskets last were as easy as just using new head bolts when doing the job, Subaru would have recommended it a long time ago. Since they don’t recommend it I think that says alot about there opinion on the imortance of the head bolt in the whole formula.
I think replacing the head bolts is an outstand precaution that eliminates the possibility that the old bolts are somehow stretched or flawed but I don’t think it is a requirement.
I don’t have hard numbers on this one but in general I haven’t seen any higher failure rate of head gaskets on vehicles that did not use new bolts vs. vehicles that used new. The biggest reason we’ve seen cars that come in to have their second set of head gaskets replaced is that there were imperfections in the cylinder head and or block upon assembly that kept the head gasket from sealing as well as it could have.
Good luck,

Hey Mike, I just purchased a 97 legacy with the 2.5 with 117 k on it. The owners told me that the head gasket, water pump, and radiator were just changed about 5k ago. They gave me the reciepts for proof. Just recently my subbie has developed a knocking noise. I am hoping it is not a rod or rod bearing. Could anything have been done to develop this when the gasket was installed? Do you have any suggestions on what I could check that would tell me if there is a bad rod or rod bearing? Would checking oil pressrue tell me? Could it be a knock sensor? Timing belt pully? How can I decifer what this sound is?
Hi Chad,
I’m sorry to hear about the issue with your Subaru Legacy.
I don’t believe that anything during the repair would have caused the knock unless the car was just plain started and run without oil.
To check for a bad rod bearing, remove each fuel injector connector one at a time while the engine is running and the noise is evident. If the sound goes away or diminishes significantly then you’ve found your cylinder.
Also, there can be a knocking noise on a Subaru 2.5 that relates to some slack in the hydraulic tensioner ram that keeps tension on the timing belt. It usually will be in the front/center of the engine only on startup after sitting overnight. It is best to have the timing covers off when listening for this one with an automotive stethescope.
Good luck,

I stumbled across this site in my search of info about failed head gaskets. I have a 2002 Subaru Legacy which started having problems at 56k. Based on what I found here and elsewhere I called various dealership to find out if there were any outstanding recalls on my Subaru, which they claimed there weren’t (but I had already read there were). To repair the head gaskets I was given quotes ranging from $2,000 to $3,000.
To make a long story short, I called various dealers. Of them, only one said there was a known head gasket problem. He further volunteered the following info: Subaru will pay in full to have the head gaskets replaced if you are the original owner of the vehicle and can show you performed the first major maintenance at 30,000 (I think it needs to be w/ a dealer but if you have records to show you did it elsewhere, I’d definitely try to get reimbursement from them!). I know others have gotten partial reimbursement from SOA but try to find a dealer to go through and see if he can get you full reimbursement, which this guy did for me. Obviously I’m going to throw some business his way in the future, so we both wind up winning.
Anyway, hope this helps others.
Very nice.
I’m pleased to hear any time that Subaru will step up and fix the head gaskets at no charge to you. Once again, it pays to do your homework and be persistent. I’m disappointed that the other Subaru dealers you approached didn’t at least acknowledge the head gasket problem.
I hope your experience is helpful for others out there trying to get help from Subaru on their head gaskets.

Hello,
I own Subaru Legacy 2003 2.5L and am the first owner and am being Canadian. Unfortunately none of the above are supposedly refer to the Canadian clientele and owners of Subaru cars.
I stumbled across this site,too, to look for more info about these leaking head gaskets. The mileage in our Subaru is close to 146K but still, didn’t expect to have any problems so early with my car.
I am afraid that I will have to replace head gaskets on both sides, because I am loosing coolant quite a lot.
I would want to know if there is a slight chance to get partly reimbursed by Subaru Canada? Anyone knows?
It will be of great help knowing that there is such a possibility.
Thanks a lot for your help,
cheers,
Alex.
Hi Alex,
Not sure what Subaru of Canada’s policies are with warranty repairs but the good thing going for you is your low mileage (146k kilometers? about 90k miles). The campaign/recall in the United States stipulated that if the coolant additive recall was performed that Subaru of America would warranty the head gaskets for coolant leakage for 8yrs or 100000 miles, whicever came first. I would start by calling your local Subaru dealer to see if they can help. If not call your nationwide Subaru customer service number. I hope you have luck with Subaru of Canada and some help in replacing those head gaskets on the 2.5.
Good luck,

Mike,
Nice blog here…hoping you can help. I recently did an engine rebuild and used Six Star MLS gaskets. I had to remove a head after the head bolts have been torqued (engine was not even cranked over – still a long block). Can these gaskets be reused in this case?
Thanks!
Hi Mike, I just found this site while searching for failed head gasket information. Noone seems to be too sure what is wrong with my car. I have a 1999 Subaru Legacy Outback wagon with 2.5l turbo and 196,000kms. I bought this car 1 year ago from the original owner. Since overheating the first time in August, I noticed that my reserve tank from the radiator was quite dirty and realized the second time(November)it was in fact oil, however, there is no evidence of oil in the radiator.How would it get to the reserve tank? The car has overheated 4 specific times. The last time being this past Friday, and the weather certainly wasn’t warm here in New Brunswick!(The car is parked for now.) Once the car is stopped, it heats right up and blows radiator fluid out the purge hole from the reserve tank. I don’t seem to be leaking any fluid. Should I bother with the thermostat? Or, once the repair is begun, how probable is it that the heads will be warped? Also, does the six star gasket fit my model? Thanks for the information. ( As well, I was just about to have the gas tank replaced, should I bother?) Kelli
Hi Nick,
I would not recommend using the Six Star head gasket after it has already been torqued (nor any coated MLS gasket for that matter). The sealing surface may have been compromised as well as the raised embossments. For the price it’s cheap insurance just to use a new one.
Take Care,

Hi Kelli,
It is probable that the oil in your recovery tank is from the radiator and cooling system. Remember the oil always floats to the top. You’ll also probably find your radiator cap seal is swollen from being in contact with the HC’s. (hydrocarbons). I wouldn’t waste time with your thermostat. If you’re gushing coolant is is probable that there is a significant failure of the gasket forcing combustion in the cooling system and forcing coolant out. A quick sniff with an exhaust gas analyzer will probably show high amounts of hydrocarbons in the system.
We do sell Six Star gaskets for that engine. From the sounds of it yours may be more severe and I wouldn’t be surprised if the heads and block are warped beyond specs.
It’s a bummer but from your info that’s my best guess without seeing it.
Good luck,

Hi Mike,
the Subaru recalls website had a link to your site. We have a 2002 Forester which needs new gaskets. We have just over 100,000 miles on it. We never received anything from Subaru about recalls before, or what to do to prevent problems. We’re taking it into the dealer on Saturday for them to look at it. Any chance, do you think, they’ll cover the repair costs?
Thanks,
Sara
Hi Sara,
From other postings I do think you have a fair chance of Subaru at least helping out with the head gaskets. I could be wrong. It’s possible that they’ll bring up the fact that it never had the recall and opt out of helping. You never know. It may come down to your relationship with the dealer that it’s at.
Good luck and let us know how it turns out.

Hi Mike,
Great blog – and I apologize if my question was answered in here somewhere and I missed it but….I actually had the head gaskets in my 2001 Legacy replaced in 2004. My dealer said it was a recall issue and fixed it at no cost. Apparently I have a head gasket issue again now.(115K miles total) That doesn’t seem right – is it?
I’ll put a call in to Subaru but also if you think replacement is a realistic possibility, do you have a recommendation for a service center in Denver?
Thanks,
Nancy
Hi Nancy, Sorry to the head gaskets done by the Subaru dealer may not have held up. I know it doesn’t seem right that the head gaskets have failed again but depending on the workmanship etc it can happen. Your Subaru Legacy is a good example of why we switched to a non Subaru brand of head gasket made by Six Star which we have had great long term success with. If you are having it done again you may check to see if that is an option. Usually a Subaru independent shop will be more likely to use them. Most Subaru dealers will only use the factory head gasket.
Sorry but no recommendations for a Denver shop. I do know that there multiple independent Subaru shops in the Denver area though so just ask around.
Good luck,

I had a 2000 Outback w/ failed head gaskets at approx 105K. Had kept up required maintainence and could document it. After the repair was done I contacted Subaru of America at the dealers recommendation and they were willing to split the cost and sent me a check for $750. Shortly after, I bought a 2006 Outback. I was assured that the problems w/ the head gaskets were a thing of the past. Unfortunately, my 2006 is now in the shop having head gasket replacement at 93K.
Well… I’m sorry to hear about your Subaru troubles. I am not surprised by the head gasket failure on the 2000 Outback. I am a bit surprised about the head gaskets on the 2006 Subaru though. We’ve seen a couple but it has been a much lesser frequency than the rest of older Subarus pre-2005. I guess we’ll just have to wait and watch on this one to see if it is just a few of them or if it develops into the same issue of not if but when will I need to replace my head gaskets.
Again, sorry to hear of it but if done properly your Subaru should be good to go for many thoundsands of trouble free miles.

Mike,
I have a 2001 outback and the head gkt is leaking like the rest. I like my outback but my mechanic said to get rid of it now. He put stuff in it to help stop the leak too. So far no more leak but the engine light stays on probably because of this. The dealer said it will cost 2000.00 to fix. I would rather buy another car. I did not know there was a recall and subaru dealer didn’t tell me. Suggestions on what to buy that it’s a good car to trade for? Would get another but can’t trust them now.( thanks
If you are looking for another Subaru I’d suggest a 2006 or newer. These seem to have a much lower head gasket failure rate thus far for what I’ve seen throughout my shop. Also if you are looking at other makes and models, I suggest purchasing an online subscription to Consumer Reports. (about $25 per year). This will allow you to review all makes and models new and used.
Good luck,

Mike – Mine is a 2003 Forester (VIN manufac date is ’02) w/141K, manual trans. Started smelling odor like hair burnt in a hairdryer a few months ago; mechanic found no problem. Started smelling antifreeze outside car after operating; no signs of leaks in engine compartment or on ground. When weather got very cold (below 20), could smell antifreeze inside car if I turned on heat as soon as engine started; had to wait at least 5 minutes to turn on heat to prevent odor inside car. Also had problems stalling, esp. in reverse, & the radio failed to turn on once. After each stall, must turn off engine & pump clutch at least once before it’ll start again. Checked engine compart again; battery fluids OK, powdery buildup on contacts, no sign of coolant spray/leaks, but coolant in tank looked like oil. Took to mechanic & he said 1 head gasket is leaking; he wants to replace both sets “because they’re the same age & the other might leak too”, and also suggests replacing timing belt & H2O pump even though they were done at 90K “because we’re gonna be removing them anyway”. He replaced the coolant & did an oil change for now while I look for 2nd opinions. Does his diagnosis sound legit? How about the course of action/repairs he suggests?
His diagnosis sounds legit for for the loss of coolant and oily coolant recovery bottle. All the other problems are a random mix of things that I have no idea where to begin without seeing the car. The water pump and timing belt are a good thing to do if you can afford it but if not, they should still last since they were only done 50k ago. (a timing belt is good for 105k miles).
Good luck

Thanks Mike. The stalling is apparently due to a bad spark plug & wire, which might account for the burnt hair smell as well. SO I guess from your answer that I’ve gotta redo the head gaskets…rats! The estimate was $2100!
Hi Mike,
You would not believe what a godsend finding this site is to me.
I have a 2003 Impreza Outback Sport (249k miles) with a myriad of problems that all seem to stem from the head gaskets.
I have replaced the engine @ 230k miles with a 2.5L from a 2006 Impreza Outback Sport that had 40k miles on it, and now, at a total of 59k miles on it, the head gasket has warped beyond belief, my cat system has killed out three O2 sensors (haven’t been able to figure out why until now), and I’m looking at 2500 plus in repairs to fix this all.
I wouldn’t be so sure about those 2006′s being more stable. I think it’s just that not many people with 2006 and newer have over 150k miles on them and so these issues aren’t prevalent yet.
Here’s where I’m straight up frustrated and GRATEFUL because now I know I’m not alone.
On the original engine I had to have the heads remachined and new gaskets put on at 100k miles (which was in 2005)–I was in Bowling Green, KY and there were no Subaru dealerships close and the only Subaru mechanic in town didn’t mention anything about a recall or issue on this problem.
I am the second owner of the car (bought it from the first owner at 96k miles, who had records of every maintenance done, which was everything required maintenance you can think of, and the records of it done through the local subaru dealership). When I purchased the car, I asked about any recalls and they said they had never received anything from Subaru. I did my own research and nothing had come up about a recall of this nature.
Now I don’t know if that was because in 2005 the 2003 models hadn’t experienced issues yet because the car was still so new or what. But I do know that when I had the heads remachined, it was because the Nissan dealership (which partnered with subaru even though it wasn’t officially a subaru dealer any more) couldn’t get new heads for my car because they said Subaru hadn’t made any replacement parts at that time. Whether that is a crock or not, I ended up out of my car (driving the dealer rental which my insurance paid for) and stuck in KY for a week (I travel for work and use my own vehicle) while waiting for the heads and head gaskets to be fixed/replaced.
Now that original engine ended up throwing a rod–mechanic said that the piston was literally launched through the engine, kind of like an arrow through a heart. So bye bye original engine.
Enter the picture, current engine. I had the old engine replaced with this used one in spring 2010 (which came from a totaled 2006 Impreza Outback Sport w/ same specs) and then commuted from LA to Las Vegas twice a week over the summer. On occasion, I would also be assigned to Death Valley. This is in the middle of summer where it’s 125+ degrees Farenheit in Death Valley. So, naturally, after driving from LA to Death Valley with the AC on, and noticing that the car is starting to overheat, I would turn the AC off, turn the heat on, and the car would stop overheating, or at least not overheat as much (temp gauge would show a little over half way between hot and cold). I thought this was odd, but when I would get to Las Vegas, it would stop overheating and I could drive around town w/ the AC blasting and didn’t have any problems. After consulting with my mechanic, he found that I had a slight oil leak, though he couldn’t figure out exactly where it was coming from. Said not to worry about it unless I started noticing my oil going down considerably.
So, then this winter… I’ve been in a Utah winter for late 2010 to current where the snow and cold have been very cold and the car is still overheating. How a car can overheat at 6 below 0 is beyond me. Anyway, long story short, I was driving and noticed when I stepped on the gas, my rpm’s 0′d out and it took pushing on the gas three or four times before it would take to the gas and go. This lasted all of about 1/2 mile (thank gods I was on the way home when this happened) and it died in my driveway.
Next time I tried to start the car, white smoke is blasting out of the ignition and I notice a slight leak under the engine, which was not oil. Radiator fluid is full, and I couldn’t figure out what would be leaking. Didn’t look like transmission fluid either, and definitely not anti-freeze. So I got together with my brother and law and after he checked a few things, he confirms what I thought…head gasket is blown…
*note* The check engine light has been on for a year with this error that the O2 sensor is bad…AGAIN…the THIRD O2 sensor that I’ve replaced in three years has gone bad..not to mention I’ve replaced two of the three catalytic converters since 2005.
So…now my dilemma. I have already been through enough engine repairs with the previous engine and am concerned that after another 150k, I’m going to be replacing the engine again, even after fixing the head gasket. I’m already at 250k on the original car, though have replaced struts, wheel bearings, brand new tires, etc…
The question is, are there any known reports of issues with the 2006 engines going through and throwing a rod after 250k miles even with maintenance and regular oil changes???
And what’s with the cat system eating the O2 sensors yearly?!?!
Thank you soooooooo much for this site! I absolutely ADORE my subaru and have this total attachment to it, but I am getting ready to cut my losses and get a newer one…I can’t keep forking 2500-4000 every couple of years in repairs…and if that’s what the forecast for this Outback Sport is, she’s going to have to go…
Peace…

Also,
I have the head gasket problem on a used 1997 subaru legacy outback wagon 2.5 DHOC that i bought 2-3 years ago. It overheated a couple times after i had it a couple months. Took it to 3 or 4 mechanics and they found no problem. I remembeed from several years about bad radiator cap causing overheating so i put on a new cap and car did not overheat untill here recently when over heated 4 or 5 times getting very hot. I would drive yntill the teop gauge went to Hot the shut engine off and coasted untill it came to stop then waited untill it cooled some the done same again untill i got it home. Put new rediator cap with no change this time so it looks like head gaskets are blown. I have a backyard mechanic who will do the job at reasonable price but i need to furnish parts. Since i am on SS I AM looking to find parts at reasonable prices. Seen your blog here about the newer design head gaskets but cant find the price. What is the cost of the new design head gaskets?

Hi Mike,
I’m sorry to hear of the head gasket issue with your Outback. The Six-Star head gaskets for your Subaru are available on our website and are $101.74 for the pair. You’ll want to order the set for the Phase I DOHC 2.5 engine.

Hey Ted,
For a 2.5 to throw a rod at all is a rare exception on any Subaru other than possibly the 1999 2.2 engine. Usually the only engines we see throw rods have been run low on oil or abused and as I said it’s very rare. As far as your 02 sensors? I don’t know. Are you using genuine Subaru sensors? As far as the cat’s go, they themselves don’t harm the O2 sensor at all. It’s whatever is going out the exhaust like possible blowby or coolant going out the exhaust. It’s normal to get 50-100k out of them.
Not sure if this helps you make a decision but at least it’s more information to ponder.

I am fortunate to have found this site. Mike you appear to know the details of this issue. Luckily I am also just across the pond in Bellevue. I’ll be seeing you folks soon for a set of those gaskets.
Hello Mike, you have given fantastic information here and I certainly do appreciate it. I just purchased a 2002 Subaru Forester L, 2.5 with 92,000 miles. I have driven the car over the last few weeks and it drives fantastically. From time to time I get a scent of anti-freeze. Other times I do not. I have checked the level a couple of times and all seems where it should be. This vehicles was owned by 2 other people prior to me. This scent of anti-freeze I get the signs of the head gasket leak or could the scent come from the anti-freeze reservoir? Also I have had no signs of any type of overheating or at least from the gauges. The vehicle is in excellent condition in and out and plan to keep as long as possible. If you deem necessary I would like to invest in the 6 star gaskets. Lastly, I have a great local mechanic and shop, done lots of work on different cars I have had. Would you recommend that Subaru do this job if needed or go with my own shop? Thank you so much for your time.
Hello, I would suggest you have the underside of the vehicle closely inspected along the head gasket seams to see if there is any coolant residue. There isn’t a smell that comes out of the coolant resevoir.
If it does ever need them replaced, the Six-Star is the best option I know of at this time.
Good luck,
Mike

I purchased my Subaru Forester new in 2002. Before the waranty ran out I noticed a slight antifreeze smell an loss, but only occasionally. I took it to the dealer and they informed me that they could not find a problem but the problem continued. Now at 102,000 miles the antifreeze loss has increased and I have developed an oil leak. I can only assume the head gaskets have failed. I contacted Subaru and they informed me that they were not aware of any such problems which as you and I know is a lie. No consumer confidence here. You might say this is my first and last Subaru.

Hi Mike,
I am currently looking for a Subaru to buy (1st Subaru) but had come across nothing but bad news about the head gasket, O2 and Cat issues. Just wondering if a 2003 forester with 250,000 kilometers with bad gaskets (causing fluid to be pushed out of overflow), would be a good buy. If I bought the vehicle, at a good cost of course, and replaced the gaskets with the 6 star. Would it be a good decision considering the mileage or should I stay away from this all together? I’m just wondering because I’m not sure what kilometers should be expected from a Subaru engine. Thanks for your time and input.
Hi Mike,
It could be a good buy if you buy it for a good price. The problem is unless you know the history of maintenance and how badly it’s overheated in the past, there could be some costly complications beyond just replacing the head gaskets with Six Star gaskets. If the maintenance was poor, you may end up with a car that burns oil etc even if you repair the gaskets. Also, the overheating can weaken the rings leading to oil consumption. You also don’t know until the engine is apart what shape the block is in. If it was overheated badly it can warp the block surface and the individual cylinder roundness. At that point you may as well install a new or reman shortblock along with doing a valve grind on the heads. If you get it for such a good price that you could still afford to install a complete engine and still be in it less than it’s worth then it may still be a good deal. (assuming the rest of the forester is mechanically sound)
Good luck, Mike Corbin

Hi Mike. I am praying you can help me figure out what to do. I have a 2003 Subaru Legacy that has 114,000 miles. Last year I had to replace the water pump,some belts and a muffler. About 8 months ago I noticed that when I ran my car to warm up it would bring a burning smell into the car. I then noticed a drip or two every once in a while of oil on the ground. I took my car to a place that only work on Subaru. They looked my car over and said I need a head Gasset replaced with a price of $1600-2000. I did not have that kind of money. They told me I had time to save up money and get fixed later. Before I hand over that amount of money I took my car to another shop. They told me it was seals that were leaking. So now I am confused at how it could be 2 different problems. But my question is that it is now 8 months later, if it is my head Gasset is it even a good idea to fix? Was there some damage done to the motor if the coolant was now in there. I dont know if I pay out $2000 and find out my motor got out of wack or what ever else could have been happened from driving around, my car has lost its get up and go.Is it too late to get my car fixed? Please help me!?! I am clueless to cars and to how long it was ok to drive with needing the head Gasset replaced? Please help me decide if it is not too late to repair or should I not bother putting the money into car?
Hi Natalie, Understand if it’s the seals and or gaskets leaking on your Subaru will help determine what to do. In many cases when the head gaskets are leaking, you are able to smell some unpleasant smells from either hot oil or coolant on the outside of the engine evaporating and entering through the ventilation system. It is probable that with that mileage, both the engine seals and head gaskets are leaking. How bad is the question. It does sound worthy or repair since ith only has 114k miles and to your knowledge has not overheated yet.
The price is reasonable for the amount of work that must be done (about a 2 day job).

My 1999 Subuaru Legacy 2.5, just purchased came with brand new head gaskets and typical parts replacement overhaul (water pump, etc.)
As soon as I got it home, there was evidence of a leak, so they took it back, apart and replaced the head gaskets again.
After 700 miles, my check engine light went on. THe first symptom was the temp gauge shot up, and dropped to normal in a second. then gradually got hot. I drove it in and asked for the solution, thinking thermostat or fan switch.(I never lost coolant) My guy said “head gasket”. My hub began driving it for short trips over a 2 week period, no problems over 200 miles. Check engine light comes on again, I take it tro someone different who determines a blocked radiator—replaces radiator,thinks problem solved. I drive it home- 18 miles later, gets hot again. Anyone have any ideas about this? We are frustrated and can’t invest a lot more money in this car.
I think it’s going to come down to the quality of the diagnostics. If someone is not thorough there can be other issues that cause the problem to return. The first step is to test for hydrocarbons in the cooling system with an emission analyzer. Then, if there are hydrocarbons, no radiator, thermostat etc will ever solve the problem until you resolve the fact that exhaust gasses are being pushed into the coolant.
On a Subaru, the engine is aluminum and there are various things that can occur that damage the aluminum surface so that the head gasket does not seal well. A hairline crack in a cylinder that was overlooked during the repair could cause the symptom. An overly agressive mechanic cleaning off the old gasket material could damage the surface thus keeping the gasket from sealing properly etc. Also just poor quality gaskets and or installation procedures can lead to repeat failures. Did the shop measure the cylinder head and block surface before re-assembling the engine? Warpage of the aluminum due to heat can also contribute.
Now, if there are no hydrocarbons in the cooling system, a thermostat, radiator or waterpump certainly can manifest the symptom you are talking about. Not likely, but you can’t rule it out.
I recommend making the engine block surfact is perfectly clean and have no gouges, imperfections or warpage beyond .002in. Same goes for the heads. If the cylinder heads have a groove worn where the gasket compression ring is or is warped, it should be machined also.
I hope this helps you get to the bottom of the issue.
Take care,

I have a 2008 Subaru Legacy Sedan 2.5i that I bought 7 months ago at 88k miles. It had high miles due to a salesman that had it. I have had the oil changed 3 times now and was told today that my head gaskets are seeping oil and that they would keep an eye on it but if needed to be replaced would cost 2100. I have many problems with this whole situation, mainly being this car doesn’t have that many miles on it and I just got it less than a year ago. How is that a powertrain warranty doesn’t cover head gasket problems? Have you seen any other 08′s with this problem? I can’t seem to find any other person that has had a problem with the 2008 Subaru Legacy.
Hi Heather,
The price quoted for the head gasket job is about in the range I see. I like the idea of keeping an eye on them because at this point they are just an oil leak. If they didn’t qualify how bad the oil is leaking you may want to find out more details. We’ve seen many Subarus with oil residue around the head gasket that wasn’t much of a leak and it tended to just ooze over the years without ever failing. It may be years or many miles before you ever have to replace them. If they said coolant was leaking, I would be much more concerned.
Also, the powertrain warranty does cover head gaskets. Unfortunately you are beyond the 5 year 60000 mile warranty (unless you purchased and extended warranty)
As far as any 08′s with that problem…. I haven’t seen any yet (although yours does have much higher mileage compared to the ones we see at our shop which tend to be still in their 5/60 warranty)
I hope for your sake it’s just a minor seep and isn’t anything to worry about. If they do ever fail and need replacement in the near future, it never hurts to call 1-800-SUBARU to see if they will help even though it is out of warranty.
Take care,
Mike
I think I’m going to have another mechanic who I trust do a compression check on the engine and see if anything comes up. They only said it was seeping oil and to not stress out about it yet, but of course that’s hard to do knowing it could cost 2100 to fix. Is it true that the head gasket is made out of aluminum? I know that aluminum breaks down after awhile and isn’t the strongest material for an engine part. It sounds like Subaru should be sued for all the problems people have had with head gaskets over the years! Thanks for getting back to me quickly and if I have any other questions I will send a comment.
P.S. They did say there was a crease but I didn’t get the details as to where the crease was. Would that be the seal? And could the seals just be replaced and fix the seeping problem. Still learning about how the head gaskets are set up.
I also have a 2003 Forester less than 60,000 miles on it to date – just local driving. I am the sole owner and it was bought new and well maintained. Recently, I noticed what I noticed what I thought to be oil dripping from the driver’s side under carriage. Took it to our mechanic who diagnoised it with a leaking head gasket!!! This (honest) mechanic suggested that we contact Subaru because it was unusual to have head gaskets laeking on a vehicle with less than 60,000 – especially a Subaru!
We contacted Subaru Of America headquaters in N.J, and they required all my maintenance logs to be sent over to Subaru headquarters, and the vehicle would need another inspection at an authorized Subaru dealership. The Subaru dealership found that not only one head gasket was leaking, but (now)the other gasket was seeping also! We could not believe this! SOA offered $500.00 in repairs toward a $1,700.00 repair. Fear of further damage to the gaskets, we had the repair completed at the Subaru dealership. After the repairs were complete I discovered(on-line)that many other 2003 Forester owners were experiencing the same “gasket problems” with vehicles 60,000 or less. I decided to write a letter to Subaru and ask them to recall these models, and to do the “right” thing cause it’s the right thing to do! I also said there are many LOYAL Subaru owners experiencing this same situation and they are frustrated too. Today I received a letter from Subaru stating that ” Subaru does not warranty the head gaskets as part of their warranty!! And by giving me a $500.00 goodwill repair gesture, they have fulfilled their obligation in full and have gone beyond” (exact wordage)
I was so dissapointed to read this from a company who is well aware of head gasket problems in many of their models. We may need to contact a government agency that may determine this to be a recall issue. I just sold a 1996 Honda – never a problem – regular maintenance was all it required. I suggest each person reading this who has head gasket issues write a letter to SOA headquarters in N.J – maybe they will get the message! So deeply dissapointed in Subaru of America at this point. This Forester was a birthday gift from my husband!
Hi,
I urge anyone who has had head gaskets isuues in any of their Subaru models to write a letter to SOA headquarters in N.J. Attention D. Schwartz. I also found a government agency Recall.Gov that you can file a complaint. Subaru must do the right thing concerning this head gasket issue: Issue a recall on your faulty models – you owe that to your loyal customers!

Hi Heather,
Subaru does not use an aluminum head gasket, rather a steel one. You may have been mistaking the fact they have an aluminum engine.
Cheers,
Mike
Not sure about a “crease” either.
The main thing is if it’s only seeping, just have them keep an eye on it. It could be a matter of years before any repair becomes necessary.
Mike
Dear Lucia,
I’m sorry to hear of the head gasket issue with your Subaru Forester that has so few miles on it. I understand your frustration but I am glad to hear you did get some help from Subaru. I wish they were able to do more for you. Others haven’t been quite as lucky.

Hey Mike,
Great site, lots of info. I have a 2000 Subaru Outback with close to 150,000 miles on it. I am currently living in Mexico at the moment. About three months ago, I hit a tree branch that had fallen in the middle of the road. Put a hole through my grill and damaged the hood and the radiator. Supposedly everything was fixed. Since finally getting it back, it has been randomly overheating which it has never done before. Another weird thing is that my alarm system (didn’t know I even had one) comes on when I lock all the doors and unlock with the key and lift the door handle. This is totally new. I don’t have a remote, and when I lock all the doors from the drivers side and shut the door it beeps, as it always had, but now when I try to open the door it goes off. Which as I said never happened before. When I got it back the battery was totally dead. That was when I first noticed the alarm issues. Anyhow, everything is fine with the car. New thermostat, new water pump, radiator is fine, heater core flushed, and still it randomly overheats about every two weeks or so. Also when it overheats the air conditioner stops working. Could this be an electrical issue? Maybe a shorted module that services these components. Headgasket? I have no idea. My mechanic here thinks it might be some electrical issue dealing with the alarm system. Thanks,
Landon
we just had our 2001 legacy outback engine rebuilt is it advisable to add coolant additive. The heads were torque different then subaru’s spec’s. The shop that we had engine rebuilt at has not had any head gasket failures.
Hi David,
If the head gaskets are genuine Subaru gaskets, then I would advise the Subaru Coolant Conditioner each time the coolant is renewed. If they are other than Subaru gaskets, I would not use it.
Take care, Mike Corbin
Hi Landon,
I think that you should have someone check for exhaust gas in the radiator. If the head gaskets are failing, it can cause air pockets in the cooling system thus overheating the vehicle without actually having a leak. I doubt it’s an electrical issue unless they forgot to hook up the electric fans that should come on at 208F.
As far as the alarm goes, you may want to by a keyless remote and have it programmed to the car. The car originally has a keyless entry system.
Take care,

I need to know if my 2001 subaru legacy outback EJ 2.2 engine is an interference or a non-interference
Hi David,
It will be an interference engine. It should also be an EJ25 unless you are outside of the U.S.

Hi,
I have a 2000 Outback (92K miles) that I just noticed has lost it’s coolant. None is visible in the radiator and there is just an inch or so at the bottom of the overflow container (cold). I don’t see any visible coolant leak nor have I smelled coolant. I have not (yet) seen overheating. The last time I checked the level was about 2 or 3 months ago and I thought it was OK. Is it safe to replenish the coolant and drive a bit to get a handle on how bad the leak is? Also, if I add coolant, should it be genuine Subaru coolant? Would I also need to add some conditioner?
Thanks,
Larry
Hi Mike and whoever else cares to reply.
I have a 2003 Forester with 11,500 miles on it. We bought the car at Wilmington Subaru (now out of business) with about 30,000 on it in 2005 and no extended warranty.
My mechanic informed me that I had a leaky left head gasket along with a power steering leak and leaks in 3 parts of my exhaust system.
Now I get a recall for lower control arms broken at hanger brackets due to corrosion caused by road salt.
My mechanic told me to have a Subaru dealer Inspect the front lower control arms and they are bound to see above mentioned leaks. He said let them inform me about the other problems and to work out a deal with them: probably just for the gasket issue. Who knows? Total estimate for all repairs around $5,000 which is roughly what we owe in on it.
Should I have another Subaru dealer look at it first or call 1-800-SUBARU3 and feel them out about the issue.
If I can get half of or at least $500 off, mentioned in above posts, that would help just a little.
My main question is what’s best way to approach Subaru about this.
Thank you,
Doug
Hi Larry,
When you suspect that you may have coolant loss on your Subaru here’s a couple of steps you can take. First of all after the car has been sitting overnight (before starting it) remove the radiator cap and top off the coolant until it is full to the brim. Install the cap and then add coolant to the overflow bottle until it is just above the bottom line on the bottle. Monitor it’s level for a few days first thing in the morning. Check the radiator and the overflow. If the level remains the same for a few days, increase the duration between when you check it to see how long it takes before you need to add coolant.
It isn’t always head gaskets that cause coolant loss on Subarus. It can be the fact it just wasn’t topped up properly at it’s last service, a coolant hose that has a few drips from around a clamp, a water pump etc.
I hope you are fortunate and don’t need head gaskets yet.
Take care,

Hi Doug,
Wow, that’s low miles for a 2003 Forester! First of all, what kind of leak were you told of? If it is just an oil leak at this point at the head gasket, there’s no need to to much at all. It will ooze and eventually get worse but could take years and many miles. If it is coolant than I suggest moving foward with repairs. As far as exhaust, I’m not too much of an expert if it’s corrosion related. Out here in the Northwest they don’t salt the roads so we don’t see the complications that arise with exhaust corrosion and underbody components. If the power steering is leaking the question is how bad. I think that the first step is a second opnion to evaluate the nature and severity of the head gasket and power steering leaks. The exhaust leaks may speak for themselves. You may save some money on the exhaust by having a good exhaust/welding shop repair the sections instead of replace the exhaust. It may eventually need it but exhaust shops can be pretty creative.
If you do find that the head gasket is leaking coolant from the left side I would then call the Subaru customer service # and see about assistance.
Good luck,

Hi Mike,
I have a 1998 Subaru legacy — It had 117, 800 miles when I bought it, with a blown headgasket.
Since then I had my mechanic (known since 1999) fix the headgasket and a bunch of other issues — Cost $1600 + Tax — 12/08/11 — Drove it home — worked Fine for 2 days — started overheating again — Drove it back to the Mechanic — replaced the radiator — $300. Now it is still overheating again — I hear a bubbling/crackling sound before the Temperature starts going up again. I stop the engine — for 10 min — Turn the heater on high and restart the motor, and it drive fine until the same thing repeats. What Can i do at this point ? Any help would be greatly appreciated !
Hi Leonard,
Wow, what a dilemma. My first thought is to just ask for your money back. Not everyone is the best at repairing Subarus. If something was overlooked, done wrong, poor quality parts used etc. it may be in your best interest to stop where you’re at and start over elsewhere. Not knowing the shop, your relationship etc with them and their Subaru knowledge it’s a hard question to answer.
Keep in mind that every time the engine overheats it can do potential damage to the engine block, piston rings, cylinder walls and cylinder heads. If you have to keep taking the car back over and over and continue to overheat it, the engine could become unrepairable at some point.
The shop may have made an honest mistake and want to stand behind their work but you have the tough choice of deciding how many times you want them to try. All in all it sounds like you paid for a repair to solve a head gasket leak that has not solved the problem and you’re either entitled to the company repairing their work under warranty or just refunding your money so you can try it again elsewhere.
I hope it goes well for you.
Take care,

I have a 2008 Subaru Legacy with around 64,000 miles. The head gasket has developed an oil leak and it causes a very bad burning smell. I am wondering if others have this same problem so early? Also, would you suggest the Six Star brand gasket for this model year?
Thanks
Hi Mike,
First off I’d like to suggest that you contact 1-800-subaru3 to see if they will help. Your car is new enough with low enough miles I think you stand a chance of dealer participation. If they don’t help an you’re on your own, Six Star is a good way to go.
I hope Subaru gives you some help.
Mike
[...] you'll be fine if you use the right gaskets. I've used, and recommend, Six Star MLS. See here: Which head gasket is best for a Subaru? | Smart Service Subaru Blog The 2010 EJ has a revised head gasket, but I haven't heard/seen if they've employed a MLS gasket, [...]
I sure wish that you guys had a shop in Milwaukee! I have an 02 with a slightly leaking head gasket.
Early in the questions [Sept 28, 2010] you said that the head and block surface for the six star gasket replacement should be RA 50 polish. But later [July 7, 2011] you said they should be machined if they were warped or there was a “crease” from the embossed area.
So my question is: Do you normally machine the heads or do you normally just clean the heads prior to installing the six star gaskets. In other words, is the surface from the manufacture acceptable for the six star gaskets assuming that the heads are not warped or show any deformities.
Hello Mike,
If any machine work must be done on the head or block, a final finish of 50 RA (roughness average). If the block is disassembeled and there is no warpage or imperfections in the head or the block, the factory surface is acceptable. We find that more often than not, at least the heads need resurfacing.
Take care,

Hi mike,
In order to machine the block, does it have to be completely disassembled? Is there a way to keep metal out of the short block while machining it?
There’s no perfect way to machine the block without the chance of some metal making it down in the bore. Most machine shops want you to provide block without pistons.
Ask your local machine shop. They all have a little different way to go about things and different equipment setups.
Mike
Hi Mike,
I have a ’98 Outback Limited bought used in October ’04 w/82,000 miles. The head gaskets and timing belt were replaced by a dealer in February ’05 ($1400.00). Over the next 7 years (80,000 miles) I’ve invested in a new starter, 4 struts, 2 cats w/sensors, another timing belt, water pump, thermostat, miscellaneous boots and gearbox fluids.
Currently the power steering pump is leaking but I’m not complaining and intend to fix that also because I love the car…..but I hate the engine which two days ago started overheating.
Based on my observation of the engine’s operating characteristics, I suspect I’m pushing exhaust gas into the cooling jacket.
Are Six Star head gaskets my “final answer”? How much do they cost compared to the OEM’s? Is there any other/additional engine repair procedure(s) you can suggest that would increase the opportunity for me to perhaps move on to some body work?
Mike
Hi Mike,
I believe that currently the Six Star head gaskets is the best available choice for your Subaru. Although there have been a few reports of failures it’s the closest you can get to a “final answer” in my opinion. Items that help insure that they last include having the heads and block machined to a 50ra finish or better cleaning the threads for the head bolts and properly oiling and torquing the head bolts. You may not necessarily need the block or heads machined but if we’re going for perfection that would be the best you can do.
Take care,

Thank you so much Mike. I definitely intend to give Six Star gaskets a shot. I read above that they’re about $100/pair (reasonable when considering a $1500 – $2000 job). I just need to find a reliable mechanic who will install them without causing other complications. I understand that the engine needs to be pulled to perform the job and honestly the thought of anyone besides the dealer doing something like that causes me a little concern.
Also, I was just wondering, how long have Six Star gaskets been available to Subaru owners? Because I managed to get approximately 6 years/80,000 miles out of my last head gasket replacement, or at least I THINK I did (complications caused by a failing water pump made it hard to tell exactly WHAT was going on with my engine), I am curious to know whether there are any blogs from Subaru owners satisfied that they have used Six Star gaskets. Or is it too early to expect to hear from a Subaru owner that’s gotten say 100,000 miles out of Six Star gaskets and swears they’re the best thing since fuel injection?
Mike
Hi Mike,
My Six Star gaskets are on order and by the grace of God I managed to find a mechanic (more like shop owner by day, top fuel drag racer by night…this guy probably rebuilds engines like I change my socks) that I feel comfortable giving my car to knowing that what I consider to be major surgery will be performed. Anyway, this man seems enthusiastic about giving me a good job and is willing to work with me regarding the use of Six star gaskets.
However, he has asked me the following questions:
Is there any special type or brand of coolant recommended for use with Six Star gaskets (you’ve already stated that Subaru coolant conditioner will not be necessary) and are the manfacturers bolt torque specifications still applicable? If not, what are the bolt torque specifications when using six Star gaskets?
Mike
Hi Mike
I believe they’ve been around for about 3 1/2 years now (possibly longer but that’s how long we’ve been using them).
As far as finding happy end users, you’ll have to do a little google searching on that one.
Take care,
Mike
We prefer Subaru coolant (but no additive). Also, included with all the Six Star gaskets there is an instruction sheet on the proper torquing procedure.
