Subaru Head Gasket Repair Centre

What happens when your head gasket fails?

The head of All Drive Subaroo workshop explains:

A number of things can happen when your head gasket fails, depending on whether the leak is internal or external. In recent times we have seen an increase in external leaks on the 2.5 litre Subaru non-turbo engines. Subaru head gaskets using “multi-layer” gaskets don’t often fail, but when they do the failure is usually a result either of high mileage or poorly maintained cooling systems. Regardless, the single layer gasket will inevitably fail owing to inherent weakness and ineffective design. Our Subaru Service Centre can fix all Subaru problems, and help prevent them from reoccurring in the future.

Subaru Internal head gasket leaks

(mainly turbo models EJ 205, 207, 255, and 257)

The head gasket forms a seal between the Subaru engine block and cylinder head. It is the most critical gasket in the engine and the most difficult to diagnose. It seals both the combustion chambers and the coolant galleries in a Subaru engine. The Subaru head gasket has to cope with high internal temperatures and combustion gases under high pressure. Due to the extreme range of hot and cold temperatures and pressures on a large surface it is common for head gaskets to leak between chambers over time. These leaks are not externally visible. You may see bubbles in the overflow reservoir, or sludgy residue on the walls of the overflow reservoir, or you may experience random engine overheating.

When a head gasket fails it can either leak engine oil to coolant or coolant to the compression chamber. Either of these may cause engine damage and significant operational problems like burning oil and overheating, which may show up as white exhaust smoke. Occasionally, there will be a compression leak in the gasket, which will have to be replaced, before severe damage occurs. If the gasket fails in this way, a variety of problems can occur, from power reduction, or a rough running engine, to exhaust gases being forced into the cooling system, leading to the engine overheating and increased engine wear due to the motor oil being mixed with coolant.

Over the years we have not seen many non-turbo models with internal head gasket issues, while we have replaced many turbo WRX, STI, Liberty RS ¬¬, Forester GT/XT head gaskets, and if in the advanced stages, provided exchange engines. However, we have also seen an increase of liberty/Outback H6 EZ engines with internal defective gaskets at about 150 to 200 000km.

Engines EJ 205, 207, 255, and 257 DOHC 4-cylinder turbo from 1991-current, causes and options

Internal head gasket leaks in turbo models are usually caused by problems with one or more of the peripheral components, such as excessive turbo boost, failure of cooling fans, defective wiring, radiator leaks and blocked radiator cores. A blown head gasket in a turbo model usually indicates a replacement engine. There are two reasons for this: the OEM pistons consume excessive oil, increasing the risk of a future engine failure due to low engine oil. Also, it is common when a head gasket fails on a turbo model for bearings, crankshafts and other components to be damaged.

Subaru External head gasket leaks

(EJ251, 252, 253) and (EZ30)

A view of the cylinder head where external leaks often occur

Visible leaks and false fixes

These leaks result in coolant and engine oil seeping out past the head gasket and running down the cylinder head, where they are usually visible under careful inspection. They can’t be fixed by simply re-torqueing the head. They are sometimes hard to spot, showing only as slight staining where the head bolts onto the block. EJ25 and most EZ30 Subaru non-turbo engines are prone to this type of leak, which will often go undetected for some time as it is only in the advanced stages that coolant loss causes overheating. Customers who are attuned to their Subarus may report unusual smells, caused by coolant residue burning on exhaust pipes, and hot components; however most customers will be unaware of the problem. Additives such as cooling system conditioners, Bars Stop Leak, WWP-99, and Wynn’s Stop Leak should never be used as these can compromise the cooling system, causing overheating and serious damage to engine components. The only practicable solution is a proper Subaru head gasket repair, which is one hundred percent effective when done correctly.

Engines EJ251,252,253, SOHC 4-cylinder non-turbo from 1999 to current, Liberty, Forester, Outback, Impreza

In virtually all cases of head gasket failure in non-turbo 4-cylinder engines the cause is the design of the single layer OEM head gasket. If the problem is repaired using another OEM single layer gasket then the same issue will inevitably arise again. The mileage of the vehicle at the time of failure should determine the course of action. If the engine has travelled less than 120,000 kilometres it makes sense to replace the head gasket. At the same time, we advise performing a major service as this will mean a considerable saving in labour costs. If the engine has travelled 150,000 or more, consideration should be given to replacing the engine with a rebuilt or remanufactured engine from Subaru Engines Australia. External head gasket leak problems are rarely reported in turbo models, which are all fitted with the more robust multi-layer gasket.

Engines EZ30 DOHC 6-cylinder (H6) from 2001 to current

While these models are not as prone to the same problems as the 4-cylinder models, they have their own unique vulnerability, with the heater core. Unlike other models the EZ30 heater does not have a separate tap, and runs in series with the engine cooling system, meaning if the heater core becomes blocked, circulation of coolant is impeded throughout the system and the engine will overheat. The only early warning sign drivers might notice is an intermittent gurgling sound from behind the dashboard. If the heater core is replaced at this stage no further repairs should be required. However, if the early signs are overlooked, the engine will begin within two years to repeatedly overheat and the head gasket will fail, possibly damaging other components such as bearings, rods and crankshafts. The heater cores in these models commonly begin to fail around the 120K kilometre mark.

Advice and warnings from ADS

The earlier the better

The sooner the problem is found and fixed the less expensive it will be. If you have any doubts call us.

Known unacknowledged problem

Subaru have never acknowledged a problem with their single layer head gaskets leaving the only fix up to us.

ADS the only permanent fix

Subaru dealers use only the single layer head gasket. Only ADS use the multi-layer gasket for a permanent fix.

Susceptible models

All of the SOHC non-turbo models have the OEM single-layer gasket, and all will fail. We have the only permanent fix.

Early and advanced warning signs of head gasket failure

External head gasket leaks never result in immediate engine failure. It’s a slow process, and the attentive Subaru driver can spot the early warning signs and possibly save money on repairs by catching the problem before additional damage occurs. If an external head gasket leak is in its early stages it may be detected visually very easily but if it’s in the advanced stage there may be more happening that is not visible. It’s hard to know just how advanced a head gasket leak is, from external signs alone. Bring your Subaru in to us as soon as you notice any of the early warning signs. All Drive Subaroo have specialized equipment to test for hydrocarbons in the coolant and if these are detected early enough it might save your engine from a catastrophic failure and save you from a great deal of unnecessary expense.

Indicators of early stage head gasket failure include:

  • Visible fluid staining where the head bolts onto the engine block
  • Odour of engine fumes and coolant (smells a bit like coffee grounds)
  • Slow loss of coolant and/or engine oil
  • Excess fuel consumption

Indicators of advanced stage failure include:

  • Poor acceleration or loss of power
  • Leaking engine oil or coolant onto the front exhaust
  • White smoke from the tail pipe
  • Air bubbles in the coolant system
  • Low water level in the overflow reservoir or radiator
  • Unusual odour from the engine compartment
  • A sludge “chocolate milk” like appearance in the radiator
  • Radiator top tank exploding
  • Poor engine idle
  • Excess oil consumption
  • Leaking or exploding water hoses
  • Engine overheating

If you notice these signs, the head gasket leak is at an advanced stage and it is likely that the engine will have suffered other damage and will need to be replaced.

What happens if I delay repairs?

Delaying repairs to a leaking head gasket is a false economy. It might seem like you’re getting a few more miles out of your engine before paying for the repair, but continuing to drive with a leaking head gasket will cause more expensive problems to arise including:

  • Rusting of the cast iron bore
  • Engine seizure
  • Excess oil consumption
  • Warped cylinder head surfaces
  • Corrosion wear on the pistons
  • Warped engine block surfaces
  • Pitted cylinder combustion chambers
  • Worn valve seats

The Right Solution for all your Subaru Head Gasket Needs

ADS multi-layer head gasket–the permanent fix

Head gasket problems can be subtle things to diagnose and repairs can turn into a bad investment if the diagnostic groundwork is not properly done and other problems that need to be addressed are missed. The ultimate decision will depend on a number of factors, including the mileage, the type of engine and the extent of the damage. Your Subaru might require a simple head gasket repair and service, or a replacement engine. As a full service center, with everything from new engines to timing belts in stock, and Australia’s foremost team of Subaru expert diagnosticians, we can assess your needs and provide the best solution in a seamless operation, with no mistakes. Whether you have a turbo or a non-turbo model, and whether you need a new gasket or a new engine, we have the knowledge equipment and supplies to diagnose and repair, with the fastest turn-around time in the business.

 

If you’re thinking of taking your Subaru to a dealer, be aware that they will fit a replacement single layer head gasket, and eventually the problem will reappear. But that doesn’t have to happen: All Drive Subaroo use high strength multi-layer stainless steel head gaskets engineered and proven to ensure many years of reliable operation for all your Subaru models and aare far more durable than the OEM original item. Over ten (10) years and hundreds of repairs using the revised gasket, we have never had a re-occurring problem.

After many years of experience with head gasket repairs, and our own internal research, we have come up with two head gasket repair packages, one for the most economical yet reliable repair possible and the other, recommended, the best possible repair for long-term reliability and service from your Subaru.

Some Commonly Asked Questions:

Is the external head gasket leak issue also common in Subaru turbo models?

No, in fact turbo models are fitted with Multi –layer gaskets which have proven to be robust.

Can I still drive my Subaru while the head gasket is leaking?

For a while, yes you can. Should you? No, not unless you have a yen to spend a whole lot more money than you need to.

Does the H6 EZ30 and EZ36 Subaru engine suffer from the same problem?

Yes, these models do sometimes have problems, but not as often as the others, and usually caused by the heater.

How long does it normally leak before it damages the engine?

It’s impossible to say, but the range would run from a few weeks to a year approximately, depending on the type of leak, and on how the vehicle is driven.

Is it cheaper to buy a second hand engine or repair my own?

It may be cheaper to get a used engine from a wrecker, but this is usually a false economy. Given the inherent weakness of the head gaskets, it’s virtually certain that all the affected models will fail eventually.

Do all Subaru EJ25 engines suffer from defective head gaskets?

Yes, all EJ25 non turbo Subaru engines up to the current models are fitted with the inherently weak head gaskets.

Do you sell the head gasket separately?

Yes, we can supply head gasket kits. Please visit our online store.

How much does a Subaru SOHC head gasket repair normally cost?

Between $2,000 to $3,500 depending on the additional damage and the auxiliary parts required. Call for free inspection and quote now 02 9915 9900

Do Subaru dealers use the revised head gasket when repairing my vehicle?

No, Subaru dealers will fit the standard head gasket, meaning the problem is highly likely to recur if you own the vehicle long enough.

Is it good practice to replace the timing belt at the same time?

Yes it is good practice but it also depends on the mileage.

Will my check engine light come on if my head gasket was to leak?

No not usually but an O2 or AF sensor catalyst code may appear.

Why should I need to repair the bottom end when the issues are in the cylinder head area?

Replacement of big end and main crankshaft bearings may be necessary. This will depend on the mileage the engine has run, and the condition of the bearings. If your engine has high miles, or has overheated or lost oil pressure as a result of the leaking head gasket, the bearings will be damaged and should be replaced.

What are some other parts or services that may be necessary while replacing my head gasket?

There are a number of parts that need to be replaced with your head gasket, and some that may need to be replaced depending on mileage or condition. A list of these follows below.

  • Subaru engine gasket and seal kit
  • Subaru spark plugs
  • All engine oils and fluids (Castrol brand)
  • Subaru water pump and thermoset
  • Subaru engine oil and air filter
  • Heater unit core check and flush
  • Radiator service or replacement depending on inspection results
  • Engine bay and engine water hosing

    I don't write negative reviews thus I am not a keyboard warrior; this is my first.

    Acted in an unprofessional manner, was quoted one price and then would not honor that pricing. The error was made on their side as all the information they required and have I the documentation to prove it. The person who I spoke with either ignored this or could not grasp the emails and documented timeline provided. Deplorable way of doing business, in the end I was spoken to in such a tone that was contemptuous and dismissive and no, I never raised my voice or acted in manner that was anything but polite. It would appear self-evident that All Drive Subaru believe that as potential customers it is our privilege to be dealing with them.

    Was referred to them by a Subaru specialist workshop and I will certainly be making my feelings known to them in regards to ADS attitude and lack of professionalism.

    After our Forester engine blew up, we chose an ADS Level 3 remanufactured engine. Never has our car been so thoroughly inspected as ADS did. They sent photos of every part that needed to be repaired or replaced and we were amazed at the poor condition of some. Tomas and Robert gave us much advice along the way and communicated frequently to keep us fully updated re work and costs. We followed all their advice on what should be done and are extremely satisfied with the finished job - completed a week or so sooner than expected. We were most impressed with their factory when Robert took us through it. Two fills of fuel show the consumption to be 9.2 and 9.1/100km. We'll add a review in 12 months time and trust it will still be a glowing one.
    Thanks to all the ADS people for the great job done.

    After going through multiple performance garages having issues with aftermarket tunes, Gab at ADS was able to diagnose and isolate the mechanical faults that were contributing to a lot of my problems not picked up by previous mechanics/tuners. Car was given the full treatment and new tune and has never driven better! Thanks again to Gab for putting a smile back on my face when I’m behind the wheel of my Rex. Absolutely would recommend ADS to anyone.

    The guys at All Drive Subaroo were helpful with the selection of gearbox to suit my car and plans for it. The price was really good and the box was built for me in less than 2 days. They sourced Subaru genuine parts I needed and had all of it packaged up ready to pick up. Top quality work by top blokes. Thanks for helping me to get my car back on the road.
    The staff were terrific. Knew what I needed and could afford.

    Such a relief to be back on the road feeling secure that the Gearbox will do what it is supposed to do.

    thanks guys, and the mum who answered the phone sometimes.

    Big thanks to the guys at ADS, they saw me on short notice to prep my STI for a track day, sent me progress photos and kept me up to date regarding pick up. They go above and beyond, more so than your dealership or standard mechanic and make you feel really comfortable about leaving your car with them because of their attention to detail and quality work. Highly recommend!
    Recently we had to sort out what to do with our ageing Subaru MY 07 Liberty GT that we have loved for many years: repair or sell?
    A Subaru Service centre in our town, couldn’t help in our decision; it’s just getting old!!
    All Drive Subaroo in Peakhurst was our next stop. We ventured from 100 km away and were greeted by the best customer service person we’ve ever had to deal with in over 30 years.
    He was welcoming and courteous and promised to return the car that afternoon with an answer.
    We highly recommend that if you’re in Sydney,or elsewhere, and you have a Subaru, get it checked by All Drive
    Subaroo.
    That’s a slam-dunk: you’ll get the best service the best attitude and honest answers. Overall, a great experience.
    Chris I would like to thank you along with Issac and Niazi and all involved in getting my sons car back on the road for him.

    Unfortunately it was left up to myself to make arrangements to have his car repaired due to the long hours that he works and the stress that he felt he was under given the fact that he had only purchased the car in the last 3-4 weeks using all his savings to do so.

    I choose Alldrive Subaroo after doing some research online and reading all of the positive reviews.

    Being 53 I personally had no experience with these types of cars (I have added some photos of my cars to show how far my knowledge is with these WRX cars so you can understand)

    I can say that I was treated from the start to the finish like a VIP everything was explained to me in a manner that I could understand as well as all cost upfront.

    Its very rare these days to get the service that I received from every one that I spoke with along with pictures sent of the engine building process.

    All this gave me full confidence that you guys were doing the right thing by me knowing that I was six hours away lack of any knowledge and a father willing to do what ever was needed for his son.

    My son will be given strict instructions that his car is only to go to you guys for any maintenance/service needs that it may require

    Truly Thankful

    Rang these guys today for some technical advice. I am in South Australia, so can't call into their workshop. Rob was extremely helpful and took the time to talk me through some possible faults and steps I could take in diagnosing and repairing my sons Forester. Genuinely helpful and know their Subaru's. Will be calling again if I need the parts to repair. Thanks Rob.

    Just wanted to express my gratitude and big thanks to Gab from All Drive Subaroo. Upon having to pull over to the side of road due to engine acting up and not knowing the problem whilst waiting for a tow truck. Gab pulled over to offer his help, I was surprised by his kindness to offer on helping. After diagnosising the problem and temporarily fixing it, I was very appreciative of his dedication to help others in need and expertise. Again, thank you for your help tonight Gab. Would recommend All Drive Subaroo roo for all other fellow subie owners!

    I called up for advice having just bought my first Subaru, a clean white 04 liberty sedan 3.0SpecB six speed manual, (pre facelift, non-centre diff control) and had questions about the viscous coupling and gearbox, and the amazingly helpful bloke on the phone couldn't have explained it better or more simply, aftermarket LSD's, their own uprated viscous couplers, how to test the viscous coupler (by jacking one wheel and trying to move it, smooth resistance is what you want).
    What more could you ask for?
    I'm looking for more advice having just bought a 2.5 '04 wagon 5spd with low range, as a replacement for the sedan whose nose was broken, whacked by a young girl texting and driving her Mazda.
    I'll eventually give All Drive Subaroo some money for their services, gladly.

    Fantastic to Deal with. They know the product. Amazing
    I had planned a track day with my GC8 WRX STI on Sunday, so took it for a quick drive around the block on Saturday to make sure it was running ok. 5mins into driving it wouldn’t rev cleanly over 3000rpm. I’ve had issues with this before and thought my Sunday Track Day was over unless I could find someone to fix it on a Saturday?? All Drive Subaru was open so limped the car out there where Isaac had a look over it for me. After diagnosing what could be wrong he systematically looked at about 3-4 issues which was causing the car to do this which he explained to me as he went through them. This took 2.5hrs which was 2.5hrs after he was meant to finish his shift and leave but stayed because he wanted to find the solution to get my car running so I could get to the Track Day on Sunday. Needless to say after 2.5hrs of not rushing but fixing the problem and any associated problems which could have arisen on my Trackday the car ran perfectly. I went to leave & fix them up for the 2.5hrs Isaac had spent on my car and Niazi and Isaac said “Don’t worry it’s on us”!!! I would have been ready to pay anything for their effort and getting me to my Trackday the next day where apart from being disappointed I would have lost $300 not being there. I didn’t want to leave without paying for there service but they insisted.(I had never been there before). I’m actually blown away by a business that provides this type of customer service that is so genuine, honest and passionate. These guys are next level in knowledge, quality and honesty as a business and Subaru’s. I’m definitely a convert and will be using these guys for all my existing and future needs as I develop my STI.

    The stock gearbox in our 2006 WRX failed recently. After looking around we found All Drive Subaroo. We live in Darwin so organising over the phone and via email was essential. The staff at ADS were fantastic, from quotes to general information to best setups, delivery and everything in between. For what we got, price was good. Very happy customers and very impressed with the new STI box and configuration.

    If you want the best in everything, here is your absolute go-to Subaru workshop. I have all new diffs and transmission that have transformed my car into something more capable and durable than anything you will find in a showroom for any price, and my car does get tested in rough rural situations on a daily basis. Too many improvements to list here, but new engine is next. ADS workmanship is second to none.EDIT: It won't let me add another review, so I guess I have to edit this one.I got the ADS "level 3" engine upgrade for my Forester! My old one was a 2 litre but this is a 2.5L "hybrid". You won't get this engine anywhere but ADS and it's an absolute gem!Overtaking on rural highways is a breeze now, not something that takes minutes of tactical planning anymore. I can launch up motorway onramps to merge easily at traffic-matched speed.The engine is very responsive and 5th gear can be used quite readily because the engine has the torque to pull it, even with my longer-legged 0.738:1 overdrive that ADS previously did for me along with the diffs and gearbox. The extra torque I'm putting through those two Torsen LSDs is still handled beautifully even when giving it heaps around a gravel corner. Grips like a spider running up a curtain, as I like to put it.Attention to detail, communication with the customer, and quality of work are second to none. That goes for the driveline work I had done last time and this time for the engine. I travel 250km to take my car to ADS because I get ultimate piece of mind when I drive away, and that's important when you live rural like I do.Will be back ASAP for the WRX brake upgrade and get my tired old steering looked at. Absolutely brilliant turn-key experience.

    Thanks, guys, for your fast response to my queries about modified Subaru 5/6 mt. I can see myself with a new gearbox set-up very soon. Looking forward to a new driving experience.Regards,Iamgroot.

    I am very happy with the assessment of my 11 year old car which I knew had problems. I decided to go ahead and repair/replace items for my car which meant I did not have to purchase a new car. My car runs so much more smoothly and much quieter. It is also a much safer car to drive. Patricia

    The staff members got back to me rather promptly. I have not purchased anything yet, but it is looking good so far.

    These guys are absolutely fantastic. I have been having some issues with my car for some time that my previous mechanic couldn't be bothered to diagnose, let alone fix. ADS diagnosed the issues pretty much instantly, and were very helpful and transparent regarding my options for the large repairs required. Rob was fantastic to deal with, and was willing to answer any questions I had. He also helped me to prioritise the repairs I needed now over others that could wait, and gave me complete choice in everything. Thanks so much Rob! My car feels better than it ever has before, so I'm so grateful for the skills and knowledge these guys possess. Do yourself a favour and never take your Subie anywhere else!
    Since ADS has done the work on my Impreza the engine is great, the gearbox is working really well - especially on the hills. The Subaru is a pleasure to drive. Plus good people are working there who obviously know their trade. Every dollar I have spent there has been worth it. I highly recommend ADS.

    I made the leap from dealer Subaru servicing to ADS and won't be looking back. What a drastic change this was. From easy booking process to the servicing and to pick up, Robert is absolutely exceptional and the place is extremely friendly and professional. They really took great care in explaining the issues and the service process. The prices are fair and reasonable and I haven't had a Subaru service before where I have walked out already wanting to book the next one in. Car drives great now. Thanks again to Robert and the ADS team.
