Default 2005-2008 models?

Are these still too new to say whether the problems have been fixed? Does Subaru still recommend using coolant conditioner?

Yes. Gaskets have been beefed up, but they are still concerned enough to require the conditioner.

I'm sure they are seeing a decline in the "epidemic" numbers of early 2.5 models, but not enough to stop with the requirement.

They really need is to beef up the engine, the thin separation between the coolant line and the combustion chamber has not changed for years.

That rear corner on the driver side is mostly problematic.

Default 2004 Impreza TS Gasket and Pistons changed

I have a 2004 Subaru Impreza TS and I like it generally.

It recently needed HG and piston replacement @ 45K Miles. Subaru agreed to cover it under warranty (even though it was a little above 5 years) with a $100 deductible - I really appreciate that.

This is the first car I owned where the pistons wore off BEFORE the brake pads! Looking at similar problems at the dealership - changing HG and pistons should be part of scheduled maintenance for Subaru's.

I feel I should chime in too...I'm in the beginning phases of figuring out what's going on with my '02 RS as well. I have 120,000 + miles on her, she is running really rough at idle & the exhaust blows out white smoke. I've changed the sparkplugs & all 4 of the plugs were drenched with engine oil. To my eye, which doesn't mean a thing..I don't see antifreeze mixed in with engine oil. I've been noticing that I've been losing coolant for some months now, with no apparent coolant loss on the ground or such. I've used the subaru coolant conditioner since they notified me of the "recall" from the very beginning. I've also changed the coolant 3-4 times in it's lifetime. The lastime being when I changed the timing belt, water pump, thermostat, & the hoses @ 96K. I'm actually hoping that it's just the head gasket & nothing internal. She's currently at my local mechanic for diagnosis.

Please explain. I'm guessing you work at a dealer, but what I am asking about is the piston comment.

White smoke = bad.

I hope it is not as it looks. Regular coolant changes with conditioner will lower your chances for sure, but as Xu said, it is a design flaw that is hard to correct with anything but a different design. Maybe Subaru will do something for you since you have done the proper maintenance.

I wish I had the same experience. Instead I had the most horrible experience ever, with every single person I talked to. Unless SOA comes forward and offers me some grand gesture I'm never buying a Subaru ever again. F*ck them. Acura here I come. If I'm lucky enough to have the money for one.

Sorry - that was me been sarcastic.

No I do not work in a dealership. GM is my initial - (my other id is GMHonda). My car started pinging/knocking @ 43K, some coolant loss too. Dealer wanted $1800 for new gaskets and pistons, some phone calls/dealer visits resulted in the one-time warranty extension coverage. In that period there were about 4 subaru's of varying age - (mostly newer) in the dealership having similar issue.

After fixing its working fine...

I still say subaru dealership mechanics probably have more experience changing head gaskets/pistons then most competitors out there. Pistons should not wear off at these mileages on an Automatic driven in city on flat mid-western roads. Even the brakes and Tires (original) still have quite some life remaining.

While I like it - its extremely unlikely I will buy a Subaru again!

what was the matter with the pistons? I doubt for 1800 the pistons would get done too.

The gaskets fail for a number of reasons and a lot of manufactuers have had the same issues with headgaskets. Toyota and Ford have massive campaigns. They try to tell you to add conditioner which is just leak stop crap. Any good tech would not fix his car this way.

I open a thread called " The Dan's 2.5", its nothing special, I am not hot rodding the car. Just posting some info for those who are clueless as to why this happens.

Well, for one, I think the gasket itself is crap and I told SOA this. I have pics I will upload of the old set. It was leaking oil externally, bad. Also the coolant sealing areas looked just as bad. It has been disintegrating in there for a while.
I just looked at the new dealer gasket kit. I am going to head to Pepboys to look at what Fel-Pro offers. I am hoping it looks better than the same junk the dealer has. If it is I will use Fel-Pro and return the dealer stuff along with some atittude.
I guess they have to replace the pistons if you have been burning coolant awhile.
Another thing I almost died when I saw was the oil separator plate behind the flywheel. What is the %$#@ is that supposed to be?
Granted, a car with 120k might just need some work but this seems to be another epidemic.

I am having trouble with Photobucket right now so I can't upload the pics of these gaskets. They are nothing more than steel coated with Plasti-Dip though, common. Fel-Pro usually boast " better than the dealer" and I have found this to be true over and over again. Where Subaru uses Plasti-dip Fel-Pro uses graphite. That is the stuff on the exhaust manifold gaskets and HELL, I can re-use those, they look great.
It very common for car manufactuers to use cheaper gaskets, they do buy a lot of them.

Subaru has spent a lot of time improving the gaskets. They have been bombarded with warranty claims of HG work which really cost them $$$. The current version of "steel" gasket is their latest "invention". They try to play well with the heat expansion coefficient rate with the material of the block to last. I just ordered 2 for my 01 (160K), the old part # has been replaced by the new one ("steel") that were developed for 05-06. How good are they? don't know. But given a choice, I would stick to these.

Ya I was like that at 133k also. The conditioner kept me going for a couple years. Changed to just water in the summer (plus conditioner) helped me stopped the leak completely for a while. Once the coolant was in, it started all over again.
Which side are you seeing the problem? I am guessing the driver side.

Just noticed that we joined the forum the same month even! Good luck to you. For SOHC, the HG change is not hard to do yourself, really. The cams don't even need to be disassembled. I am doing it the next 2 weeks.

So it sounds like the 2.5's are still prone to head gasket failure ie. it remains a weak point in the 2.5L engine design, but the new gasket design is meant to mitigate the problem to the point of not being a regular repair. It sounds like we'll only know for the 05-08s in a few years when they start failing or not.

Hey, I got a 95 impreza LX, and I'm having this weird problem with my coolant system. When it heats up to normal operating temperature, bubbles come out of the coolant reservoir. And if i play with the throttle, it bubbles a bit more. I don't see really too mcuh of my coolant dissappearing at all. If i get the car hot the coolant reservoir actually will fill up and it has definitely poured right out of the top of the reservoir before a couple times, thats mostly if I beat on it a little bit. But yea the reservoir's level changes rather drastically. Cold its I believe at or around the full line, but if i've been driving for a while, it will be nearly pouring out the top of the reservoir. Could it be the head gasket?

Is everyone with the newer engines running the proper coolant? I know the regular stuff has silicon additives and whatnot that eat away at gaskets. You should use Peak Global available anywhere, even walgreens/cvs/whatever.

I use Peak global + subaru coolant additive (that stuff is really expensive for half edible corn meal. )

Peak Global just uses straight up distilled water, propylene glycol, and ethylene glycol. Nothing else. They usually come pre-diluted.

Subaru does not recommend using any coolant that has additives because of the gaskets being prone to being eaten away by the coolant.

This might shed some light on as to why a lot of headgaskets have failed for NEWER engines.

I'm an 05 running at 46k, no problems yet. I have changed the coolant once, but it was not a coolant flush, just a regular drain. I used peak global.

SOA says that Subaru Coolant Conditioner should be used on all Subarus from now on, new or old.

I just had to state for the record that I finally got a SOA customer service manager to look over my file and she not only apologized for my whole ordeal, she is reimbursing me every penny. I was persistent and it stressed me out BAD, but she was good and made up for the fact that the rep kinda sucked. She treated me with respect which was all I wanted! So yeah, they redeemed themselves with that. I just won't be surprised if the HG fails again in another 100k miles.

tech at the local dealer told me the problem was fixed . that fhi realized the problem was the torque specs . that the newer ej's are torqued properly now .

we will see .

i do drain flush and refill my coolant before every winter

The torque specs have not changed. It was the design and construction of the head gaskets to blame. Which have since been redesigned.

First, this is my first post so hi!
Second, thanks for a great thread, i was searching for other stuff but stumble on that thread
Third, I'm French speaking, so bare with me :-)
Fourth, i have a strange job, i own a VW Vanagon restoration shop and guess what i do the most, Subaru engine conversion and i only use Impreza engine:


As i did over 30 engine conversion i thought i could comments on the head gasket problem.

Simple, it's there! I can't tell exactly why for now but Subaru as solve nothing lately. I only use late SOHC 2.5L non turbo engine, mostly 05-07, i can't use 08-09 for now because of CAN-BUS.

But here is what i think, inconsistency on some engine production in head torque sequence. Don't ask me who torque the head at Subaru engine plan, i don't know if it's robotic or not but something is wrong on some engine, i can't tell you why. I often have 06-07 engine with very low miles, some have less than 1000 miles and some around 25k miles, but in general they have about 10k-20k miles. Lately, i did an 07 with 16k miles and both head gasket were leaking, externally!

That said, due to the high price for a engine conversion, i change head gasket on most engines, even on some low miles one. Replace all timing component on all engine. This is how i found out that some head nuts had less torque than others (Electronic torque wrench).

Anyway, for the curious one you can check my engine conversion page, more than 500 engine pictures.
http://www.benplace.com/vanaru_eng.htm

Now, i said i stumble on this thread but sadly, I was looking for something else, very high oil consumption on some late engine, mostly 07. If there is already a thread he about that subject could someone point me out.

We have 2 x 07 with very high oil consumption, one took 7.5 liter (quart) in about 3500 miles (5500km).

For the sake of that thread, my van as a modified (210hp) atmospheric/normally aspirated 01 2.5L, it came out of a Forester (same engine as Impreza) at 120k miles, i can tell you that it had the original head gasket. I did over 30k miles on it since the conversion on an heavy 4500 van, no sign of head leak whatsoever when i got the engine out of the forester and no head leak now. Of course that engine was rebuilt and modified on the head side but the short block is all original. It doens't consume any oil at all. No piston slap, no knock nothing.

Cheers, Ben

yea man i also have very high oil consumption. 10 qts in 3000 miles!!!!!!!!!!!!

i changed over from the 5w30 to 5w 40 and then drove 600 miles and it doesn't seems to be consuming anymore .

maybe your motors would benifit from a thicker oil as well?

Sounds like you have some worn seals in your engine. Have you noticed if it was just leaking onto the pavement? Or is it getting burned?that seems a bit excessive.
