Default 02 WRX valve cover gasket replacement...

I've searched to no avail. I even scrolled (no search) thru the archives for a while...anyway.

Subaru has informed me that my VC gaskets are leaking and this has a $500 price tag and it turns out I'm a cheap bastard.

I'm mechanically inclined but very busy. Can anyone profide some input on the job. Is it done from the bottom? Can it be done on ramps? Do wheels need to come off? ect... write-ups? links?

By the price, I'm guessing it takes several hours but could be done on a Saturday afternoon.

Comments welcome.

Jody

Uh, no clue why they said it would be $500!! Check out http://www.subaruparts.com/diag/?mod...category=020-1
Each side has an outer valve cover gasket that follows the perimeter of the VC and then there's two gaskets that go around the area for the spark plugs. I replaced all three for my passenger side and it wasn't bad at all. For the passenger side, I had to take out the airbox, pull the two spark plug coil packs and undo the 8 bolts holding the valve cover on. The gaskets fit right into a groove in the VC. Some people mention using some silicone around the edges too, but I don't think it's necessary- I changed the gaskets back in the spring and no leaks as of yet. Make sure you don't mess with the crescent shaped gasket at the backside of the engine (there might be one on the front side as well) or that could cause you some problems. One thing that is a PITA is getting at the lower three bolts, but gear wrenches worked well in that case. I did the whole job from the topside of the engine bay.

Thanks for the replies.

Hopefully, I'll get some time this weekend to look at it...

Subaru quote to use sealant at the 'crescent shaped' seals and gasket joins. Also at the 'corners of the raised Crescents for the cam journals at the front. Personally. I also Threebond the Spark plug seals as on some models they become the outer section of the camshaft 'oil bath'. I threebond the entire lower section of the R/Cover all the way up the crescents front and rear, (basically a little everywhere except the top), I haver had mine in now for 145000kms and not even a stain. I have done dozens like this and same results. Just make sure everything is clean before re-assembly. Don't let any old pieces of sealant fall inside the Head/Cam area. Wipe all surfaces to be sealed with white spirit. Replace bolt seals, I always apply a thin film of Threebond to the lower three bolt seals to aid sealing in the lower section of the rocker cover as this sustains the 'wettest' environment. You will normally notice that the side that the D'Pipe is on will normally leak first. Heat kills the neprene gaskets. I have installed a small heatshield to the affected areas, (adhesive, foil backed-available at good parts suppliers), and I believe this has helped.
Cheers

^^^^
I agree - plus they are pretty inexpensive (don't forget the spark plug tube gaskets and the washer/gasket things for the bolts - sometimes you can re-use them, but since they are all 9+ years old, I'd just replace them)

Note: When you remove the bolt on the bottom at the back, a few ounces of oil may spill out. And then a few more ounces when you get the cover off.
Next time, I'll put some rags and an oil drain pan underneath first. :-P

Default 02 WRX VCG Replacement

I just did both of mine this weekend. 5.5 hrs, start to finish. It would have taken about 45mins if I'd had the engine out and on a stand at about shoulder height. The bottom/rear-most bolt needs a gear wrench, as previously stated.

I think the driver's side is fine, but I could see (and smell) wisps of oil smoke from the pass' side after a 40min test drive. I'd like to believe that it's just burn-off of the spillover while the vc was off, but a little more time will tell. I hope it's not warped.

I put a tiny bead of the grey OEM goo in the vc groove and a thin film on the flat side of the vcg, after doing a really good clean and wipe of the cyl head side. Dunno if that was a mistake or not - I couldn't resist on the basis that a little bit of goo between the gasket and the metal surfaces would have to be better than the results with none.

Both needed replacement - I'd been able to see seepage on the driver's side, but the pass' side had a thick layer of goo from ages of seeping. Only recently did that translate to being able to smell the oil smoke from the driver's seat.

I pulled the splash shield so that I could partly remove and wipe the oil out of a heat shield that serves as a nice spilled oil reservoir and to get a better look at the driver's side . Doing so was otherwise not necessary. I did drive the car onto my 4" lift mini ramps before beginning the job to save having to lean over that additional bit.

BTW - what is that black thing with a hose connector and three bolts at the top rear area of both vc? I looked at the pass side one when I had it off, and could not see a passage into the vc space. Re-connecting the hose for the pass side one was a real PITA.

I went with dealer parts for this job. The crescent seals were $11/each, and those washer-things were $4 each! It would otherwise have been a much cheaper project.

[QUOTE="Paulie V". One thing that is a PITA is getting at the lower three bolts, but gear wrenches worked well in that case.

Anyone know what size gear wrench is needed?

I get to answer my own question. Looks like a 10mm gear wrench, is the tool for the job.

www.rockauto.com has a whole vcg set with rubber grommets for $27 per side. A lot cheaper than going to the stealership. I went to them for the passenger side without looking at rock auto first and ended up spending just over $90.

hey ben!
if your valve cover gaskets were leaking you would see oil on the driveway floor etc as well as the plastic undercover as far as it being on the exhaust,youd only see it on the manifold or uppipe but now down the downpipe as you described.

now when you say out the turbo exhaust and down the downpipe im going to ahead and guess your talking externally,in which case the most likely scenario would be a bad oil seal on the turbo.or even possibly but not as likely would be the oil feed on on the turbo.
hope that helps!
