Default Oil Leaks

I have a 1998 Impreza with the 2.2 engine. It has multiple leaks. Mechanic says it is leaking from the valve covers, cam seals, crank seal, trans pan (AT) and rear main. It also needs a new crank pulley with the possibility that the keyway may need repair (he has seen it before but hasn't dismantled anything on this car). He wants almost $900 to do all EXCEPT the rear main and pulley (as he does not know what is entailed with the latter and the former is such a big job that it is prohibative). Does this sound reasonable? He says the valve covers are a b*tch to do on these cars due to the boxer engine.

What do you guys think?

It sounds possible but i'd probably start with the valve covers. I did them in my 05 rs and it only took a few hours. Your engine bay should have more room so it shouldn't be too hard of a job. It's a really common problem in the NA motors so it's a good place to start.

valve cover gaskets are a breeze, make sure to remove the battery, windshield reservoir and what ever intake parts that might be in your way.

dang wish i was a mechanic thats about 2 hours worth of work

valve covers are cake.

cam seals are simple too once the valve covers are off

AT pan gasket is easy also

why do you think you pullly needs to be replaced thats kinda a random non wear part

I was told the pulley needed to be replaced as it is wobbling, but the mechanic wasn't sure if it was the pulley (easy fix) or the keyway (much more difficult as it would have to be welded and recut - he has seen that on Subarus and I had it years ago on my SVX)

Yes, I figure I COULD do it (mostly) myself, but my daughter is in Pittsburgh and I am in North Jersey. She is coming home in about a month, but I don't know for how long. Then again, it would probably take me twice a long (if not longer) than a "real" mechanic (ok, experienced mechanic) and I would end up cursing and aggravated, etc (been there, done that).

Default 2.2 235k oil leak runs great diagnose n fix assist

id like to just throw my hat in the ring. i have a 98 2.2 that is leaking oil from the motor. there is a small amount on the front, on the passenger side. however, the main issue is a leak on the passenger side, on the backside, possibly towards the top. the oil is getting onto the exhaust. the leak is slow enough that i dont need to add oil between changes, but its to the point where i cant get an inspection sticker. the motor runs great at 235k and i hate to give up on this car. (with inner axle boot, and balljoint repairs ahead of me)
i can throw pictures up if anyone would like to diagnose. otherwise, any more info not in this thread would be great.

Front passenger side is usually a cam seal. Ignore IAmTheSleepySubie's time estimates on how easy this is or isn't. He clearly has no idea what's involved with the cam seal. You cannot get at it easily by simply removing the valve cover. To get at the cam seal, you must remove the cam gear which of course entails removing the timing belt and tensioner and one of the timing pulleys. You'll also need to remove the valve cover to get a wrench on the cam to steady it so you can break the cam bolt free. In your case, that's not so bad since the likely cause of the leak on the rear is the valve cover gasket.

You're looking at about 5 hours of work if you've never done it before. Since nothing ever goes right the first time, you could probably count on 6 hrs of work.

I apologize for taking so long to get back to this thread with the result. My daughter came home and the car was still leaking. As she wasn't going to be home long, we took it to the Subaru dealer to diagnose. They of course started with "oh, you have lots of leaks here. Cam seals and crank seal as something behind the timing cover is leaking, rear main or separator plate,..." They scared my daughter saying that the car wasn't safe to drive. Because we were short on time, we ended up buying another car (at a different dealer - a 2009 Impreza 2.5 with Premium Package). As they only offered $300 on trade, I kept it and figured I now had a lot of time to deal with it. First thing I did was pull the timing cover. Everything was clean - cam seals and crank seal were fine, but something had been leaking from somewhere near the front. I pulled the oil pump and replaced the crank seal and the o-ring on the back of the oil pump. put it all back together, cleaned the engine and drove it for a couple hundred miles - both around town and highway. No more leak! Car drives great, no more burning oil smell, no more oil all over the rear of the engine. I ended up selling it to the daughter of a friend's girlfriend. As I know the people involved, I am kept informed about how the car is doing and last I heard, she loves it, other family members have been impressed with how well it rides/drives. And suffice to say I got a whole lot more than $300 for it - I got a fair price and all is happy.
