Two things can cause 0 compression in one cylinder: Burnt exhaust valve: EJ22 engines have tiny exhaust valves and it's very common to find this. Seized oil rings or even broken ring landing. Also very common, especially in a turbo engine. Either way, you can test it any way you can think of: it's gotta come out and have some work done to it.

After overheating so many times, it's for sure your headgaskets are blown now and the heads are warped. Don't even bother with block test for combustion gases. It's a waste of time. If the radiator is cold, then it's not getting warm coolant circulated through it. Therefore, the coolant in the engine is not circulating to where it gets cooled. You have a blockage somewhere, and it's likely the "cheap radiator stop leak" has something to do with it. Subarus don't like that kind of stuff in their systems.

Frankly the only way to really pump up one of those lifters is to drive the car like you stole it. You know, hit a freeway on-ramp a few times kind of driving. If the plunger moves freely and pops back up to its original height, it'll pump up, but only by driving it. I agree that putting all that stuff back on and driving is a good bet for right now. And yeah, if it was me, I'd be keeping my eye out for a good deal. Even as good as the 2.2 engine is, their life is still finite.

Needle nose pliars. After you get it out, look at the bottom: you will see a tiny hole. Hold the lifter upside down, with pressure on the plunger head and stick a small instrument into that hole simultaneously. This will release the small check ball and squirt the old oil out of that hole. Careful: it really does SQUIRT! Submerge the entire lifter in either mineral oil or some kind of solvent and work that plunger in and out until it frees up. If if won't free up in about 5-6 tries, it's not going to (usually).

I had a 2001 Forester L also which we bought with over 200K miles and a known bad head gasket. Being who we are, we put a rebuilt engine in it. At that point, it also needed front brakes, a new PCV valve and new O2 sensors. Other than that, I drove it for several years trouble free. It had nearly 270K on it when I sold it. It got good gas mileage, has tons of head room, lots of storage cubbies (boy, do I miss those!), a comfortable ride and handles very nimbly. My husband thought the front seats were uncomfortable, but I didn't notice anything wrong. Yes, the EJ25 SOHC engine is prone to leaking head gasket: if you have them done, make sure they are replaced with TURBO gaskets. In your price range, 2000-2002 are going to be your most likely options. I'd buy another one if I had to give up my LL Bean.

The EZ30 (H6) has a metal cover with approx. 112 bolts to take it off and they have to be removed in a specific order. It has 2 timing chains. The only thing I have heard of that causes them to break, especially at 70K, is lack of regular oil changes and/or low oil. The tensioners and idlers are inside that front cover and are lubricated by the engine oil, therefore it is absolutely critical that this engine gets maintained religiously. Yes, it's interferential. Extremely so. I'm sorry, but there's nothing you can do to help your neighbor but break the news to her gently. If it's still under warranty, unless she can prove proper maintenance, it won't be covered by a dealer, and these are hideously expensive to rebuild. How do I know? I have one in my car, and every one we have rebuilt that had low mileage went bad due to lack of maintenance.

Honestly, I would recommend finding a donor engine for your car. Any work you do to the heads, especially valves, is going to raise the compression ratio. With the number of miles on that engine, it's not a matter of "if" but "how soon" the rod bearings will give out and that will be a waste of $100 and your time plus busted knuckles. At 283K, that engine is nearing the end of its life expectancy. Put that money toward a decent junkyard engine. Any year from '96 to '98 will work as long as you match the EGR. We're Subaru engine remanufacturers, and I am offering you the same advice I would offer anyone who called our shop and told me what you have here.

How many times have you seen someone park their car, leave it in gear, take their foot off the clutch and it will roll slightly? All the time, that's how many! That bracket is there to help keep the timing belt from "jumping" for people who aren't careful. Sure, you can use the same oil pump, and in an automatic, it makes no difference, but for a manual, it does. BTW, early Legacys weren't interferential, so it didn't matter back then. Are you being argumentative for the fun of it, or are you just uninformed?

Larry, Here's what you need to know: As posted in a recent thread: These are the 5 things that absolutely MUST match up. You can use any year from 2000-2004 2.5 SOHC North American engine as long as these things match the original engine (don't even think JDM-the "plumbing" is all different): Left cam sprocket Crank sprocket EGR? (or not) breather tube on block (there are 3 styles) oil pump for automatic or manual You can swap stuff from the original engine long block to make it match.

Having been on both ends of this issue, whether a shop that either does bad work chronically, or just has a human screwup issue...the way the shop handles it is what matters most. Stay away from the chronically bad, ripoff, lazy mechanics. But if a reputable shop has an issue, if they address it and make it right with the customer: those are the places you want to go back to because they're going to take care of you.
