The aftermarket PCV that I got http://www.partsgeek.com/catalog/2000/subaru/legacy/air_intake/pcv_valve.html doesn't fit my Sube.

Here's the one that's in there now.http://img411.imageshack.us/img411/8316/img0007jdx.jpg

The receptacle into which the valve is screwed has a hole in the bottom of it to accomodate the long end.

The aftermarket one won't screw in all the way because of the plate in the bottom of the receptacle where the hole is.

Also, the cap with the wire on it can't fit over the top of the aftermarket valve.

The stealership wants $53 for an oem valve. I'd just hate to pay such a rip-off price for one.

Replacement valves at online Subaru parts places are going for

$5-$9. My guess is that they won't fit my Sube either.

Possibly there are several different PCVs for the 2000 Subes. Which one is correct depends on the Sube's VIN.

Where do I go from here.?

The valve that's on my Sube now appears clean as a whistle and the engine is still running smoothly with plenty of power and no drop in gas mileage. It's likely the original one and has 60k miles on it.

How long can it last before I experience problems?

My understanding is that you can clean them and as long as there still clicking back and forth there good.

In terms of keeping a PCV valve from sticking or if it's clogged, it can be cleaned. It's possible for the spring in the valve to eventually fatigue, causing the operation to become out of spec, but that isn't likely to happen for a long time. You can probably continue to use the original one as long as you don't notice any change in engine operation.
