June 28, 200619 yr Recently having an oil leak repaired under warranty at the dealer, he said that the PCV shield at the back of the engine was also leaking. What the hell is a PCV shield??? It would be several hundred dollars to fix since they have to drop the tranny to get to this thing.
June 28, 200619 yr It's called the Oil Separator plate. It's on the rear of the engine. Maybe someone here has a picture of it with all the EJ22/EJ25 pictures for head gaskets etc. In the first EJ22 engines it was metal. By the mid 90's it was replaced with a plastic piece. Somewhere in the early 2000's it's back to metal. Yes, you must drop the transmission to replace it. Anyone getting transmission service or a clutch replaced should have this inspected. If it is the plastic type, it should be replaced. When it fails, it leaks oil from the engine rear and is sometimes mistaken for a rear seal until the transmission is removed.
June 28, 200619 yr More knowledgeable members might contradict me on this, but I wouldn't drop the transmission just to replace the separator plate unless the leak was enormous, which it rarely is. Wait for a better reason to drop the trans and then replace it. Just my opinion.

June 29, 200619 yr Author I had the HG leak fix done at one dealer, and it seems that he didn't replace this part. My local dealer said they probably corrected the HG with the engine in the car, and that's why they didn't see it or replace it. My local guy redid the camshaft seals and some other stuff under warranty since the other place had already done that work. Go figure...
