I don't have the equipment for the leakdown (I just bought the compression gauge a few hours ago). I do have a buddy that owns a shop but he's on vacation so I'm going to wait and see if he'll do it.

I put in a 323gtx PCV for now but I do have a question about it. I picked this valve up from a local store for about $4 but I noticed on many sites the 323 pcv they recommend for boost is between $15 and $30. Is there actually a difference?
