Coolest Oil Catch Can

phunk

I have seen the exhaust PCVs used in the past and I agree that they are pretty slick and probably provide superior crankcase vacuum at high engine load where there is none in the manifold.

You are correct about how my PCV is running. My VC to IM are stock, and my VC to air filter tubes are unfortunately before the MAF due to blow-through MAF setup. But ya I played with it and it doesn't seem to be flowing enough unmetered air that my feedback cycles for idle and fuel trim cant handle it.

Usually all I will do (if needed) to a PCV system for a higher power FI car is enlarge the vents if possible, or add another if needed. My only real argument about why I dont use a catch can "just because" is only about space, organization, clean engine bay, etc. I prefer to eliminate anything in the engine bay that is not needed as, especially with twin turbos, space comes at a premium.
