Re: PCV on 8BA
A pan vent filter is in fact on the diagram posted earlier. Same mesh-type as used in vented oil filler caps only stainless steel. So it's no better no worse at filtering fresh air into the crankcase than the original setup
As Robert suggested earlier, it simply entrains fumes into the intake draft when road draft is weak. It's not high manifold vacuum. So pressure differential is nil and works the other way when road draft is strong.
It's only purpose is to keep crankcase stink out of the engine compartment & cabin with minimal alteration of original venting setup.
