the down side of not haveing a PCV valve is that condensation will build in your valve covers and it looks like chocolate milk and it can get mixed in the
oil........
just running a breather on the end of a hose will help but it's not like haveing a PCV...
and by the way dosent your manifold have the 2 bolt plate at the rear where the tall
breather bolts on to the intake??? put it there....thats where i would put it...
