Thanks serialk11r! After rereading this I was wondering what a 100% vacuum in the cylinder means for PCV (i.e. does it even need one, or would it actually increase crankcase pressure?)


Is this what you are talking about with the PV diagrams? (I've never actually seen this before.) Are you saying that with Valvematic, the PV "rectangle" will be flat rather than slightly curved?
