Hello guys im looken for advice. Im modifying the pcv pipage to handle possitive pressure now, do i need a one-way valve on the manifold to purge control valve tube? Ive looked at what this valve does and it freaks me out because any +pressure in the EVAP is bad right? Thanks again for all the advice and help ive gotton on this site! Grand prix for life!
