Re: Attn: Wicked (PCV crap)
Brad is correct in saying that fresh "metered" air is drawn into the passenger side head, circulated through the block, then drawn out through the drivers side head. But in my understanding of the system and its pressure area's, this only happens at closed/low throttle situations (high vaccumn). Then at higher loads or WOT situations the flow path of the passengers side is reversed due to the postive pressure inside the block now needs to be evacuated. With the throttle open both ports now see a vacummn signal, a weak signal, but enough to move the blowby gasses and building pressure inside the block.
