You have to have some place for the air to be drawn in.
Patrick, help me out here. It was always my understanding that the PCV (Positive Crankcase Ventilation) valve was designed to vent pressure from inside the engine that was a result of combustion gasses bypassing the rings, a common and unavoidable process. I was unaware that any form of fresh air intake was necessary...in fact, as I understand it, the PVC system requires pressure in the crankcase and a vent could prohibit pressure from building.

Please set me straight on the function of the PVC valve/system....

Thanks!

Cheers!
