There is no PVC valve. There is a hose connected to an oil trap and an air pump. Different than a traditionally valved system. Volvo's use a similar system, except they attach the oil trap directly to the engine block to eliminate the need for a secondary air pump. The downside to that is the oil trap is eventually guaranteed to completely clog. You usually get about 125,000 miles out of the Volvo system before it's clogged, about the same point our air pumps conk out.
