PCV System

Positive Crankcase Ventilation (PCV) system prevents hydrocarbon (HC) build-up in crankcase from escaping into atmosphere. PCV system is a closed type. It consists of a valve cover baffle plate, PCV valve and oil separator (except some models). Oil separator removes oil particles from blow-by gases. Crankcase vapors are routed from crankcase, through oil separator, to PCV valve, and into intake manifold to be burned in combustion chamber.
