What is the Positive Crankcase Ventilation (PCV) System and PCV Valve?

The Positive Crankcase Ventilation (PCV) system reduces hydrocarbon emissions by scavenging crankcase vapors. It consists of the PCV valve, an inlet hose connecting the air filter housing to the valve cover, and a crankcase ventilation hose connecting the valve cover to the intake manifold. The PCV valve is located at the right front corner of the valve cover and restricts the flow when the intake manifold vacuum is high. If abnormal conditions arise, the system allows excessive blow-by gases to flow back into the air cleaner. Checking and replacement of the PCV valve is covered.
