VW/Audi PCV Service

The PCV valve regulates the flow of gases from the crankcase.

Positive crankcase ventilation (PCV) systems have been on just about every vehicle since the late 1960s. The systems route crankcase vapors and droplets into the intake manifold so they are burned in the combustion chamber or catalytic converter. 

The PCV valve uses the vacuum from the intake manifold to regulate the flow of gases from the crankcase. The pintle or ball inside the valve moves in response to the pressure difference between the crankcase and the intake manifold. The valve is typically located between the throttle body and cylinder head on a runner for the intake manifold.
