Positive Crankcase Ventilation: Description and Operation
Coupe
Description
The Positive Crankcase Ventilation (PCV) system is designed to prevent blow-by vapor from escaping to the atmosphere. The PCV valve contains
a spring loaded plunger. When the engine starts, the plunger in the PCV valve is lifted in proportion to intake manifold vacuum and the blow-by
gas is drawn directly into the intake manifold.
