Elantra L4-1595cc 1.6L DOHC 16 Valve (1995)
Positive Crankcase Ventilation: Description and Operation
PURPOSE/OPERATION
The positive crankcase ventilation system is designed to prevent blow-by gas 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.
