Integra LS Coupe L4-1834cc 1.8L DOHC MFI (1997)
Positive Crankcase Ventilation: Description and Operation
DESCRIPTION
The Positive Crankcase Ventilation (PCV) 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.
