Crankcase Ventilation System Inspection/Description
A crankcase ventilation system is used in order to provide a more complete scavenging of crankcase vapors. The air cleaner supplies fresh air through a filter to the crankcase.The crankcase mixes the fresh air with blow-by gases.This mixture then passes through a pipe located in the intake manifold.

The crankcase ventilation system has no serviceable components so no maintenance of the system is required.
