General Description Buick Century VI

Mechanical 1 illustration

The crankcase ventilation system is used to consume crankcase vapors (1) in the combustion process instead of venting them to atmosphere. Fresh air from the throttle body is supplied to the crankcase, mixed with blow by gases and then passed through a positive crankcase ventilation (PCV) valve (3) into the intake manifold.
