Exhaust Emissions System - Crankcase Ventilation: Description

Crankcase ventilation system is used to recycle crankcase vapors back into the intake system for reburning. The system consists of an oil separator (which separates the oil from the vapors) and necessary connecting hoses. Metered orifices are also used in the hoses to control the amount of crankcase vapors being recycled into the intake system.
