Positive Crankcase Ventilation: Description and Operation

Crankcase ventilation

Function
Crankcase ventilation regulates the pressure in the crankcase. Separation of oil from crankcase gases is integrated in the valve cover. The pressure is regulated via a valve integrated in the right valve cover. Crankcase gases are then led into the intake manifold via a water-heated connection nipple.
