Crankcase ventilation

Crankcase ventilation


The engine crankcase ventilation is completely enclosed. The ventilation consists of a nipple by the valve cover from which a hose is connected to the hose between the mass air flow sensor and the turbocharger.

The hoses and their connections are dimensioned to provide adequate escape of the engine crankcase exhausts under all operating conditions. The crankcase exhaust emissions are directed via a valve in the valve cover to the hose between the mass air flow sensor and the turbocharger, where the gases are mixed with the induction air and combustion then occurs in the engine.
