Crankcase Ventilation System

Engine oil sump is sealed. Couples oils and break into the crankcase when the engine gases are vented through a wire separator in the intake system of the engine and burned it.

With the high vacuum in the intake system (eg, idling) gases are drawn from the crankcase and the low vacuum (accelerator pedal fully depressed), they are forced out of the crankcase elevated pressure in it. When deterioration of the engine crankcase breaks large number of gas and the pressure in sump increases, so some flow back into the engine at all operation modes. On the part of the engine on timing case cover, set the pressure control valve that controls the flow of crankcase gases.

Crankcase ventilation system does not require maintenance. To test your system, check the crankcase ventilation hoses for damage.
