Engine Vent Oil Separator

Piston blow-by gases are drawn through the engine vent oil separator into the engine air intake manifold and added to the air charge. The depression caused by the engine air intake draws gasses from the crankcase, through the engine vent oil separator and the hose into the intake manifold.

The resultant depression in the oil pan, front covers and cylinder head covers reduces the load on the seals in those areas. Engine oil is drawn into the engine vent oil separator and is collected on angled plates. The oil collects on the plates and falls back to the oil pan through a hole in the cylinder block.
