Engine Emissions

The engine emission control system reduces the level of hydrocarbon emissions released to atmosphere from the engine. The engine emission control system consists of an engine vent oil separator and positive crankcase ventilation valve located on the top of the of the camshaft cover. Piston blow-by gases are drawn through the breather into the engine air intake. The resultant depression in the engine oil pan, front covers, camshaft carrier and engine vent oil separator reduces the load on the joint seals in those areas.
