ENGINE 64 B. Blow By System : Blow By Circuit Schematics Layout : In order to reduce the blow by gas emission, the blow by gas is directed to the intake manifold through the oil mist separator which separates the oil from the blow by gas and allows the air to pass to the intake manifold. Blow by gases are drawn from crankcase and cylinder head cover. Components : a) Oil Mist Separator : The oil mist separator separates oil from the blow by of the engine and sends it back to engine oil sump. The remaining air and other gases are sent to the inlet manifold. There is a spring loaded diaphragm valve provided on the oil separator outlet which prevents the flow of excessive blow by gasses from the oil separator to the inlet manifold in case the air filter is chocked and high suction starts acting on outlet port of oil separator. 1.

Replace the assembly if there is any leakage or found defective.
