1.5L REVOTORQ ENGINE 82 F. BLOW-BY VENTILATION SYSTEM Blow By Circuit Schematic Layout Description In order to reduce the blow by gas emission, the blow by gas is directed to the oil separator which separates the oil from the blow by gas and allows the air to pass to the air filter and oil to the sump. Blow by gases are drawn from cylinder head cover and crankcase. The formation of excess blow-by can form sludge and acids. The sludge can clog oil lines and starve the lubrication system. The blow-by system consists of the following components. 1. Oil Separator and hoses Components A.
