Abstract
An intake manifold for an engine is provided that includes a housing having a passageway carrying blow-by gases from an engine crankcase. A valve body housing having a cavity is defined by a portion of the housing. The valve body housing has a vacuum side and a blow-by gas side. The blow-by gas side is in fluid communication with the passageway. A positive crankcase ventilation valve is disposed within the cavity and permits the blow-by gases to flow from the passageway through to the vacuum side when in an open position. A cap is preferably secured to the housing for sealing the positive crankcase ventilation valve within the cavity. Preferably an oil separator is also integrated into the intake manifold to separate the oil from the blow-by gases.
