Abstract
An engine assembly may include an engine structure, an intake assembly and a cylinder head cover assembly. The engine structure may define a combustion chamber and a crankcase in communication with a fresh air supply. The intake assembly may be in communication with the combustion chamber. The cylinder head cover assembly may be fixed to the engine structure and may include a cover member defining a positive crankcase ventilation chamber and a separator coupled to the cover member. The separator may define an inlet providing communication between the crankcase and the positive crankcase ventilation chamber. The cylinder head cover assembly may include a first outlet flow path in communication with the intake assembly and a second outlet flow path in communication with the intake assembly. A first valve may be located in the first outlet flow path.
