Abstract
An engine assembly includes an engine block at least partially defining a combustion chamber and a crankcase volume. The engine block defines an opening in fluid communication with the crankcase volume. An air-oil separator is mounted to the engine block at the opening and is configured to separate oil from blowby gasses flowing from the crankcase volume through the air-oil separator. A method of venting an engine crankcase volume is also included.
