Abstract: Apparatuses, systems and methods are disclosed including apparatus for a ventilation system for supplying air to a crankcase of an internal combustion engine. The apparatus can optionally include a housing, an air filter, a lid and a pressure relief valve. The housing can form a cavity and having an inlet and an outlet therein. The inlet communicates with the cavity and is offset from a centerline axis of the housing. The air filter can be received by the cavity. An outer circumference of the air filter can be oriented at an angle that is substantially tangent to the inlet. The lid can be attachable to and removable from the housing for selectively accessing the air filter. The pressure relief valve coupled to the housing and in fluid communication with the cavity.
