Abstract: A PCV device for recirculation of crankcase air has a structural member with a tubular, substantially linear internal flow passage characterized by a length and diameter with a ratio of length to diameter that attenuates noise and acts as a restrictive orifice to at least partially control flow volume therethrough. A PCV system for an engine includes a structural member as described above placed in fluid communication with a passage member to partially form a flow path between an interior portion of an engine crankcase and an air intake portion of the engine. The flow path has an absence of any flow restriction with a diameter smaller than the diameter of the structural member.
