Abstract: A PCV system includes a PCV valve configured to be inserted into a port formed on a mating component of an engine and regulate a flow of blow-by gases from a crankcase to an intake manifold. A PCV line includes a first end, and a second end configured to fluidly couple to the air intake manifold. A PCV valve cap is coupled to the PCV line first end and configured to further couple to the mating component to secure the PCV valve in the port and establish a fluid coupling with the mating component. The PCV valve is separate and distinct from the PCV valve cap such that a disconnection of the fluid coupling between the PCV line first end and the mating component separates the PCV line from the PCV valve such that the PCV valve no longer regulates flow through the PCV line into the intake manifold.

Abstract: A positive crankcase ventilation (PCV) system for an internal combustion engine includes a forced air induction system configured to supply air to the engine, a PCV line configured to fluidly couple between a crankcase of the engine and a clean side air duct of the forced air induction system, a make-up air (MUA) line configured to fluidly couple between the crankcase and the clean side air duct, and an inlet valve disposed in the forced air induction system. The inlet valve is configured to be controlled selectively move between an open position and a closed position to vary an air restriction in the forced air induction system and generate a vacuum. The vacuum draws blow-by gases from the crankcase through the PCV line and into the air induction system when the engine is under either naturally aspirated or boosted conditions.
