An engine system comprises an intake manifold including a manifold body downstream of an intake port and having a first through-aperture and a second through-apertures spaced apart from the first through-aperture on the manifold body; a positive crankcase ventilation (PCV) system including a first PCV branch and a second PCV branch communicated fluidly with the first through-aperture and the second through-aperture of the manifold body, respectively, and configured to route a blow-by gas in a crankcase to the intake manifold; and a variable valve assembly to regulate a flow passing through the first or second PCV branches.

A torsional vibration damper mounted at a crankshaft of an engine is provided. The torsional vibration damper comprises a hub having a first mounting surface and a second mounting surface opposite to the first mounting surface, an inertia ring and an elastomer element disposed between the hub and the inertia ring. The hub includes a first mounting hole configured to receive the crankshaft, and at least one slot spaced apart from the first mounting hole. The slot is configured such that a center-of-gravity of the torsional vibration damper is offset from a central axis of the crankshaft.

An engine assembly is provided with an intake manifold having a manifold body downstream of a fresh air intake port. The manifold body has a wall defining first and second apertures spaced apart from one another. A positive crankcase ventilation (PCV) device is provided with a PCV pipe having a first end in fluid communication with a crankcase and a second end connected to first and second PCV branches. The first and second PCV branches are in fluid communication with the first and second apertures. A method is provided and directs a first portion of gases from the crankcase to the first aperture via the PCV pipe and the first PCV branch, and directs a second portion of gases from the crankcase to the second aperture via the PCV pipe and the second PCV branch.

A system for an internal combustion engine is provided. The system includes an oil pan, a pick up tube; and a spacer. The spacer is positioned vertically above a static oil level and secured to a surface of the oil pan. Further, the spacer may include an opening that may communicate with oil when the oil is in a tilt orientation.
