An intake manifold drain assembly of an engine comprises a drain tube connected to a bottom of a manifold chamber; an oil separator connected to an engine block; and a controlled check valve connecting the drain tube to the oil separator and configured to allow liquid and gas in the manifold chamber to flow into the oil separator and control a gas flow passing the controlled check valve below a threshold flowrate.

Intake manifold drain assembly of an engine

An oil pan in an engine assembly comprises a housing including a bottom wall and a sidewall and an oil drain tube. The oil drain tube includes a tubing wall and a portion of the sidewall and is integrally formed with the housing.

Oil pan in an engine assembly and a crankcase ventilation system

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.
