This vent hose runs from both valve covers and returns oil vapor to the manifold on N62 engines and includes a check valve to keep oil vapor from returning to the cylinder head. The crankcase vent system is responsible for separating oil from the air inside the engine and air intake. Liquid oil is returned to the oil pan while oil vapors are sent to the intake manifold to be burned up during the combustion cycle. It's also known as a a PCV, CCV, oil separator, and a cyclonic separator system. Too much oil in the intake air lowers the effective fuel octane, leads to drivability issues, and causes increased emissions. A completely blocked CCV has the potential for very serious engine failure (hydrolock) if liquid oil ends up in the intake. Signs of a failing CCV include: whistling noises in the intake, blueish smoke in the exhaust, high oil consumption, and thick white or yellow gunk under the oil cap.

This is a N62 crankcase vent hose manufactured by Rein (CRP) Automotive - an original supplier to BMW for many engine components.
