These models use the updated N63TU engine, not the original N63 engine that came out in 2009. Note the years as the valve covers were re-designed on the later models. This kit contains all Genuine BMW parts and is what BMW recommends when replacing the N63TU oil separators (crankcase vent) system.

The N63TU crankcase vent valve 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.

Also clean the vent pipes and connecting lines in the rest of the CCV system or replace all the upper lines while you're in there. BMW makes a connector seal kit when servicing the existing hoses (see below).

This is a Genuine BMW N63TU oil separator kit with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
