Genuine BMW Oil Separation & Breather System

Every car has a crankcase vent system that is supposed to suppress oil from making it into the intake ports and combustion chamber. A good functioning system will separate oil from the atmosphere and return it to the oil pan (or collect it in a catch can) while allowing the leftover vapors to burn in the combustion chamber or recirculate through the system. This has always been known as a PCV system (Positive Crankcase Ventilation) but BMW has several other names for it - oil separator, crankcase vent (CCV), and cyclonic separator. Failures in the system will allow raw oil to enter the intake and eventually into the engine itself which can have disastrous effects on engine performance and longevity. As emissions regulations on oil and gas venting have gotten more stringent the PCV systems have gotten more complex and failure prone. And because the CCV is intertwined with other systems you could experience rough running, loss of power, higher oil consumption, misfiring, stalling, or other annoying issues. There is no replacement interval for these so we recommend inspecting your crankcase vent system as part of your regular maintenance routines. Symptoms of a bad crankcase vent are: whitish or yellowish film on the underside of the oil cap, whistling/squealing noises (not caused by a belt), suction on the oil cap that makes it hard to unscrew, large amounts of white smoke from the exhaust, and excessive oil consumption.

The crankcase breather, or also commonly called the PCV or oil separator, allows the crankcase to expel air without losing any oil. When failing, the PCV can cause misfires and a rough running commonly experienced at idle. This kit allows you to service your breather system and keep your vehicle's emissions system in top shape and running great.

BMW's B58 engine has been great, but one major weakness is the PCV valve. As stated by BMW, "The PCV's rubber diaphragm seal may fail, causing insufficient engine oil separation. As a result, the engine may emit blue/white smoke from the exhaust tailpipes, shudder during operation, and/or run with reduced power (limp mode). At idle, a high-frequency whistling noise may be heard in the engine compartment, and the malfunction indicator lamp (MIL) may also illuminate." If your BMW is experiencing these issues, there is a very likely chance your PCV has failed. If so we recommend replacing your PCV with this Genuine BMW repair kit! Don't want to spend over $200 for this fix? We also offer T#23980285 which also replaces this valve but at roughly 1/10th the price!

The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or solid oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create a oil sludge condition that is impossible to clear. Thankfully, the CCV is replaceable on the early N52 engines (2006) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.
