Genuine BMW Oil Separation & Breather System for BMW 5 Series G30 (2017+)

Clear BMW chassis

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.

BMW part number 11158601619 is a genuine OEM crankcase ventilation intake pipe designed for specific BMW models. This component is integral to the engine's positive crankcase ventilation (PCV) system, directing blow-by gases from the crankcase back into the intake manifold for combustion. This process reduces emissions and helps maintain engine efficiency. Compatible BMW Models: BMW 750i (G12): 2016–2019 BMW 750i xDrive (G12): 2016–2019 BMW M550i xDrive (G30): 2018–2019

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!
