When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

On M52/S52-equipped BMWs, the factory crankcase ventilation (CCV) system is a notorious weak link. Between brittle plastic corrugated hoses that crumble from heat soak and an internal cyclone diaphragm prone to tearing, a failing CCV leads to massive oil consumption, vacuum leaks, and that dreaded "howling" whistle.

This kit addresses these issues with all new components and hardware. Both oil separator hoses, the cyclone separator itself, the mounting grommet, and the retaining bolts are included. Servicing this system is guaranteed to restore performance lost as a result of worn CCV components.

Kit includes:

Cyclone Separator/Crankcase Pressure Regulator Valve High Performance Silicone Breather Hose Return Hose Mounting Grommet Hex Bolt (3)

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!
