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.
BMW E46 Crankcase Pressure Regulator Valve | S54 3.2L Engine is a crucial component that ensures proper crankcase ventilation by regulating oil vapor flow into the intake manifold, preventing excessive oil consumption and buildup. Designed specifically for BMW E46 models with the S54 3.2L engine, this valve helps maintain engine efficiency and performance. BMW engines are known to experience oil separator freezing in cold weather if not fully warmed up, which can lead to howling noises and oil leaks. To ensure a thorough repair, replacing the valve cover gasket when changing the separator is highly recommended.
Protect your BMW's engine from excessive oil consumption and leaks by replacing a failing crankcase pressure regulator valve with this premium-quality replacement.

A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes.
If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage.
Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold.
