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. Includes new mounting hardware

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 has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. Don't forget to order a valve cover gasket to make your separator change easier.

A damaged, leaking, or missing vacuum check valve can lead to a range of engine performance issues. As a critical component in the vehicle's vacuum system, the check valve ensures proper air flow and pressure regulation within various engine systems. If compromised, it can cause erratic idling, poor acceleration, or rough engine performance. Additionally, a malfunctioning vacuum check valve may trigger the check engine light and could cause your vehicle to fail an emissions test due to improper control of exhaust gases. Timely replacement of a faulty vacuum check valve is essential for maintaining engine efficiency, preventing further damage, and ensuring compliance with emissions regulations.
