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 this and all the other components of the oil separator system 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.

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.

The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy. When malfunctioning, your MPG and performance can suffer. Replaced fairly easily, you can restore your performance and mileage quickly. Be sure to add anti-seize on the threads to prevent it from becoming a permanent part of the exhaust. Regularly scheduled maintenance as these tend to fail slowly.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. This is a Meyle oxygen sensor for BMW's with the N52, N54, and N55 3.0L engines. This 560mm bank 1 oxygen sensor is mounted after the catalytic converter. As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!
