This tube runs from the oil separator to the lower dipstick tube.

 

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.

If your rocker arm rollers have failed, this can lead to extreme camshaft damage, requiring the camshaft to be replaced.

The camshaft position sensor is essential for assisting the engine DME by monitoring the camshaft's position. The data from this sensor is key to optimizing ignition timing and ensuring smooth engine performance. Often referred to as the CMP sensor, this component is crucial for the overall functionality of the powertrain. A failing camshaft position sensor can cause a range of issues, including engine stumbling, hesitation during acceleration, power loss, and even starting difficulties or complete failure to start.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. This oil pan baffle by AAF keeps the oil at the pick up better than others on the market. Baffling the oil pan is extremely important. Under racing and track conditions, oil can move in the oil pan enough to cause extended moments of oil starvation. This can cause premature, and in some cases immediate, engine failure. The pan features a tight fit to keep oil from exiting under braking or cornering. A must have for all track cars.
