BMW's Single-VANOS M52 and S52 engines were equipped with plastic valve covers from the factory. Nearing thirty years post-production, this material choice has proven to be problematic. Due to years of exposure to extreme engine temperatures and chemical-rich engine oil, these plastic valve covers will eventually warp. This results in a valve cover that will not seal, requiring a complete replacement of both the plastic valve cover and associated gaskets.

To remedy this, many enthusiasts opt to swap for the magnesium valve cover found on M50 and S50 engines. Unfortunately, magnesium is no less resistant to heat-induced warpage than plastic.

Thankfully, Bremmen Parts is aware of these issues and has created an exact-fit, high-quality performance replacement for all Single-VANOS M52 and S52-equipped BMWs. This cover features durable aluminum construction, which eliminates the warping issue found on OE plastic and magnesium valve covers. Unlike the OE magnesium cover upgrade, Bremmen's aluminum cover retains the forward oil fill location found, allowing you to retain your existing engine beauty cover.

Whether you're replacing a warping plastic cover or preemptively replacing this failure-prone component, Bremmen has you covered with a direct-fit aluminum valve cover upgrade.

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, throttle body gasket, and a new intake boot to make your separator change easier and more comprehensive.

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.

This item is 70mm Diameter. Please check the diameter before ordering.
