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.

The factory magnesium valve covers on the S65 engine are known for developing micro-porosity, corrosion, and persistent oil leaks over time. This material is highly susceptible to oxidation, leading to unsightly surface imperfections, weakened gasket channels, and sealing issues that a simple gasket replacement won't fix.

Upgrade to this high-strength aluminum valve cover set, engineered as a direct-fit replacement for your aging OEM covers. Unlike magnesium, aircraft-grade aluminum offers superior durability, enhanced heat resistance, and complete immunity to the corrosion issues that plague factory covers. Whether you're refreshing a high-mileage M3 or seeking long-term reliability, this upgrade ensures a leak-free, worry-free solution for your S65.

This valve cover set includes gaskets, bolts, and oil separators for a comprehensive replacement.

Features:

Eliminates the common porosity and corrosion issues found in factory magnesium covers.

Helps maintain optimal engine temperatures and enhances long-term reliability.

Gloss red finish provides a much-needed boost in engine bay aesthetic.

Designed for an OEM-like installation without modifications.

Reduces the risk of oil leaks, ensuring a proper seal.

Sputtering, no starts, or rough idle could be an indication of a failing or failed fuel pump. Also, if your gas gauge is not reading correctly, or not at all, it's probably the level sensor on this pump. Unfortunately, the level sensor is part of the pump assembly and must be replaced as a whole. This replacement Bremmen fuel pump is the perfect option to get your BMW back on the road without draining your wallet.

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.

GA6HP19Z Automatic Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This filter fits GA6HP19Z automatic transmissions. This will NOT fit the GA6L45R transmission. Please check your transmission to ensure it is the correct type. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

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. Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold
