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 engine oil level sensor tracks the oil level in the engine's oil pan, sending real-time data to the ECU (Engine Control Unit). This vital information ensures the engine has the right amount of oil for proper lubrication. Commonly featured in modern vehicles, the oil level sensor acts as an essential safeguard against low oil levels, helping prevent potential engine damage.

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.

Resistant to oxidation and chemical exposure for a long-lasting clean look.

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.

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, 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 includes gaskets, bolts, and the oil separator 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.

Resistant to oxidation and chemical exposure for a long-lasting clean look.

The valve cover gasket seals the valve cover to the cylinder head, preventing oil leaks and maintaining engine integrity. Over time, exposure to high engine temperatures causes the gasket's rubber construction to degrade, leading to significant oil leaks. This often presents as a noticeable "burning oil" smell at idle, caused by oil dripping from the valve cover onto the hot exhaust manifolds.

If your valve cover gasket is failing, restore proper sealing and prevent further leaks with this premium OE replacement from Bremmen Parts.

Note: This gasket is designed for the left-side cylinder bank (cylinders 1-4). For the right-side cylinder bank (cylinders 5-8), see T#36913369.

Ditch the failure-prone plastic housing with this upgraded aluminum oil filter housing, built for strength, reliability, and peace of mind.

The factory plastic housing is a well-known weak point and a common source of oil leaks on BMW B58 engines. Once leaks develop, replacement is the only solution. Left unchecked, even minor oil loss can lead to premature engine wear, or in the worst cases, catastrophic failure.

This upgraded housing not only solves the problem with a durable aluminum construction, but also comes complete with caps and seals for a straightforward, hassle-free installation.

Protect your engine from unnecessary risk, upgrade your filter housing, and ensure a leak-free, long-lasting seal.
