Valve Cover

The valve cover is responsible for sealing the internal workings of the engines' top end. Most vehicles require a replacement gasket at some point or another and newer models have plastic valve covers that get brittle and crack with age.

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.

Features:

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

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

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.

Valve covers can crack or warp over time, leading to vacuum and oil leaks. This can cause check engine lights, a rough idle, and can make a mess, often covering the attached engine accessories in oil. If your valve cover has cracked or warped, we recommend replacing it with this aftermarket valve cover assembly. This replacement valve cover comes with new gaskets, BMW p/n 11129797205 and 11127617411, and new mounting hardware to attach the valve cover to the cylinder head.
