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.

This fuel tank hose runs from the filler neck to the inlet of the fuel tank. Due to years of exposure to water, salt, dirt, and general road debris, this hose is commonly rotted out causing a leak when filling the fuel tank.

If your hose is leaking, replace it with this high-quality, exact-fit piece from Bremmen Parts.

The solenoid is used to fasten the camshaft adjuster to the camshaft, and also controls the flow of oil into both camshaft adjusters. The central valve/oil control valve is crucial to proper VANOS operation.

If your central valve is worn, clogged, or was removed for camshaft service, replace it with this high-quality, exact fit piece from Bremmen Parts.

BMW N20 N52 N55 Timing Chain addresses the common issue of timing chain stretch and rattling over time. Although BMW designates the timing chain as a lifetime part, many enthusiasts choose to replace it preemptively. Turner Motorsport offers this direct-fit replacement for those needing to replace a worn or damaged timing chain without opting for a full kit.

• Direct Fit Replacement: Perfect for replacing a stretched or broken timing chain.
• High-Quality Construction: Ensures durability and reliability in maintaining engine timing.
• Ease of Installation: Designed to fit precisely without requiring additional modifications.
• Ideal for Maintenance: A practical choice for enthusiasts who prefer to change the timing chain independently of a full kit.

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 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.
