Valve Cover

Introducing our newest upgrade for your E36: a full billet aluminum valve cover engineered to eliminate factory and aftermarket valve cover issues. If you're familiar with our new Turner Motorsport products for 2023 and 2024 you can tell that our engineering team at Turner has a focus on older chassis, especially the E36.

Our valve cover is designed to fit some of the best engines BMW ever came out with, single vanos M50/M52 and S50/S52. Not only are these great motors in general and deserve an upgraded valve cover but they are also prime for boosting. When adding boosting you will be introducing heat which can wreak havoc on your ignition system and make your factory valve cover extremely prone to failure.

The reality of the M5x/S5x motors is that the plastic valve covers are sub-par and the magnesium versions are no longer available from BMW and even those can even warp. You can end up replacing your valve cover time and time again dealing with issues if you prefer but the option is here for you. The last valve cover you buy for your E36.

Our engineers designed this valve cover with experience and personal passion that offers a plethora of benefits for your M5x/S5x motor. Whether you plan to cherish your E36 for years to come or envision a turbocharger upgrade, our valve cover is the ultimate solution. It boasts rugged durability and brilliant aesthetics, ensuring it's a perfect fit for any enthusiast.

Featuring full 6061 billet construction and a type-3 hard coat finish, our valve cover is built to endure extreme conditions and rigorous use. Whether you opt to retain your factory PCV setup or upgrade to a catch can for racing purposes, the cover provides dedicated, direct-fit ports for both configurations.

The base kit includes all the necessary components for a seamless installation. Additionally, the description provides part numbers for optional replacements and add-ons, ensuring you have everything you need to complete your install.

Over time, the factory valve cover hardware on M50, M50TU, M52, M52TU, M54, S50 (US), and S52 engines is subjected to continuous heat cycling, oil vapor, and moisture, causing original cap nuts to oxidize, corrode, or thread-strip during routine maintenance. Our Polished Valve Cover Cap Nut serves as a direct replacement designed to address these common failure points while improving upon overall engine bay aesthetics.

Because maintaining precise gasket compression is critical to preventing oil leaks, these cap nuts and washers are machined directly to OE-style dimensions. This exact fitment allows for direct compatibility with original and replacement valve cover studs (see T#55317643) and ensures the hardware can be torqued precisely to OEM specifications without guesswork. Manufactured to grade 8.8 structural strength standards, the hardware maintains the necessary clamp force required under normal and high-performance engine operating conditions.

To resist corrosion, both the cap nut and washer undergo an electroless nickel plating process during production. Unlike standard zinc coatings that dull or rust over time, electroless nickel provides a uniform layer of corrosion resistance that withstands long-term chemical exposure and extreme temperature swings while giving the hardware a polished, high-end appearance. Each cap nut assembly includes an OE rubber washer seal, ensuring a tight, leak-free barrier that prevents oil from escaping through the mounting studs.

Upgrade your BMW's engine bay with the Aluminum Valve Cover 11127552281M to eliminate leaks and add a touch of style. This high-quality valve cover ensures a secure seal, preventing leaks and enhancing the aesthetic appeal of your BMW.

• Aluminum Valve Cover for BMW
• Eliminates leaks for improved engine performance
• Adds style to the engine bay
• High-quality construction for durability and reliability

From the factory, BMW S65 valve cover bolts feature integrated non-serviceable grommets. These rubber seals tend to weaken, becoming brittle after years of heat and oil exposure. Replacing these bolts and integrated grommets can total over $280

To address this issue, NRW has developed a solution: a silicone replica of the factory rubber grommet, boasting a superior heat resistance of 170 degrees Celsius compared to the original's 120 degrees Celsius. Each kit contains 26 grommets, enough to service both valve covers.

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.
