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 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.

This is an OEM INA Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

This eccentric shaft is a vital component of your BMW's N55 Valvetronic system, responsible for precise control of valve lift. In the N55 engine, the Valvetronic system uses intermediate levers between the camshaft and lifters to adjust valve lift dynamically. These levers are actuated by this eccentric shaft, which is rotated by an electronically controlled motor under the direction of the engine computer.

Eccentric shaft failure is a common issue in N55 engines, often caused by inadequate lubrication due to extended oil change intervals. The most frequent failure occurs when the eccentric shaft gear wears down, leading to disengagement from the motor's worm drive. Symptoms include multiple fault codes, such as P1014 (Shaft Parity Error), P1017 (Shaft Sensor Plausibility), P1023 (Valvetronic Adjustment Range), and P10E1 (Valvetronic System No Travel Detected).

If your BMW is experiencing Valvetronic-related fault codes, a failing eccentric shaft could be the source of the problem. Opt for this premium direct replacement from Bremmen Parts to restore your Valvetronic system's functionality and ensure a durable, high-quality repair.

Oil venting and circulation continues to be a problem on BMW engines and now even more so on the turbocharged N54 and N55 engines. The existing stock system does a very poor job of separating fluid and vapor and this leads to an oily film or even small pools of oil throughout the turbos and intake. We're seeing a lot more 135 and 335 cars with drivability and performance issues because oil has sneaked by the ring seals and is coating the intake piping, intercooler, intake valves, and other critical areas. The problem is worsened with higher boost levels. Oil is excellent for lubricating moving parts but terrible when it gets into the combustion chamber, effectively lowering the octane rating and reducing performance. Our own shop has gone the extra step and offers media blasting of the intake valves to strip away the oily buildup we have seen.

Our shop also strongly recommends an oil catch can be installed in the line for the crankcase vent. The oil catch can traps oil as it leaves the valve cover and holds it in a canister. This catch can is located on the cooler side of the engine where the oil will condense easier and stay in the can. Whatever minimal vapors are left over in the oil is then vented back through the canister and into the intake where it is safe to be burned up in the engine or recirculated back through the system again. This is the way the system was designed! At each oil change simply unscrew the canister and empty the trapped oil with your regular used oil. The Burger Tuning oil catch can is the best we have seen so far. Installing one of these will avoid costly repairs in the future and help maintain your boost and performance. It's one of the smartest modifications you can make because it demonstrates a well-thought out tuning strategy and care for the condition of your engine.

The BMS Oil Catch Can is made from aluminum and with a stealthy black anodized finish. It installs on the cooler side of the engine with a dedicated bracket and new oversized vent lines. The location is key as heat will evaporate the oil and send too much vapor back into the engine (where cooler air will turn it back into fluid). The BMS OCC also has a factory-like appearance. Since BMS designed their catch can from scratch they can guarantee it fits and performs correctly for the N54/N55 engine, unlike other catch cans on the market that are poorly retrofitted from other applications and under-sized for the N54 engine.

Note: Since the crankcase vent system is considered part of the overall emissions system, installing this may be a violation of local, state, and federal laws. While exemptions are made for track/race and off-road use, check with your local state inspection facility on using this in street-driven vehicles
