Don't neglect your motor mounts! The stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to shift. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

This is a replacement stock motor mount used on all M3s since 1995 and the Z4 M. It's also the standard motor mount for Z3 and E46 325xi/330xi models (left side). It can also used as an upgrade for non-M 1992-2006 E36 and E46 6 cylinder models because it's slightly stiffer to reduce flex and for a longer lifespan.

Sold per mount.

This motor mount / engine mount fits the following BMWs:
1995-1999 E36 BMW M3
2001-2005 E46 BMW 325xi 330xi (for left side only)

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 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.

Is your BMW showing signs of an oil leak? One of the most common causes is a failing oil pan gasket, a vital component that prevents oil loss and keeps your engine running smoothly. Over time, the gasket—typically made from metal with a durable rubber sealing bead—can wear out due to heat cycles, pressure fluctuations, and general aging. When the rubber bead deteriorates, it compromises the seal and results in leaks.

Ignoring an oil pan gasket leak can lead to more significant issues, such as low oil levels, reduced engine efficiency, and even serious engine damage. Addressing this problem early is crucial to maintaining your vehicle's performance and longevity.

For a reliable solution, choose Corteco. Known for their precision engineering and OE-grade materials, Corteco gaskets are crafted to deliver a perfect fit and exceptional durability. Trust Corteco to provide a high-quality replacement that ensures your BMW stays leak-free and running at its best.

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.

The rear main oil seal or crankshaft seals is one of the most difficult to replace. However, they often fail, and when they do, your car will be marking it's territory with little oil drops wherever you park. Apart from making a mess, it can also cause oil to come in contact with the clutch surface. Replace yours and keep your oil in your engine.
