BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW X5 M S63 4.4L

Gaskets are key to a properly running and clean engine. They obviously prevent fluid leaks but they're also critical in keeping air either in or out... Air leaks after the air flow meter, also known as vaccum leaks, can induce lean running conditions, fault codes, and poor running conditions. Other seals and gaskets are designed to keep air in. With the sensitivity of OBD systems, leaks will lead to fault codes very quickly which can be tough to diagnose and prevent you from passing state inspections.

We insist on Original BMW or OEM gaskets whenever possible.

Maintaining proper oil levels in your engine is crucial for peak performance. Undetected leaks can cause your oil to drop to dangerously low levels between oil changes, leading to severe engine damage.

One common culprit for oil leaks is the valve cover. Over time, exposure to extreme temperature fluctuations can wear down the gaskets, causing them to fail. Prevent oil leaks and protect your engine by replacing these vital components.

Athena-SCE's gasket body is composed of Motorgasket, a reinforced material developed by Athena's R&D department. This consists of a steel core covered with two layers of asbestos-free aramid fibre and offers excellent thermal and mechanical resistance without compromising its ability to adapt to mating surfaces. To ensure maximum sealing under all conditions, a silicone bead is also applied to critical sealing areas, such as oil and coolant passages. The AISI 304 stainless steel cooper rings bite into the aluminum head, providing maximum sealing around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2 bar boost. Please be aware that the gasket should be 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm. Before installation, it is crucial to have the mating surfaces of the cylinder head and block professionally cleaned and resurfaced to ensure they are completely flat. Sold as a set - Includes Bank 1 and Bank 2 Gaskets Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant. Install the Cut Ring gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed. It is recommended to not use any additional sealant on the MLX gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.

Keeping the oil inside your engine is extremely important to performance. Between oil change intervals, your oil can dip to dangerous levels if there is a leak you are not aware of. The valve cover is an extremely common place for leaks to begin. Years of exposure to extreme temperature change degrades the gasket and can cause failure. This gasket will keep oil where it is supposed to be, inside your engine, not on your driveway. Lifters and rockers will stay properly lubricated and your vehicle will not have that hot oil smell. Often difficult to pinpoint, your valve cover gasket is the first place to look when your vehicle starts to leave oil spots. Trouble trying to track down your leak? The easiest way to do so is by cleaning your engine, then examining for leaks.
