BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW Z4 M Roadster S54 (2003-2008)

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.

When these gaskets leak you'll start to smell oil burning when the engine is hot. Also everything downward from the top of the engine becomes coated in a greasy film. The valve cover gasket keeps all of the motor oil inside your engine. Your valve train and lifters get soaked with oil to keep everything lubricated. If the valve cover fails, engine oil seeps and leaks out, running down and burning on the block or cylinder head. Replace it and keep your engine compartment clean and tidy with all the engine oil in the motor. If you are removing your S54 valve cover for valve adjustment, inspection or repairs, you can now get all the gaskets you need in one box. Included are Valve cover gasket Spark plug seals Nut seals Grommets Copper sealing washers

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem.

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.
