BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW E90 M3 S65 4.0L

Clear BMW chassis

Please ensure your correct model is selected

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.

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 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.

If your valve cover is leaking oil or a bad seal is causing vacuum issues and check engine lights, we recommend replacing your seals with this complete valve cover gasket kit! This kit includes all of the main gaskets and o-ring seals used by BMW to seal your valve cover to the cylinder head. Included: Victor Reinz Left & Right Valve Cover Gaskets Genuine BMW Oil Separator Seal O-rings - Two Per Valve Cover Genuine BMW Crankshaft Position Sensor O-Rings - Two Per Valve Cover URO Spark Plug Tubes w/ Gaskets If you are not replacing your valve cover, we also recommend inspecting the grommets found on the valve cover bolts. Over time these can compress or split, leading to insufficient sealing of the valve cover to the cylinder head due to a lack of pressure. BMW does not offer these grommets separately from their individual valve cover bolts, but NRW Design came in clutch with their Silicone Valve Cover Grommet Kit.
