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.

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.

This is an OEM INA Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower 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).
