Product Information

BMW Valve Cover and Components diagram for M5, Z8

An engine valve cover, or rocker cover, is a protective component that sits on top of an engine’s cylinder head, covering the valves and valve train components. It helps prevent oil leaks and protects the internal parts from dirt, debris, and other contaminants. In some newer applications, valve covers will also sometimes house the PCV Valve or part of the PCV system to allow engine oil crankcase pressure to be relieved properly.

• Age and Wear: Valve Cover Gaskets harden and crack over time, causing leaks or smells terminating from the engine
• Improper Installation: Uneven torque or poor gasket placement
• Material Fatigue: High engine temperatures can cause plastic or metal covers to warp or crack
• Blocked PCV Valve: Pressure buildup in the crankcase can damage the cover

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
