VW Valve Cover - Genuine VW 03H103429S

Product Information

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 VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW 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 VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly 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.
