Mercedes O-Ring - Genuine Mercedes 0189979045

Product Information

A camshaft seal is a rubber or silicone ring located on the top of the cylinder head near the back of the engine, designed to prevent engine oil from leaking out; a failing camshaft seal will most noticeably manifest as visible oil leaks around the back of the engine, sometimes accompanied by smoke from the engine bay when the leaking oil comes into contact with hot exhaust components

• Visible oil leaks: The most obvious sign, usually seen on the back of the engine near the valve cover.
• Smoke from the engine bay: Oil leaking onto hot exhaust manifolds can burn off, producing smoke.
• Oil residue on the engine: Even small leaks can leave noticeable oil stains on the engine.

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

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