This is the seal used to keep oil contained in the valve cover and the Valvetronic actuator on N62 engines. The original seal should be replaced if an oil leak is detected around the Valvetronic servo motor. There are two seals per motor - this is the thicker inner seal around the shaft. A thinner o-ring seals the motor base to the valve cover.
This is an OEM Valvetronic Motor Seal Ring for N62 engines manufactured by Elring Klinger - an original supplier to BMW for many gaskets and seals. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
