Not only will this kit stop most E90 oil leaks, it's the perfect addition for ignition coil or spark plug replacement! Oil leaks - and the damage they can cause - seem to be the worst annoyances on these cars. The biggest source of an oil leak is from the valve cover, followed by the oil filter housing, Valvetronic seal, camshaft seals, and the eccentric shaft sensor seal. Once the oil leaks, and if ignored for an extended time, the oil will contaminate vital electrical sensors. This is especially the case with ignition coils and also the eccentric shaft sensor on the Valvetronic shaft at the top of the cylinder head. During any ignition coil and spark plug replacement take a close look inside for any oil pooling at the bottom. We have been seeing valve cover oil leaks as soon as 40,000 miles. We look for oil leaks on every E90 that comes into our shop.

We have put together this package of valve cover gaskets and other related gaskets and seals for you to fully overhaul the N52 valve cover and put a stop to those pesky oil leaks. This package has the replacement parts for N52 engines built up to 10/2006 and includes:
 

• 11127581215 - N52 valve cover gasket set
• 11120409288 - N52 aluminum valve cover bolts (1-time use only, not re-usable)
• 11377516302 - N52 Valvetronic gasket
• 11127528242 - N52 eccentric shaft sensor seal

These are all Genuien BMW parts. Replacement of these gaskets and seals is straight-forward but a long process. BMW dealers typically charge for over eight hours of labor. If you have replaced spark plugs before you should be capable of this repair. In addition, there are several other parts to replace while you're in the vicinity: camshaft sensor o-rings, oil filter housing profile gasket, VAN0S solenoids, and the eccentric shaft sensor. These other parts, except the eccentric shaft sensor (see below), are replaceable without removing the valve cover but are more easily accessed during the valve cover work.

Eccentric Shaft Sensor: This is the position sensor that relays the eccentric shaft's position back to the DME. It's located at the front of the engine and is only accessible with the valve cover off. Over time the seal around the sensor comes loose and oil is allowed to blow out of the cam cover and it eventually finds its way into the sensor (which will eventually fail). Without a functioning sensor your E90 can experience poor running, hesitation, poor performance, jerky shifts, and sluggish response. It's easy to check and see if oil has accumulated inside the sensor: unbolt the engine trim cover (the outer cover with the BMW roundel), unplug the sensor, and look inside. If oil is present inside or even around the sensor itself, plan on replacing this sensor during your next ignition coil, spark plug, and/or valve cover gasket work.
