BMW Engine Parts for BMW Z Series E85/6 (2003-2008)

The VANOS system on your N51, N52, and N54 engine controls the valve timing inside the engine. The system is hydraulically operated based on instructions from the engine computer. It's very complex and BMW has not yet perfected the system. The VAN0S solenoid is the actuator that takes instruction from the ECU and activates the VANOS unit on the front of the engine. When the solenoid is failing (or failed) you can end up with a rough running engine, misfires, bad fuel economy, lack of power, and more. It should trigger multiple fault codes and a check engine light for misfires, camshaft control, VAN0S solenoid, boost pressure control, and maybe others. It's important to thoroughly troubleshoot fault codes but VAN0S solenoids are a known issue with these engines.

The VANOS solenoids are located on the front of the engine and may be replaced without removing many other components. In some cases, you may be able to remove the suspect one, clean it, reinstall, and reset your fault codes. If your fault codes come back it's a strong indication that a replacement is required. Or you can buy the new solenoid and replace instead of doing the work twice.

VANOS solenoid for the intake and exhaust are the same part number. Order 2 if you want to replace them both.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

We recommend replacing the solenoid sealing gaskets as well when replacing the solenoid. You can find these under T#363393

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.

This valve cover kit fits the following BMWs:
2006 E90 BMW 325i 325xi 330i 330xi - Sedan
2006 E91 BMW 325xi - Wagon
2006 E60 BMW 525i 525xi 530i 530xi
2006-10/2006 E85 BMW Z4 3.0i Z4 3.0si

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).
