This is an OEM INA tensioner pulley, also known as the adjusting pulley and lower pulley. This pulley is mounted on the belt tensioner near the center of the belt assembly. The upper and lower pulleys are known to be the primary sources for 'belt squealing'. This pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

OEM Schaeffler (INA, LuK, & FAG) is an engineering company that focuses on high-performance, precision manufacturing. With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.

Most of the pulleys on your BMW engine are plastic, which become brittle and frail over time and from engine bay heat. A failed pulley could leave you stranded which is why it is vital to inspect the pulleys during routine maintenance. This is an aluminum version of the stock water pump pulley used on the M50/M52/M52TU/M54 engine in the E36, E46, Z3, Z4, and other models. It uses the same hardware and the original belt as the stock plastic pulley. But the aluminum will last much longer.

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.

As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

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 from the 2007 model year and includes:

  • 11127582245 - N52 valve cover gasket set
  • 11127552280 - N52 eccentric shaft sensor seal
  • 11127559699 - N52 Valvetronic gasket

2007 and later N51/N52 engines do not need replacement valve cover bolts, unless the bolts are actually broken off or missing. Unlike the 2006 aluminum hardware, the later parts are steel and not 1-time use.

These are all OEM or OE 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 . The seal around the sensor can fail and allow oil to blow out from under the cam cover. Oil can then leak into the sensor itself and cause it to 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:

Maintaining the peak performance and reliability of your BMW N52 engine is essential for a smooth and enjoyable driving experience. One of the most effective ways to achieve this is by replacing critical components like the valve cover, crankcase vent hose, angle connector with heating element, and cylinder sleeve. In this article, we'll delve into the numerous benefits of upgrading these vital parts, ensuring your BMW N52 operates at its best. Optimized Engine Performance: Replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve enhances your BMW N52's engine performance. The valve cover plays a crucial role in sealing the engine, preventing oil leaks and ensuring optimal valve operation. When you upgrade these components, you reduce the risk of performance-robbing oil leaks and maintain precise valve timing, resulting in improved horsepower and torque. Enhanced Reliability: Reliability is paramount for any BMW owner. These components, when aged or damaged, can lead to severe engine issues. By replacing them, you significantly reduce the likelihood of unexpected breakdowns or costly repairs, ensuring your BMW N52 engine runs smoothly and reliably for years to come. Improved Fuel Efficiency: An efficiently operating engine not only performs better but also consumes less fuel. The replacement of these components leads to better combustion, reduced emissions, and ultimately improved fuel efficiency. This means fewer trips to the gas station and a lighter environmental footprint. Reduced Maintenance Costs: Regular maintenance and repairs can add up over time. By proactively replacing the valve cover, crankcase vent hose, angle connector, and cylinder sleeve, you mitigate the risk of more extensive engine damage that could lead to expensive repairs down the road. In the long term, this can translate into significant cost savings. Extended Engine Lifespan: The longevity of your BMW N52 engine is directly tied to the quality and condition of its components. When you invest in high-quality replacements, you're effectively extending the lifespan of your engine. This not only preserves the value of your BMW but also allows you to enjoy its performance for years to come. Precise Temperature Control: The angle connector with heating element is vital for maintaining optimal engine temperature, especially in cold weather. A malfunctioning or worn-out connector can disrupt temperature control, affecting engine performance. Replacing this component ensures consistent and precise temperature management. Customized Upgrades: When replacing these components, you have the opportunity to choose high-performance or specialized alternatives, allowing you to customize your BMW N52 to your preferences. Whether you prioritize power, efficiency, or specific driving conditions, there are options available to tailor your engine's performance accordingly. Included in the BMW N52 Valve Cover & PCV Valve Refresh Kit: 6 Cylinder Sleeves 1 Alternator Mounting Screw Set 1 Angle Connector with Heating Element 1 Valve Cover - Gasket Included 1 Crankcase Vent Hose

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.

As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.

Over time, your engine timing components begin to wear out. Tensioners weaken, chains can stretch, and timing chain guides can wear down. All of these lead to the possibility of the timing chain jumping teeth on the sprockets, causing your timing to shift. This could result in rough idle and reduced engine power, or even complete engine failure. Prevent damage to your engine with new timing components, such as this IWIS timing chain tensioner. Note, we recommend replacing timing components every 100K miles, or sooner, depending on the condition of the timing components.

What's better than using new crank bearings in your next engine build? WPC-treated bearings! What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or crank service!
