BMW's Single-VANOS M52 and S52 engines were equipped with plastic valve covers from the factory. Nearing thirty years post-production, this material choice has proven to be problematic. Due to years of exposure to extreme engine temperatures and chemical-rich engine oil, these plastic valve covers will eventually warp. This results in a valve cover that will not seal, requiring a complete replacement of both the plastic valve cover and associated gaskets.

To remedy this, many enthusiasts opt to swap for the magnesium valve cover found on M50 and S50 engines. Unfortunately, magnesium is no less resistant to heat-induced warpage than plastic.

Thankfully, Bremmen Parts is aware of these issues and has created an exact-fit, high-quality performance replacement for all Single-VANOS M52 and S52-equipped BMWs. This cover features durable aluminum construction, which eliminates the warping issue found on OE plastic and magnesium valve covers. Unlike the OE magnesium cover upgrade, Bremmen's aluminum cover retains the forward oil fill location found, allowing you to retain your existing engine beauty cover.

Whether you're replacing a warping plastic cover or preemptively replacing this failure-prone component, Bremmen has you covered with a direct-fit aluminum valve cover upgrade.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold

We have seen so many M52/M54/S52 Vanos line failures at the track that we have to offer you a solution. The factory line is prone to failure due to the OEM hard-line - this rubber line alleviates the issues imposed by the factory design and enables you to worry less about your Vanos system. We trust ECS Tuning's Exact-Fit Stainless Steel lines for several different applications, and their M52/M54/S52 Vanos line is no exception. Bavarian Autosport's M52/M54/S52 Exact-Fit Rubber Vanos Line offers several benefits over OEM. Not is it they more durable and reliable OEM, but it is also easier to install, and significantly less expensive than the factory BMW Vanos line (11361705532) or other alternatives available on the market. If you're factory Vanos line hasn't failed yet, we still recommend replacing yours with Bavarian Autorsport's Exact Fit Rubber Vanos Line M52/M54/S52 to avoid eminent future failure.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies.

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.

This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.

If you need the hydraulic belt tensioner, click here.

This item is 70mm Diameter. Please check the diameter before ordering.

This tensioner pulley fits the following BMWs: 1991-1995 E34 525i (M50 engine) 1992-1999 E36 325i, 325is, 328i, 328is, 323is 1995-1999 E36 M3 (M3 3.0 & M3 3.2 liter) 1997-2003 E39 525i, 528i, 530i - Only for Hydraulic Tensioner 1999-2000 E46 323i, 323Ci, 328i, 328Ci - Only for Hydraulic Tensioner 2001-2005 E46 325i, 325Ci, 325xi, 330i, 330Ci, 330xi - Only for Hydraulic Tensioner 2001-2006 E46 M3 coupe & convertible - Only for Hydraulic Tensioner 2000-2006 X5 3.0 liter (E53 chassis) 2004 E60 525i, 530i (M54 engine) 1997-2002 Z3 & MZ3 2.5, 2.8, 3.0, M Roadster, M Coupe 2003-2009 Z4 M Coupe and Roadster
