Maintaining optimal engine oil levels is crucial for peak performance in your BMW. Leaks can occur between oil change intervals, leading to dangerously low oil levels. The valve cover is a frequent culprit for such leaks due to gasket degradation from years of exposure to temperature fluctuations. Replace your valve cover to ensure the retention of engine oil within your vehicle.

Key benefits of replacing the valve cover include:

  • Preventing oil leaks that could lead to low oil levels.
  • Preserving engine performance and longevity.
  • Avoiding potential engine damage from insufficient oil.

Ensure your BMW's engine operates smoothly by replacing the valve cover to contain the engine oil effectively.

Includes the head gasket.

Sometimes you have to take the cylinder head off of your vehicle to diagnose problems, have it rebuilt, or replace a faulty head gasket. It tends to be a fairly labor intensive job, so anytime you can make it easier is definitely helpful.

When it comes time for reassembly, one of the biggest problems is finding quality gaskets and seals. Turner has your solution with this cylinder head gasket kit. With so many gaskets that are one use only to replace, getting them all done at the same time can be made harder by not having everything you need. With the proper, high quality gaskets, your reassembly will go much easier with no need for trip after trip to the local auto parts stores. Intake, exhaust, downpipe, valve cover, and in some applications valve seals will all help to get your engine into top condition.

When it's time to put everything back together, there are some things that should not be overlooked. Most cylinder head fasteners found on European automobiles are a one time use or stretch bolt. To be sure that everything is tightened down properly, it is important to replace them to get the proper torque reading and ensure the longevity of your repair.

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

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 this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. 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 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.
