Buy one to fix the issue and buy a second so you're not stranded in the future!

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. As long as you have everything off, you can rest assured that new parts will last and be reliable. Don't forget to order a valve cover gasket, throttle body gasket, and a new intake boot to make your separator change easier and more comprehensive.

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!

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem.

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

Oil leak on the E46 M3? The constant pressure valve, or oil pressure relief valve, is the most likely reason. This screw valve, located on the rear of the engine block behind the #2 header, has an o-ring that becomes flat over time, allowing oil to leak around it and down the back of your engine, transmission, undertray, and eventually to your driveway. If you see an oil leak around your transmission and think it's the rear main seal or from the oil pan, try replacing this first. Replacement is the only remedy as the o-ring is not available separately from BMW. This is an Original BMW part. One required.

Applications:
1993-1999 Euro E36 M3 (S50 Euro, S52 Euro engine)
2001-2002 MZ3 M Roadster, M Coupe (S54 engine)
2001-2006 E46 M3, E46 M3 CSL
2006-newer E85 Z4 M Roadster, E86 Z4 M Coupe
