This Rein Automotive repair kit allows you to service the internal components of the crankcase breather valve independently. Instead of replacing the entire, costly valve cover or manifold assembly, this kit provides the exact wear items required to rebuild the factory housing back to original operating specifications. All components are manufactured to strict OE tolerances. The diaphragm is molded from premium, oil-resistant elastomers engineered to withstand prolonged exposure to aggressive synthetic lubricants, fuel vapors, and extreme under-hood heat cycles without losing its elasticity or sealing profile.

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.
