Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.

BMW vehicles are prone to oil separators freezing in cold weather if driven before the engine is fully warmed up. This can lead to a howling noise followed by multiple oil leaks. The crankcase breather valve vents oil vapor from the engine block to the valve cover, but condensation can sometimes cause it to freeze, leading to a failure of the entire oil separator system, causing it to crack and break down. To prevent damage to your engine, it’s best to replace all components of the oil separator system at once. Replacing everything ensures reliable performance and durability. Remember to also order a valve cover gasket to make the replacement process easier.

Keeping the oil inside your engine is extremely important to performance. Between oil change intervals, your oil can dip to dangerous levels if there is a leak you may not be aware of. The valve cover is an extremely common place for this to happen. Years of exposure to extreme temperature change degrades the gaskets and causes failure. Replace yours to keep your engine oil in your vehicle.
