BMW E39 528i Oil Separator Kits
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.
From the basic repair kit all the way up to a full oil separator overhaul - let ECS be your source for high quality replacement parts
