Keeping the oil at the right level should be a top concern for all BMW owners. And it is the oil pan that plays a key role in keeping the oil where it belongs. This pan is sealed by an oil pan gasket. The housed oil in the pan will leak, if the gasket gets damaged. A failing oil pan gasket can give rise to engine overheating, smoking issues, and other unwanted hassles. Being knowledgeable about recognizing the failure will help you to spot the right time for oil pan gasket replacement in your BMW.
