The timing cover is designed to protect the timing belt, timing chain or cam belt in your BMW car from road debris, grime and gravel. Without the protection of the timing cover, the belt will skip, slip off the timing gear or even break. Usually, the timing cover is made of plastic, metal or both. However, no matter how tough the material is, there is one day for your timing cover to fail. Here are some signs showing your timing cover may go wrong: if the engine oil or engine coolant leaks in your car; if there is a rasping or grating sound coming from the front of the engine; if there are some missed timing marks, which means misalignments. Check your timing cover, including gasket, regularly. Once you decide to change your timing cover, we are glad to be your first choice for your BMW genuine OEM timing cover, and all prices we offer you are the lowest and cheapest.
