Even though engine oil leaks are very prevalent in some BMW models, they shouldn’t be disregarded. The valve cover gasket, timing cover gasket, front crankshaft seal, rear crankshaft seal, or oil pan gasket are the seals or gaskets that leak engine oil the most frequently. However, simple mistakes like not tightening the oil cap enough or failing to properly plug the oil pan gasket after an oil change can also result in oil leaks in your BMW. Oil leaks in your BMW are typically caused by one of these valves or seals wearing out. The latter is a frequent reason for oil leaks in the lower engine area.
