For several decades, the BMW brand has represented unrivaled performance and excellence. Whenever someone sees the blue and white geometric image resembling an airplane, German engineering, and European luxury come to mind. Even though BMWs are full of allure and premium materials, they are not perfect. And like every other vehicle, BMWs are prone to mechanical issues, including oil leaks. Let’s explore common causes of BMW oil leaks.
A Compromised Drain Plug Is a Common BMW Oil Leak Cause
Worn-out or broken drain plugs are among the top causes of BMW oil leaks. The drain plug underneath your BMW is where the engine oil is drained during an oil change. If you have an oil leak originating from the drain plug, it may be caused by an inexperienced German mechanic performing the oil change process.
On the other hand, most BMW drain plugs will naturally experience wear and tear. It can become corroded, and the seal no longer covers the hole. Fortunately, replacing a BMW oil drain plug is relatively straightforward.
Valve Gasket Cover Problems Can Cause BMW Oil Leaks
Your valve gasket cover is a seal that connects the engine and valve cover. The valve gasket cover is integral in keeping oil in the spaces it needs to be. During operation, engine oil circulates throughout your engine. However, if there is a problem with your valve gasket cover, the oil will spell out all over the engine. It often results in a puddle on the ground. A valve cover leak can resemble a drain plug oil leak, so it’s vital to have an experienced European vehicle mechanic inspect and diagnose the underlying cause.
Infrequent Oil Changes Can Cause BMW Oil Leaks
BMW and every other manufacturer suggest you have an oil change at specific intervals. It’s critical to stick to this interval. Failure to do so can allow a minor maintenance expense to snowball into more expensive engine repair. For instance, old, dirty oil will break down and corrode the parts it’s supposed to protect.
Old motor oil is full of small particles. And the older the motor oil is, the more difficult it will be for your BMW to remove the impurities. As this old, particle-filled motor oil moves throughout your engine, components, and parts will start to wear down because of the sludge and contamination, which can lead to BMW oil leaks. This underscores the importance of having regular oil changes as suggested by the manufacturer.
Timing Gasket Cover Leaks
Your timing gasket cover is a seal that protects the connection between your timing cover and the engine block. The rubber gaskets can harden, shrink, and allow oil to seep out. If your timing gasket cover is the cause of your BMW oil leak, you may also have a coolant leak.
