Metal/Rubber Gasket
If your BMW is leaking oil there is a good chance it is due to a worn or faulty oil pan gasket. Any service that requires removal of the oil pan will also require a new oil pan gasket since it is one-time use only.

Engine Oil Pan Gasket
An engine oil pan gasket is a critical component that seals the connection between the bottom of the engine (block or bed plate) and the oil pan. Whenever the oil pan is removed, the engine oil pan gasket should be replaced with a new one.
Engine oil pan gaskets are made from different materials such as cork, rubber, silicone, or multi-layered steel, depending on the vehicle manufacturer’s specifications and the style and material of the oil pan. Rubber and silicone gaskets are particularly common because they are durable, flexible, and resistant to high heat and oil exposure.
Engine oil pan leaks can be messy and tend to get oil everywhere, so if your oil pan is leaking or if you are doing other engine work, it's important to make sure the gasket is in good condition and installed correctly.
Installation of a new oil pan gasket generally involves draining the engine oil, removing the oil pan, cleaning both the pan and engine block surfaces thoroughly to ensure a proper seal, and applying the gasket. It's essential to tighten the oil pan bolts to the manufacturer's specified torque in an even sequence to avoid warping the gasket or pan, which could lead to leaks or even crack the pan.
Engine Oil Pan Gasket Failure Symptoms
Mysterious Oil Leaks: If you have recently noticed a drip of oil on the ground, you should take some time and inspect the bottom of the engine, taking care to note the engine oil pan gasket. This is especially true if the oil pan has been recently removed or replaced.
Age: While not very common, an engine oil pan gasket can leak on its own just from age. If a vehicle is left to sit for a long time, it’s possible for the gasket to leak if the engine comes back into operation and starts experiencing heat cycles that may result in a seeping oil pan gasket.
Physical Damage: Simply removing an engine oil pan can usually cause enough physical damage to cause leaks if the gasket is not new. Whenever you remove the oil pan, be sure to replace the engine oil pan gasket.
Warping: If the engine oil pan gasket is not tightened down in the proper sequence, you risk bending or warping the oil pan. This is especially true with engines that use a stamped steel oil pan over a cast aluminium pan.
