Product Information

Proper maintenance of the drain plug, including regular inspection and replacement of the sealing gasket, helps prevent oil leaks and ensures efficient oil drainage during service intervals. If the drain plug is tightened outside of spec, it may break and require replacement. This Elring OEM drain plug is a reliable replacement part that will keep your BMW’s engine properly sealed and free from leaks.

Engine Oil Drain Plug
The engine oil drain plug is a small port located at the bottom of the oil pan. Its main function is to seal the oil pan and provide an access point for draining the engine oil during service. Typically made of steel or aluminum, and sometimes plastic, the plug works with a rubber or metal gasket to prevent leaks. It is removed during oil changes to allow old oil to drain, then reinstalled to reseal the system.

Engine Oil Drain Plug Failure Symptoms
Oil Leaks: A worn, cracked, or improperly tightened plug or gasket can cause oil leaks, leading to puddles under the vehicle or visible residue near the drain plug.
Stripped Threads: Repeated overtightening or improper installation can strip the threads on the plug or oil pan, preventing a proper seal and complicating future oil changes.
