How to Solve Severe Oil Burning in BMW 525?

[LaKate]

Place a white cloth under the engine, then start the engine, and check for oil leakage based on the oil stains on the cloth. Confirm whether carbon buildup is causing the piston rings to stick. Damaged valve stem seals are a common cause of oil burning in BMWs, and they can be replaced without removing the cylinder head. If the pistons are severely worn and the clearance is too large, an engine overhaul is required, which will significantly reduce the car's value.
