How to Solve the Oil Burning Issue in a 2011 BMW 320i?
1 Answers
Cold engine oil burning but normal after warming up is caused by aging valve stem seals. Remove the engine cylinder head and replace the valve stem seals. If blue smoke is still emitted from the exhaust pipe after the car reaches normal operating temperature, it indicates poor sealing of the piston rings. Replace the piston rings. Buffering the pressure rise at the engine cylinder ports; flushing away dirt generated on the working surfaces of parts - these measures can help solve the oil burning problem.
