What to Do If a Car Burns Engine Oil?
2 Answers
Solution for a car burning engine oil: It is necessary to remove the engine cylinder head and replace the valve stem seals. The main functions of engine oil are: 1. Lubrication: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Cleaning: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and flush away dirt generated on the working surfaces of parts through the flow of the lubricating oil. 3. Sealing and leak prevention: Engine oil can form a sealing ring between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering.
I've been driving for over 20 years and often encounter engine oil burning issues. Oil burning means blue smoke from the exhaust pipe or rapid oil consumption, which is usually caused by worn piston rings or aging seals in the engine. If you notice this, don't rush to repair it immediately. First, check the oil level yourself to see if it's significantly low. If it is, you can try adding some new oil. You can also buy repair additives to add to the oil, which might temporarily fix the leak. However, if this problem persists long-term, you'll need to consider replacing the oil seals or piston rings. This requires going to a repair shop, and it's both troublesome and expensive. Remember to change the oil regularly during maintenance, use higher-quality oil, and avoid constantly driving at high speeds, as excessive engine load can lead to oil burning. Keep the engine temperature under control and prevent the car from overheating. The longer this issue drags on, the more damage it causes to the car, so it's best to have a professional diagnose it early.
