Blue Smoke from Exhaust When Accelerating

Posted on the 09 June 2021 by A2v

Car trouble symptoms

When the your car aceelerate, there is a blue smoke that comes out the exhaust.

Car problem diagnosis

Blue smoke during acceleration is an indication of a worn valve stem seals. Valve stem seal prevents oil from entering the combustion chamber, if the seal is worn or gone bad, the oil will get past the valve stem into the combustion chamber. In this case, the oil inside the combustion chamber will be burned and blue smoke will come out the exhaust.

Possible cause of blue smoke when accelerating

Bad valve stem seals


What to do?
Bring your car to a reputable auto repair shop and have the mechanic check the valve stem seal and replaced if necessary. You are lucky if your car is under warranty because you will be covered if not then you are facing a costly repair. Just replacing the valve stem seals usually corrects the problem, however, if the problem of blue smoke from the exhaust while accelerating still occurs then you’ll need a complete valve repair job and as I’ve said it will cost you a lot.
