If you don’t have one there should be a warning light. If the engine is overheating currently, get it shut off as soon as safely possible.

These rings help the piston form a tight seal against the cylinder. When the cylinder and or rings get worn, oil from beneath the piston can come up. The oil gets mixed with the Gasoline and Air and gets burnt creating the Blue Smoke. Mechanics can check to see if the engine is worn. They remove the spark plug on each cylinder of the engine.

What to do when you get blue smoke from exhaust?

Look for a tube that connects to the Intake Manifold. Follow the tube back until you find your PCV Valve. Remove the PCV Valve from the tube and replace with new one. If Blue Smoke from Exhaust appears all the time your engine is running then your engine is probably worn if it is not the Valve Seals or the PCV Valve.

What causes white smoke to come out of exhaust?

Your engine is more than likely burning coolant. This can be the result of a blown head gasket, damaged cylinder head, or cracked engine block – none of these are easy on the wallet.
