How To Get Rid Of Blue Smoke From Exhaust?
What causes blue smoke from exhaust?
The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise.
Is blue smoke from exhaust bad?
If the positive crankcase ventilation valve gets stuck, the oil, air, and gas will continue to mix inside the engine. This is very bad and will cause blue smoke to come out of the exhaust. Worn Engine: Another common cause of blue smoke is a worn engine. Every engine has pistons that move up and down the cylinder.
How do I stop my exhaust from smoking?
