Sounds to me like gas and or oil smoke. When checking the oil is there a noticable amount gone? If in your area there is a emissions requirement that can tell you a lot about how much actual gas is NOT being burned inside the engine. I would look at major tune up, oil change, and o/2 sensor. Good Luck.Answer # 2Greyish black smoke is a sign of worn out piston rings
White smoke is a sign of leaky/busted head gasket
Blueish grey smoke is a sign of bad PVC valve, O2 sensor or both
Sounds like engine coolant is getting into an engine cylinder
what is the worst for your health breathing in tobacco smoke or exhaust fumes
is there blue smoke coming out of your exhaust? if there is then there is probably oil leaking into the cylinders.
emissions and exhaust
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
how can i get black exhaust smoke stuck on my dual exhaust
smoke poured out of the exhaust of the car.
It is buring oil this is a wrong answer whe engine burn oil to the exhaust smoke is a heavy white smoke no black
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
The answer depends in part on the color of the smoke.
What colour smoke?
Depends on the color of the smoke. Blue smoke-oil. Black smoke-unburnt fuel.
