you most likely have bad piston rings or in a overhead cam you might need to rebuild the topend
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.
Black smoke coming out of the exhaust of a car is usually due to oil being burned in the engine's cylinders. This can be caused by a worn piston ring or rings.
white smoke is coming from my exhaust why?
the smoke that comes out of a exhaust pipe is supposed to be white
NO
It depends on what color the smoke is. If it is white smoke that usually mean coolant is in the oil and that can be a result of a blown head gasket. If it is a greyish bluish color then it is oil burning. if it is black then you are burning gas.
The answer depends in part on the color of the smoke.
It is buring oil this is a wrong answer whe engine burn oil to the exhaust smoke is a heavy white smoke no black
If is a whitesh smoke then the head gasket has likely blown. The coolant is what gives it that color. If it is a bluesh/blackesh color then a piston or valve has been damaged. This is the common causes.
Burning oil
yes.
Car maintenance is very important for a smooth ride. When there is white smoke coming out of the exhaust, it is usually an indication of water in the engine.
