Smoke Colors From Exhaust
There are several different types of smoke that can be emitted by a vehicle, each of which can indicate a different problem. White smoke is typically caused by a coolant leak, while blue smoke is often the result of oil leaking into the combustion chamber. Black smoke is typically an indication of a fuel mixture that is too rich, meaning there is more fuel than oxygen in the mixture.
Different types of smoke and their possible causes:
|Color of Smoke||Possible Cause|
|Blue||Oil leak into the combustion chamber|
|Black||Fuel mixture that is too rich (too much fuel)|
