The commonest cause of white smoke is likely injector pump timing.

So, any decrease in the pressure or delay in the fuel delivery to the combustion chamber will result in incomplete combustion, leading to white smoke. An engine burning coolant can be easily determined. First question, do you have to regularly add coolant?
