The main CAUSE of white smoke is water or anti-freeze entering the cylinder, so the ENGINE STARTS to burn it with the fuel. That white smoke is nothing but steam. PREVENTION measures: There are special gaskets i.e. HEAD gaskets and primary gaskets that prevent the anti-freeze from entering into the cylinder area. This anti-freeze will produce a white steam which will accumulate at the tailpipe area.
