Usually white smoke is caused by water or anti freeze entering cylinder. in radiator or overflow the coolant will look like a chocolate milk shake. check on oil dipstick for traces of water or anti freeze. this would indicate a bad head gasket. look around head at gasket, and see if you can see any leaks. Most symptoms of a blown head gasket can be diagnosed through careful observation As the coolant heats up, and pressure rises, it will be forced into the cylinder during the intake stroke. This coolant will flash into steam during combustion and will be visible as a white cloud coming from the tailpipe. it may not even be a head gasket thats bad, cause usually if headgasket is bad, engine will overheat!! but if a bad gasket vehicle would miss and loose power. also check the pcv system ( positive crankcase valve ). hope this helps ! check system first !!
