it could be your head gasket has gone. normaly it is blue smoke if it is oil.white smoke is normaly steam from a head gasket as water passes though the chambers.and exits through the exhaust if it has blown through a water way check oil to see if you have any trace of white gunge as this may give you a clue. or see if you have any bubbling coming through your header tank as this is a clue that it is blowing across the water ways. hope this is of some use to you

White smoke from a diesel can be a couple of things.

At start up it is usually cold cylinders not allowing the fuel to burn correctly (you often see this if a heater plug has gone)

If this is during normal running when the engine is up to temperature then your fuel pump timing is probably retarded. Did you have a cam belt change earlier this year?
