Thanks for all the replies in response to my last post about white smoke, since my last post I have redone the head gasket and had the head pressure tested and skimmed. New water pump and thermostat fitted. Full head set fitted and is still the same. The temp gauge and heaters are normal and the fan cuts in as it should, but by obd2 computer the temp gets to 100 0c and starts to bellow white smoke out of the exhaust. Really am stuck with this now, any help would be much appreciated.
