if it is white smoke engine need to rebuilt.
Sorry to tell you but you have a blown head gasket, cracked head, or both. The white smoke is coolant entering the combustion chamber. STOP driving this vehicle or you will destroy the engine. You must have this repaired and it is not cheap.
grey exhaust smoke is caused by your engine burning oil during the combustion process. this could be caused by a piston ring that doesnt properly seal, or another leak in your engine.
If the smoke is black it could be caused by a faulty fuel pressure regulator which could be causing the engine to get too much fuel.
White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.
