Is it white, blue, or black, if it is steam it is normal. white smoke is cracked/ warped cylinder head, blown head gasket, cracked engine block. Blue smoke is spark plug O-Rings, valve seals, piston rings. Black smoke is excess fuel in system from faulty sensors, faulty fuel pressure regulators, faulty injectors, faulty fuel pump, or you need a new fuel system.
