What causes white smoke when you accelerate a little hard on a 1993 Toyota Corona AT when you bought it in November of 2006 and there is no white smoke while idling?

Answer 1

Hello, This could be cause by a couple of things, it could be the piston rings are getting tired (Whats is the mileage on the vehicle?) or the valve seals are getting also old letting oil pass trough it and burning when getting in the combustion chamber. White smoke is caused by oil entering the combustion chamber (Burning oil creates white smoke when burnt.)
