I have noticed what appears to be a whitish color of smoke coming from my exhaust only when I accelerated to get on highway. I recently broke my oil pan and didnt notice it doing this before. Nobody thinks its the head gasket becuase no loss of coolant, no overheating. Car runs the same as before all fluids are good again not overheating when I drove it. It has done this 3 times in the last 2 weeks from replacing the oil pan. Any suggestions on what could be causing the smoke(besides a head gasket)? Im afraid to drive it until I can pinpoint where its coming from so I dont damage the engine.
