I had a leaking injector but it was black smoke from running rich...I wonder if white smoke could mean this to?? I have white smoke come out of my tailpipe only when the car sits for a bit...not while driving or stopped at a stop light. It s a good deal of smoke also. Coolant is full, no residue on oil cap...I have a OCC and a robbeck upgraded valve. I do a lot of logging and the car is running perfect. I wonder if this problem above and mine are from a leaking valve cover leaking a small amount of oil into the spark plugs and when the car sits overnight the oil is a bit more...we start the car up and burn the oil. The only thing is why is the smoke white...it would have a bluish tint if it where burning oil, and a sweet smell if burning coolant. I am not fully kitty-less....have kitty-less Dps. I have a vid of this also.
