2012 Peace, mercy, and blessings of God be upon you. To whom it may concern about white smoke when the car is stopped and it stops after driving a little, I have brought you the solution. Your problem is with the valve seals being widened or dried out, and the only solution is to replace them. Of course, we can remove these seals without removing the engine or the heads. We replace all 16 seals, and God willing, the problem of intermittent smoke will end.
