Hello all, I just picked up a 2006 king ranch CC dually. Both coolers and head gaskets have been replaced. I noticed today when pulling away from stop lights she puffs a little bluish-white smoke. I can't see any smoke at startup or when romping on the throttle. The truck was basically parked after the engine work, and hasn't been driven much in the last few months at the dealership. Any thoughts?
