If it is the turbo seal I would imagine it only smokes when cold due to tolerance changes maybe? After it warms up, the expansion helps the seal do its job. Early signs of the seal going out. Someone correct me if I'm wrong lol. Also if you already have the head off isn't there a way to put something like oil on top of the valves? If I remember correctly if the seals around the valves are bad than oil should leak past in a certain amount of time. Something along those lines lol
