usually a sign of timing, so maybe a leaky line or injector?

the truck runs good. its still got a miss after the new injectors. im going to take the pump and get it rebuit here pretty soon. i want to go ahead and freshen up the motor though because its got 330,000 miles on it. it used to be an old hot shot truck and ive been hot roddin it since it was retired so it wouldnt hurt. theres no leaks in the fuel system.

Coolant level going down at all? White can be coolant burning as well. What conditions does it smoke white? Hot, cold, lots of boost, anything specific?

Question

It smokes white most of the time its running. It ain't duppin smoke but its visible. And then occasionally it wont smoke white at all. And yes the coolant level drops after some time

How fast does the coolant level drop? Any external leaks? It would be a good idea to do a coolant system pressure test. Hate to say it, but it could be a head gasket. Hope not though.
