93 idi smokes horrible

[buddaniels]

Have a 7.3 that blows white smoke .alot. no air bubbles in the return lines. And has consistently shown 440# of compression on all 8. Any ideas?

smoke smell like unburnt diesel or coolant? I checked my over flow for the tube pushing bubbles in it which told me my head gasket was going out (even more) before I replaced them. hope this helps sure someone else will come along and help as well.

Does the smoke clear up when engine is up to temp? Might just have a leaky injector or more, White smoke is unburn't fuel on cold engine startup.
