    Have you ever had the timing calibrated in the ecm. ?

    When did this problem start. ? Was it after you had work done on it ?

    Sounds like the injection timing is super retarded when cold. No codes at all?

    I would try a test ECM if you can get your hands on one.

    Does it have fuel recirculation plumbing on it?

    white smoke is raw unburnt fuel if it smells like diesel, if it smells sweet then its coolant.

    If you are still near the cat shop that did head gasket take it back to them to get overhead run, after they have adj. valves if it does not run better they may have let it out their door with a tight valve and its burned the valve
