my boss is an idiot

ok so my boss went an bought an 05 f550 dump truck. had to have it delivered because it didnt start (first mistake dont buy a truck with out starting it). i got it running but it blows white smoke for the first five minutes and then switches after warm to a dark grey to black smoke, very thick. when i goose the throttle the the turbo doesnt seem to want to spool. i pulled the intake apart to check the turbo to make sure it spins freely and it does. no codes are being thrown. the truck has a fresh oil change on it. any one have any ideas on where to go from here. im worrying that it is the egr or the head gasket and the computer is trying to compensate the loss of power by adding more fuel which causes the black smoke.

Howdy, and welcome to the ORG.

White smoke is the giveaway that the EGR cooler has most likely failed. I would not continue running the truck, to prevent you from hydrolocking it.

I would get it towed to a shop, and have them pressure test the coolant system, check ECT/EOT delta, check FICM voltage at cranking, and check the injectors and turbo for signs of sticking (easier on a diagnostic computer).

Sorry to hear ya'll bought someone else's problem 6.0L.
