Blown turbo or hung jake?

yes when they get worn they have a tendency to stay stuck in the advanced position.

 

it's been a while since i've seen one of those if i remember the weights have a (finger) that sits in a grove when they spin the spread out and advance the pump timing. some times they will (jump) out of grove keeping timing advanced or retarded depending on which way they are they do break or the springs break or fall off. if i remember didnt you have trouble getting the injector pump off? if you spun the nut thats on the front of the timing cone you might have it adjusted wrong and that could of messed the weights up.

 

Engine heads or Ecm

 

Ok when you hit a hill do you hear a whistle from your turbo???

If it happened you broke push rods because timing was not set up right it is very likely that some valves got bent and not sealing properly. Combustion pressure under load may squeze in that micro gap between a valve and a seat overcome a spring tension and open the valve. I am not saying that they bent really bad but just enough for combustion pressure to leak in and push that valve(s) down. Hope it is not your problem.
