Any busnuts near Santa Rosa New Mexico?

Hey guys, I have a buddy with a 2004  28 foot international box truck with what I'm guessing is a 466 that is  underpowered and pouring out black smoke. He took it into a shop this morning and had all the fluids checked, oil changed etc. new air filter, 60 lbs of oil pressure, no coolant in the oil, brakes are free, temp is good. I'm guessing either bad injectors or a bad injector pump. Another possibility is an accordion hose that connects to the egr seems to have a a small tear in it. It's got 248,000 miles on it and it looks really good for its age. Bring on the advice boys
