My Truck in my signature is experiencing some strange issues. I have been experiencing rough idle, low power and oil consumption. Years ago I swapped out the OEM IP for a Moose pump and a fresh set of injectors. Last Septemeber I replaced the Moose with a Moose JR and fresh Conestoga injectors due to hot start issues. 2 months ago I sent the Moose JR in for warranty work after 6k miles and Mel rebuilt it due to a damaged head and rotor. After I recieved this current IP the Truck ran OK aside from some unusual oil consumption and an increased sensitivity to where I purchased my diesel and what fuel additives I was running. I use Stanadyne Lubrication Formula or Opti-Lube XPD. Historically this Truck has run very well and aside from some hot start issues that were resolved with IP's no other issues such as ticks, knocks or overheating. Last week while driving unloaded, it became difficult to maintain 70mph. The Truck was losing power and getting HOT. The temp gauge was nearly in the red and I could smell old oil cooking off of the engine. The EGT's were 1000-1200*F, the exhaust was billowing thick black smoke. The transmission was downshifting normally but the engine was being dragged down like I was riding the brakes hard. I quickly looked for a freeway exit and while keeping the throttle depressed as soon as I exited the engine died. I popped it in neutral and coasted to the side of the road. While waiting for my buddy to tow me home I attempted to crank the engine and it sounded slow and labored. Once I got home and the engine was cool I was able to start it and let it idle. As soon as I shifted it into D the load was too much and the engine died. The coolant level is normal, the oil is normal and there are no signs of oil or water mixing anywhere. I can't understand what would drag the engine down so severely and cause it to run so poorly. The fuel and air filters are fresh and clean. The timing is set to 8-9* BTDC.
