Hey Nate, you still looking for another engine to tear down and learn on? This thread and a couple others have got me thinking, and since it's so hard to explain via internet or text message, maybe we should find a donor. Even a windowed block will work at this point.
I'm willing to bet a fair amount of money on pop testing those injectors and finding 4 or more that are ******* like crazy. Would also explain the horrendous fuel economy that you and I had experienced. Wish I had the time and money, and didn't have to deal with the divorce, to keep and work on that truck.
