Would the guy care if you took it somewhere and got a buzz test and cylinder contribution test?
Appears to make plenty of power. And the guy is a "mechanic" at an oil change shop and says he doesn't know much about these diesels and just selling them for a friend (already sold 3 others). I don't know if it is the injectors or not but I told him it needed all 8 new injectors to talk him down on the price. He didn't seem to know much about diesels, but I told him they cost $285 a piece and the IP would have to be replaced too ($700). Of course really I have no idea whats going on with it as I'm kinda new to diesels too. I have some experience with the 7.3 though and they are very tough long lasting engines if maintained.
