I found a motor for sale for $1000. All I know is the guy said it was in some kind fleet truck and was pulled at 90k miles. It was in an 04 and he said it ran fine and is doesn't come with a turbo or injector wiring or a few other things I'll have to find the details on. My truck is an 05 and was wondering if there is big differences between 04 and 05 motors. I was wondering if this is a good deal. I would just like to have some spare parts considering my powerstroke isn't always the most reliable. Any thoughts will be appreciated.
I don't have a lot of specific 6.0 knowledge, but I can share some general concerns I would have: I would be wary of a "fleet truck" engine, regardless of the mileage, unless I could see it run--some of those trucks see the hardest miles (idling extensively, long maintenance intervals, etc.). The way I see it, the most expensive parts that we usually require are the injectors, the turbo, the HPOP, the Oil and EGR cooler, and the fuel pump (I might have missed a couple things like the FICM, etc.). Of those, you're already out the turbo, and who knows what condition the other parts are in. My .02? Use the money towards studs and EGR delete, and if you already have those done, then use it towards maintenance.
Edit: Another thought: If, however, you know for a fact that it ran great, it might be good as a "spare" in case yours ever takes a dump (drop one in while you redo the other).
