    3 trucks to make one!

    Hey all. I have what is a question of experience or possibly legality. I purchased a 4x4 powerstroke just for the engine this summer. It's wrecked but he's a good title. Now, I just purchased two other f250s. One is a 4x4 1990 NA IDI with welding body and a factory dually conversion. This...

    1990 f250 with 7.3 idi, 141k, mostly stock When going down long and straight descents, I have the throttle very lightly down, just enough to fully engage the transmission and the truck has a lot of mostly white smoke coming out of the exhaust. This will also happen when coasting in gear, but...

    Waste Transformer Oil

    Has anyone used the mineral oil from a transformer in an idi. How well does it need to be filtered or is it already relatively pure.

    Rotella 15w40 vs Rotella 15w40 Full Synthetic

    Simple questions: Which one is better for the 6.9 IDI ? Any advantage of using one over the other ? Anyone use the Rotella of either "blend" ? Reason for asking is that I'm due for an oil change and I can get a gallon of Rotella 15w40 for $12.50. The Synthetic is obviously a little more...

    Temp sender replacement

    So I installed a turbo (Hypermax) on my '93 7.3 IDI and that's working pretty well (need to adjust it a little because I'm only getting up to 7 psi of boost, but for now that's ok) but since I installed it I've always had the Engine Temp light turned on on my dash. I didn't think much about it...

    Differences between the 6.9 and the 7.3.

    I have an opportunity to buy a couple of 7.3 IDI engines. In a previous post I asked about pulling the heads off of my 6.9 in the truck. I bought an ARP headstud kit, a head gasket kit and an intake manifold gasket. I know that the head studs won’t interchange because of thread size. Might the...

    Pulling heads from a 1983 F250 6.9

    Well it seems as if I may have had a head gasket blow on my 83-6.9. Something poked a hole in my radiator as I was driving it and started to lose power and when I stopped it was blowing the coolant out of the hole in the radiator. I let it cool and refilled it and restated it but now I have a...

    WTS 1991 F-350 Crew Cab SRW 7.3 ZF-5 $3500 OBRO [SW Houston, TX]

    This turned out to be more of a project than I can deal with right now. The truck starts, runs, and drives, and is pretty solid, with very little rust, strong motor and good transmission. The original 4L10 rear failed, so I installed a 3.55 - original 4.10 is included if you want it but needs...

    1989 Diesel Ford F-350 4x4 crewcab longbed in San Diego

    Let's start with what's wrong with it; there is coolant in the oil. It started off pretty slightly, and so I rebuilt the heat exchanger. The problem got worse, so I thought maybe it was a head gasket. Now I've had a mechanic look at it, and he's measuring over 25 PSI in the coolant system...
