94 7.3 IDI Turbo

I am going to look at a 94 f-350 with a 7.3 IDI turbo. It has 314,000 miles with a automatic trans. What are some common problem areas of big expense to look at. I am new to diesels but understand mechanics pretty good so i understand to feel for trans slip and stuff like that just want to know if there are engine issues i can look for. Thanks in advance for any help

IDI's are tanks! They are not fast, they are not as readily powerful, they are not quite but man-o-man once it's started you ARE getting from point A to B. This '94 you are looking at may or may not have a turbo. Banks and ATS make whole kits to up the power in these things. I have not owned one but I have two friends with IDIs and they love them.

Don't forget to look here to talk to other IDI owners. IDI Owners

The same as other diesel's the two big area's to watch for are excessive crankcase blow by and cylinder wall cavitation. I've owned several and built even more of the 6.9 and 7.3 IdI engines and believe me they can be made to be powerful and fast. The Idi engines are more prone to cylinder wall cavitation because their compression ratio is at least 3 points higher than a 7.3 powerstroke.

Turbo was a option in 93/94. The 94 Idi 7.3's with factory turbo where severely detuned so as not to compete so much with the powerstroke coming out in 94.5

Another good thing about those is even if the motors grenade, you can get another one cheap and all of the parts are cheap and easy to repair, wish I kept my old 6.9
