Howdy and welcome. I'm out in NM, but really enjoyed my adventures in LA. ( I trust you'll get that)
Has the truck been maintained? If so, I wouldn't be afraid of it. I haven't seen an IDI
have that particular problem, but I have seen cracked cylinder walls on those blocks. The one I have records on did it around 200k, some did it new, some never did. I think the cavitation thing was more of a Powerstroke thing. But, anything is possible, and that's just my experience.
Honest opinion, I'd jump on a low mileage 7.3 IDI
, especially if it's turboed. Provided the truck is not a pile of rust draped over two frame rails.
Here's a picture of cavitation on a Cummins cylinder liner, an IDI
is not a linered engine, but it's easier to photograph since it's out. To prevent this, if you get the truck, change the coolant, proper mix of green low silicate and distilled water, and use an additive, I prefer NAPACOOL. ( Available at Napa)
