Thinking about buying an OBS what to look for

[Josh99]

I'm looking at a 97 automatic single cab with 113k on it. I swore to myself I'd never buy an automatic diesel but this one is a pretty good deal. Coming from a super duty I know the 7.3 but whats different between the trucks? Is there anything I should look at on it?

They are not intercooled.

also, check it now, when the weather is cooler, and make sure you call the owner and tell him to not plug it in or run it for at least 12 hours. it must be stone cold dead... and see how she starts up, coldstart/no starts are common on the obs. i learned the hard way by buying a truk that had been plugged in. when i went to see it, the next morning it wouldnt start. it cost me 350 dollars in replacing stupid crap to fix it.

Same basic motor and stuff to look out for as your truck. No IC as mentioned and 2 UVCH's per side. OBS trucks tend to burn UVCH connections more for some reason so check them over.
Oh yeah, don't forget about the mechanical fuel pump in the valley. When it goes bad there is a weep hole on the bottom that will fill the valley with diesel.
