What to look for when buying OBS 7.3

Okay guys I'm new to the forum so I may not be following rules. I apologize in advance. I'm looking into buying a 97 7.3 with 260k miles. It has ts 6 chip and banks power pack. Also has upgraded injectors and a built tranny. Interior is pretty clean being 20 years old. So basically is it worth buying being modded and would I be able to put say 150k more miles on it with me taking care of it. Also like the subject states what to look over prior to purchasing? Thanks.

Do the oil cap test to check for blowby. Search 7.3 oil cap test on youtube. Also check coolant condition, motor and trans oil. That built tranny better have an upgraded trans cooler because the stock one is smaller than the one on 4 banger civic.

ask when the last fuel pump was put in. check the valley for oil / fuel
leaks. ask when / if the fuel bowl has been rebuilt. check turbo for
shaft play. i'd check all of the i beam bushes as well.

If you are concerned about the condition of the motor have a compression test done. If those numbers are good and within acceptable limits then go from there. I would not buy any diesel without having one done. It is too much of a risk seeing how expensive these motors are to replace. It can make a cheap truck real expensive real quick. Maybe somebody else could comment further.
