7.3 non turbo oil going to radiator?

My boss bought a 90's model ford dump with a navistar non turbo 7.3 the truck sounded good when we got it off the low shifted good yada yada but had very little oil in it. . . .we filled it up and the mechanic took the radiator cap off to check it while it was running and all the oil went to the radiator I'm talking the stick had nothin on it . . . . The truck is in awesome shape and he offered it to me super cheap and now that I have made it home and don't have all the info I know I need lol I'm thinking about maybe trying to get it. Any chance it could be the oil cooler? Or do you think the block is cracked? No real experience with that kind of stuff. Anyone know where a motor is cheap cheap cheap?

We had a 6.9 back in the 80's that got a clogged air filter and sucked oil instead of air and cracked the block, oil ran out the over-flow. It still ran perfect with a cracked block... crazy. There was a 6.9 in the Phoenix Craigslist a week ago in supposedly excellent condition for $500, the # was 602-541-3889, suppose to be complete and could be started for inspection. I would bet your truck has a cracked block. Good luck!
