My question is, what kind of oil was he using that it hadn't completely seized? There couldn't have been much left in the oil pan after all that damage!
I think we can rule out Quaker State non detergent, that stuff left carbon behind by the ton and the engine was comparatively clean. Of course most of that carbon was in the top end. Wasn't Quaker State Supreme, that stuff would have probably caught on fire. It wasn't a synthetic oil, that didn't exist for sale to the general public. If they did I never heard of it. Castrol still sold bean oil, no mistaking that smell, wasn't bean oil.
The engine didn't seem particularly hot.
s10 pickup ran out of oil and put a dollar size hole in the engine block, it made it all the way up the grape vine and was still running when I pulled into a gas station. It kept running until I turned it off but then it locked up and wouldn't turn over again.
I expected this engine to be locked up when he came back. Started fine and looked like some sort of mechanical display to show how and engine works. One thing I just remembered, this engine had dip cup rods. No pressurized crankshaft oiling system but each rod scoops up it's oil directly from the sump. I guess this explains why an oiling system didn't clog and freeze the engine. Memory fails on those engines. Did the dipped oil have a path up the rod to oil the mains?
Here is a story for you. An older man working for me told this story and swore it was true. He did mechanic work, maybe had a shop. He also had an epileptic daughter.
He had just bolted an entire fresh 327 engine from the parts house in his '55 Chevy. Just finished putting water in it when his wife came outside screaming. Got his daughter into the car and twenty miles to the hospital pretty much wide open! When he got to the hospital they knew his daughter and his wife had called so it didn't take but five or ten minutes to check her into this small town hospital. When he got back to his car it was sitting there with the engine turning backwards like a hot engine will do sometimes. He didn't have anything to lose so he kicked in the starter and managed to get the engine running forwards and drove it back home!
He slept a few hours and after a cup of coffee he went out to the car. Now the engine was locked solid! Fortunately there was a guarantee so he got another one free.
Yeats later Tom and the parts house owner were in the bar together. The parts house owner knew there wasn't something quite jake about that engine return so he asked Tom about it. Tom said "You know my daughter is epileptic. She had a fit and I had to rush her to the hospital. I had just put water in the engine but I didn't have time to put oil in it. Twenty miles to the hospital, twenty miles back, no oil!"
The parts house owner cursed him out but was only half sincere. He knew he might have tried the same thing in that kind of emergency.
