If it's run 2 days with good oil pressure and no ugly noises, I'd quit worrying much, but I'd watch it careful.
Back in 1991, I was in the sawmill business, just barely. I'd just had a major customer go under, almost taking me with him.
One Sunday my father wanted to use my single axle dump truck to haul sawdust from my mill to his garden. I told him to take plenty of engine oil, because my loader was losing it quickly (turned out to be through the hyd pump). The loader had a Ford 175 ci Diesel in it that I had completely rebuilt a year before.
Monday morning, he told me he was sorry he had screwed up. He had driven to the mill (10 miles of dirt logging road) and forgotten the oil, so he didn't even check it, he just loaded. Every trip, he forgot the oil until he got to the mill. Halfway through the 7th load, the oil light came on. He figured he'd finish loading and then shut it down! It locked up in a couple more buckets.
I put 5.5 quarts in a 6 quart pan, then had to hook 2 trucks to it to get it to turn fast enough to crank!
When it started, it had a terrible knock. I left it idling at about 550 rpm. He asked what I was doing, I said, "I'm going to sit here and watch a rod come through the block, then I'm going home and change clothes and look for a job!"
After about 10 minutes, it seemed like the knock was lighter, after 20 minutes, it definitely was. After an hour, you couldn't even hear it. It ran another 3000 hrs with good oil pressure, and is running still, but I don't know how well.
So, you may have my father's luck, and have dodged a bullet!
