So this is a picture of a rod bearing from the engine I had the antifreeze issue with.
All six bearings have the same mark in the same place. What caused it? It is deep and can easily be felt. The crank looks and feels fine.

Antifreeze has/is glycol. Glycol is in the glucose (sugar) family. Antifreeze in the oil reduces the ability of oil to lubricate the crankshaft.
At a very minimum, you have to first eliminate the coolant in the oil. I would change the rod and main bearings. The crankshaft should be measured (miked) to see how out of round it is.
