Then, I doubt your Main Bearings gave out. If your #1 Main Bearing gave out it would have starved a lot more than just your #1 Rod Bearing. Oil stoppage at #1 would have dried out All the other Bearings in a daisy chain. Your #1 RB may have been too loose and you might have lost the oil film.
When you took out the spun #1 and replaced it with the original one, did the engine “knock” right away?
