Sounds like this failure for all opinions is due to a stuck injector (injector hasn't been formally checked).

As far as wear on rod bearings....they will show some wear due to label of oil pressure in start up, but the oil is designed to keep the bearings and the crank from coming into contact....hence the reason tight clearances being bad.

These bearings were way worse than a similar mileage S54 I changed the rod bearings on. This will continue to be an issue in the future on these motors IMO.
