If it's the only bearing to fail I have no idea why. I'm guessing an obstructed oil passage? Or maybe it spun them starved for oil. But still, why? The corresponding rod journals aren't bad enough to be no oil...gotta get that bedplate off...
Rod bearings bottom to top is back to front. Bearing tops on right. The fronts are the most marred probably because of what the mains threw off...
Finally, I haven't measured anything yet, and copper isn't showing on the rod bearings, and this engine had a subtle knock when warm only...could it have been the crank bouncing around? Or was one of these rod bearings shot enough to knock? Not sure.

There is wear on them , that's for sure . But I saw worse here on BP .
From what I know I saw rarely fail the mains (2-3 times) and only by the stress (extra torque) from a supercharger .
I really hope you can figure out from where the copper comes .. |
I found a nice chuck of aluminum wedged between the crank counterweight and bedplate too. I bet the bearing spun and the bearing tab gouged the block. The bed plate has steel inserts so it's gotta be the block...I'm starting to doubt it's salvageable but will try.
