Guess that noise

OK, not the end of the world. The good part the rod bearings are soft and took the hit. The crankshaft looks worse than it really is because of the small amount of bearing material that transferred to it. The bearing material on the crankshaft can be polished off and new rod and main bearings installed, also needed new oil pump too. A creative mind can actually polish that crank in the block without pulling heads or pistons, takes some doing but can be done. Takes some finger work, and some high density foam plugs to keep debris out of the oil galleries.

First order of business you want to see how far the damage has gone. Bottom half of the Main Bearings are the first to start to go in a low oil pressure oil situation.

Want to look into the cam bearing edges with a light to see if they ran dry peeling the edge of the bearing out like a banana peel, most suspect would be the front cam bearing as it is farthest away from the oil pump.

Check other rod bearings to see if it is an isolated rod bearing problem.

Can pull the cover on the oil pump to see if there is scoring in there from low oil supply situation.

But yes, want to determine why it failed then move on to a solution.

Good Luck
