Without more pics, its hard to make the call...
The striping in the top bushing is from a lack of oil (metal transfer) . I'd like to see the crankshaft bearing and rod surfaces. This looks like the top of the engine was starved for oil ( 5 PSI ) . The oil in this engine goes from the oil pump to the filter to the top bushing, and then to the rods. I've seen the welch plug in the crank come loose and cause a similar failure.
If the oil pickup tube fell off it would do the same thing..
Without pics , its all speculation...
