Not much, really. I did some measurements on the crank journals, they are all uniform and don't show any wear, so I dropped the crankshaft off at a machine shop for polishing. I ordered new bearings, once they arrive I'll assemble the bearing carrier, so there's that. Regarding the wear on the main bearings, I contacted the original owner to get to know more details about the circumstances of the failure. He says the engine was running for about half a minute after the bang and it was running pretty rough. So, it's surprising that the engine did not just stall, with only 3 functional cylinders. It's also interesting to consider that it was running without oil returning from the head to the sump, potentially resulting oil starvation at the main bearings at idle..
