Your photo shows a pretty thick layer of bearing material at the parting line, and the diagonal lube groove is still there. Don't trash that engine- - - -someone experienced at scrape-fitting bearings can fix it easily. You can mount a magnetic base dial indicator to the block and check the main bearing journal for runout if you're concerned about a "bent" crankshaft- - - -which is pretty unlikely. People who are accustomed to working with glass-smooth insert bearings just can't comprehend the process of actually making a bearing fit the shaft it's running on. I guess when old geezers like me finally take a dirt nap, that skill set will go away with us- - - -nobody is interested in learning how to do it.
