Bob, this just looks like thrust wear to me. If you trust your gage and the pressure was indeed coming in and out, you ve got a problem somewhere that you have yet to discover. You said that you removed the oil pump. Have you inspected it and the gasket to make sure it couldn t be the problem? It just sounds to me that something got loose enough to impede and at the same time that loosening compromised the high pressure side. Did you take a good look at what might be laying in the oil pan?
A knock without a miss that develops instantly is almost always a slipped or spun rod bearing which comes with and sometimes caused by a loss of oil pressure. You say you don t have this and I can t think of any other possible immediate knock except some it coming loose in or around that oil pump. M

Good luck with it,

Joel there was nothing out of ordinary in oil pan. I had the original oil pump parts replaced when I did the rebuild just a few years ago but the cost of a kit it nearly the cost of a new pump so I'm going the new pump route. I'm also getting a new oil pressure gauge to insure myself that my original gauge still works. There were no spun bearings and all bearings were wet with oil. Hopefully this will solve my problem. Thanks for your help.
