Thanks to all for your comments. Based on your comments I had a closer look at the hole in the head where the pushrod exits. There is visible wear on the side of the hole. Not sure what would cause this but definitely the cause ( or effect ) of the failure. The edge of the valve now has a burr which I think I can burnish with a small stone. So … what now? Guide plate ? like they use for roller valve train or someone said that there is a rocker with a centering feature (lip) to prevent side to side movement . Pushrod does not appear to be bent (part #MPR-34-B) Thanks again all for your help
