Found under vavle cover
Pulled my valve covers to set the valves and found this laying next to a valve spring. Been about 2000 miles since I set the valves (solids) so it was time. Looks big enough to at least block an oil passage. Any ideas what it is and where it might have come from? It's not a ball shape, it' kind of tapered on each end. Hope the pic shows it well enough.
