turns out it was number one rod journal spun. As I think back, I believe I put a higher viscosity oil in it thinking it would give a little extra protection. Now, I'm thinking that that thicker oil took longer to drain back down and I possibly cavitated the pump..That's my best WAG. The main journals look unhurt.
