Bearings feel good by hand. I grabbed the piston and held the rod with the other hand, applied push pull motion and also tried side pressure. Didn't feel any slop or pop. I think the bearings are still solid. That was my initial thought too. Figured the crank main bearings had to be loose allowing out of balance rotation resulting in striking the wall. Doesn't feel loose though.
tbird, have you been in your motor to see if those are common? Like a machining mark of sorts. It seems real odd to me. I'm really thinking thats from rubbing. The marks are not uniform and they don't go all the way along the case there.
