I suggest finding a method to observe the crankshaft end play. Judging from the appearance of the pilot bearing there has been continuous, substantial, forward pressure applied to the thrust surfaces. I would not worry about .010 but the rod side clearance and piston pin clearances can be exceeded leading to potentially serious engine damage when excess end play exists.
