Oiling hole or dowel pin hole?

What was going on with the #3 P/C?

Seems odd that an engine would last 25k and then suddenly have a 
problem with oiling at one bearing. I wonder if the end play was too 
tight?

If you can get that bearing off without further damage to the crank, 
you may be able to just polish it, but if it's blued from overheating 
it will have lost any surface hardening that it once had.

Even if you have to replace the crank, that's not so bad if nothing 
else got damaged. Still, the case will have to be align bored.
