    What's the deal with my crankshaft?

    Ok, end up taking the crank to the machinist said those holes were strange but said wont be an issue. Crank getting a grind and balancing done. Just glad there's no need for a replacement.

    Looks like a Brinnel hardness test gone wrong, as Thom said, and someone didn't use sleeves over the rod bolts when installing the pistons. (Small chatter marks). The crank should be OK if it was in a running engine, it would have failed by now for sure. Just need to make sure there are no sharp edges around the dents, use a 5 or 6 mm drill bit BY HAND, and slower chamfer the 'holes' then linish the journals with some emery tape etc.
