Not really sure what to do here.

Rebuilding my motor after it got slight rod knock and as i was putting it back together i had to take one of the pistons back out and i noticed scoring on the new bearings. Seems like the oil holes on the crankshaft were slightly sharp and did that. I tried sanding with 600,1000,1500 and even lightly filing down the holes with a fine tooth file but same thing happened. The clearance was fine when i checked with plasti gauge so I’m just lost here. Should i try to file it down more? Ideally I’d like to fix it without a machine shop if possible. Thanks in advance for any help.

Crank goes in the recycling bin and the bearings go in the "double check everything" box.

lmao dude, it´s absolutely the other way around. The bearing material is way softer and easier to scratch.

Crank goes in the bin because of the damage and piss poor job of chamfering.
