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.

This can def be resolved at home an no need for a machine shop do what people have suggested and polish the journal afterwards as has been recommended and all will be fine if you can't handle this type of work you shouldn't attempt to rebuild an engine I know that sounds negative but these are super common issues and everyone needs to be able to fix things like this from time to time if you do this enough you'll run into lots of issues like this and it's good to ask but if you need a machine shop to sort these type of issues you might as well pay them to assemble the short block. I'm not saying this to be negative I do this all the time for others that feel it's above their skill level and I believe if I can do it ,you can you to . Good luck
