Rub your finger over it, is it ruff???
Are you sure the bearing was not made like that???
Was the motor making any noise before it was torn down???
I have had bearings that were made like that with a little section
missing right around the oil hole. I have also seen some folks modify them
like that, to try to get a little more oil in there.
If it is smooth and is a tight fit when the cams is in there. I would leave it alone.
