Oil Filter Leaking at First Prime of Oil Pump

In my case I don't think it was a pressure issue I think I somehow distorted the plate when I drilled it. It was very crude I just used a hand drill on a wood bench, probably pushed too hard or something.

Could be, I usually use a drill press and step up size up as I go. I never drill straight to the size unless it's 1/8 or something.
