Oil Filter Leaking at First Prime of Oil Pump

Marcohotrod said
the oil comes thru the block in to the area behind the plate - where the gasket is - thru the holes into the filter. more holes = more flow into filter = less load on gasket. how could anyone drill a few extra holes in a plate and increase backpressure?

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.
