Default Oiling problem

I'm having a weird problem with my 2010 camaro...

All started with a zero oil pressure on a cold start after a week sitting.

Problem got solved after changing the filter so we thought the filter went bad.

Used it for the day without a problem, after sitting overnight zero pressure again.. popped out the filter, cranked to check pressure was fine, reattach filter, pressure ok... let it sit overnight again.. same crap...

8qts of oil on the pan...

Any theories?

For the life of Me I can't understand why they would make oil filters without the anti drain back valve ,,,,,,but they do ,,,,,,,,I was buying a filter for My 5.3L at Wal-Mart and in the book they listed filters with and without that valve ,,,,,,maybe it's 1 without that You have ?
