I GOT IT! Finally got the old one out and the new one is in there. I think I found my oil pressure culprit, when I removed the screen there was an entire pan gasket end piece stuck inside all dried and cracked up. This could explain the off again on again oil pressure. Looks like its from some genious' previous oil pan removal cause all of them were still on the pan where they were supposed to be. Now my question is should I prime the pump before starting the car? Well thanks guys for all the support.
