Oil pressure should be around 12psi at warm idle ~700rpms, and increase linearly with rpms, to about 70psi. 75 at idle is WAY too high. I'd start by swapping your pcv valve, and checking the hoses for blockage.

That thread might help as well (but I didn't read it all yet)

Something is deffinatly very wrong. Something is plugged and not letting oil through.
