Re: oil pressure
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.
http://www.3si.org/forum/showthread....e+oil+pressure That thread might help as well (but I didn't read it all yet)

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