as from previous posts i have been running into problems here and there with some repairs. Before we started repairs my oil pressure read about 65psi at idle and pegged out at 80psi under load. Now since rear seal repair, its pegged out at idle. This seems high to me after reading other posts of oil pressure on here. How do i go about verifiing the pressure. We test drove it yesterday, about a 1/2 hour of up and down hills and holding rpm across the band, no leaks and car runs good.
