With the Ethos on it, read 75-85. Its the new High volume Melling pump that is supposed to fix these issues on a 145K mile motor. I just knew the problem area of these 2007 blocks were losing pressure when idling for a long time, which is where this started, just let it run and hear it make noise. That went to driving it home (3.5 miles) to see if there was still noise and had me questioning oil pressure first.
