Hey everyone. here's one for you. Stock 88 block, Ford Racing stock spec. crankshaft, main caps, etc. The rear seal starts to leak after @ 15 minutes of idling. Motor was just put back together as well. Oil pressure of 60 at an idle, 80 at 2,000 rpm. Yeah, a little high but I doubt its the culprit here. Running a breather, no blowby, using a pcv and that's it. After it gets good and hot, the rear seal starts to leak. Both seals used were from Ford Racing and Ford and both leaked after @ 15 minutes of running. Seems to be coming from the exterior edge of the seal, not seal to crank. Nice steady drip. Seal installer was used as well. Even squirted some silicone on the edges when the second one was installed. Block was inspected for a nick or scratch as well. It's Any thoughts? Anybody have a part # for a seal with a slightly larger o.d. ?
