I'm not doing a total engine teardown, just going to have the rear main leak fixed by a local mechanic and figured I'd ask the professionals on here so what to use. Truck runs fabulous but that leak is really annoying. It sat for 18 years in my garage until last fall I got it running correctly but I have no experience with the rear main work. Or do I drive for a while this summer "Live in MN" snd see if it swells back up? Or do I dare use any leak sealer like Blue devil? Or you tell me! Thanks
