1989 Jeep Wagoneer, 360v8, 727, stock for now,
I was talking about the Gear Housing Gasket, goes between the gear housing and the block, A real pain to get to.If you're talking about the gasket on the front of the gear housing Cummins doesn't even recommend using that. Rebuilds get RTV between the front cover and housing. Of course you do have to replace the front crank seal anytime you remove that front cover. Otherwise it is guaranteed to leak. Just remember that the crank has to be totally clean with no oil on it when replacing that seal. No reason for them to have clamped the rods in a vice that tight. Nothing on the pistons and rods is overly tight. Those rods are super strong. No worries on those shinny spots.
