    Even paccars are flat surfaces with sealant between and they dont leak. Cummins loves those steel gaskets and they always wear into the aluminum. Keeps our local machine shop busy resurfacing.

    And it's not even rtv? Just anaerobic. That in itself is impressive to the design and the machine work.

    Paccar tends to like quite a bit more bolt stretch/load than Cummins and the ISX block seems to flex towards back a lot.
