    No I’m trying to see if the guy was somehow right because there’s a whole bunch of people on the forum doing the same thing.And….I added a gallon of gear oil to the motor yesterday so that’s another reason why I have my fingers crossed.

    I get that it goes against standard practice but why was a premier Cummins ISX rebuilder impressed with the internals? The man standing on the right with the maroon hat is one of the best Cummins ISX rebuilders in the country.Even he was skeptical before disassembly.
