Any one know anything about resetting the valves on the newer cummins? I was told that this was needed at around 80-100000 miles. Anyone here of this? thanks

Checking them wouldnt hurt.. I would just jump right in and ajdust them unless they are really far off.. I think the specs are the same as the 2nd Gen Cummins- 0.010" on the intake and 0.020" on the exhaust..
