Valve Adjustment ?

[RonD]

When are the valves to be adjusted, I read 135,000, 150,000, and 100,000 miles, so I am thinking when it hit the 100,000.

I think Cummins recommends 150k.

Anytime. There is no "minimum" limit, and that mileage is only a recommendation. There is no harm doing it more often.



I have found several truck needing adjustment before the recommendation.

i adj mine every chance i get, and i almost always find one that is a little out, i adj them every 20k on a stocker. even after only 20k i was still finding a 50 deg reduction in egt after a valve adj.
