Cummins ISC 350hp Valve Adjustment Schedule
I have a cummins ISC 8.3 350 hp engine. I know on Cats, they recommend a valve adjustment at 30,000 miles. What is the schedule for the ISC. I'm just shy of 30,000 miles. Thanks Brian

The Cummins guy told me 250,000 miles (425 hp ISL).
(2008 Dynasty with just shy of 70,000 miles).
