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

Valve clearances do not change based on time. The change based on miles/wear of mechanical components.
And, yes 150,000 miles is the official answer from Cummins with the additional statement that these engines tolerate a WIDE range of clearances with no adverse affect on performance.
