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

I think Mr.Mark's about right 250,000 and 15,000 on oil change but I change mine about every 3-4000.
