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

When I had my ISC, this was the schedule I ran close to.
Maintenance Schedule (CAPS or HPCR Fuel System)
Oil & Filter
15,000 Miles, 500 Hours, or 6 Months (I did once a year.)
Fuel Filter
15,000 Miles, 500 Hours, or 6 Months (I did once a year.)
Valve Adjustment
150,000 Miles, 5000 Hours, or 4 Years (Coach was a 2001, I had them checked once after 2 years, found only one needed adjustment.)
