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.
You only need to do it at 15000 miles or annually. I run oil analysis on my engine and at 12,000 miles the oil showed good for another 10,000 miles but I change annually per Cummins guide. I do run 5-40 Mobil 1 Turbo Diesel. But it's your money and you can spend it any way you want. I would rather by fuel.
