I will have to do it myself because Cummins can’t help me. My second second would be if I pulled all the injectors could I not pressure the coolant system and see which one leaks and only repair that injector cup with ring insert?

I would think you could see the cracked cup. Just seems to me with that kind of mileage your just chasing your tail.
