Good Luck Pingpong! I'm following you on this. Maybe get insite then read the engine lights. In one of Rawze's videos he said that most of the time it isn't the EGR cooler, not saying it wasn't. But you have a maint free cc filter right? If not cummins has it.
Maybe an oil sample? In addition to pressure test. But I hope it is just some moisture.

If you don't have many tools, you can get a case or a set from Home depot or someplace for maybe 2 or 300 dollars. It's good for the simple things on the road.
