Red 15l truck engines are not common in my areas, but MX13 is very common here and I know what MX13 maintenance guidelines are. Since they have similar types of aftertreatment and emissions systems it makes for a good example of service intervals and what needs to be done to keep those systems and engine running properly.
OFFICIAL factory service procedures list the need for EGR TUNEUP (some stuff annually some every 80 000 miles)!

If link does not open search for " PACCAR MX-13 Maintenance Guidelines " .
dpf doser injector looks exactly like the one from ISX.
It is mentioned that def and dpf doser injector have to be cleaned ANNUALLY.
Egr cooler clean at 80 000 miles, engine related sensors also check/clean or replace when needed at 80 000 miles interval!
They even have manuals where are those sensors located, when to replace, when to clean (NOTICE - DO NOT CLEAN THOSE SENSORS USING SOLVENTS OR WATER).
Search for - " EPA2013 and Newer Air Management Sensor Inspection Guide "
and - "Air Management Sensor Locations PACCAR MX-13, EPA-13 Engine"
For red engines there are EGR tuneup videos, lots of articles also on this forum

Even if somebody lives in a place where all those mandate issues can be taken care off for good, engine sensors MUST be working properly to ensure fuel efficient and reliable operation. Also properly mandate'd modern diesel engine must not produce any visible clouds of smoke even on full acceleration, if it is then it is FAULTY.
Appreciate the intel man! I’ll give it a read and go from there. I’ve heard the paccars are pretty similar to a Cummins but never worked on one or even seen one for that matter! Cummins and Cats are the rage in my area at least in the truck industry
