Dropping the oil pan

It's a isc, about 98k miles, 2008 Pete 335, hauls dumpsters, has the dpf only, injection on exhaust.

If an isc is like the ism, I'll take your word for it. I don't need more to do at the moment, but I do like putting eyeballs on internals as much as I can for my own knowledge and reassurance.

it sounds to me like you simply not changing the oil often enough. Change the oil based on fuel mileage (or consumption) with it and not at some set interval of hours or miles. - This will keep the soot from building up so badly that it takes out the cams and other things.

Also, I would not own a modern diesel engine of any type or brand that has EGR active in it without having some sort of bypass filtration system on it for collecting soot out of the oil. - its just plain dumb not to have one of these systems on your engine, as that soot buildup is no different than sand in that oil. There's no way in hell I would let any of my car engines, nonetheless my work truck that I have to make a living with get 'sludgy' inside it. That is just a shame. - I don't own a single piece of equipment with black oil in it and never have since even my first car I ever owned,.. can't stand to see it.

I am sure the scale of change intervals is different for the ISC, but for the ISX (its bigger brother), here are the numbers...

for the ISX....

less than 5 MG -- Change your oil every 8,000 miles or so.

5 - 6 MPG -- Change your oil every 10,000 - 12,000 miles or so.

6 - 7 MPG -- Change your oil every 12,000 - 15,000 miles or so.

7 - 8 MPG -- Change your oil every 15,000 - 18,000 miles or so.

8 - 9 MPG -- Change your oil every 18,000 - 22,000 miles or so.

above 9 MPG -- Change your oil every 22,000 - 28,000 miles or so.
