This was an issue with earlier, 12valve Cummins diesels in Dodge trucks.
This guy sounds like he just hasn't suffered enough in the pocketbook yet to take his RIGHT foot off the floorboard!!!

No exhaust brake on this truck. But it has an exhaust back pressure regulator. It closes a flap in the exhaust to aid in warm up. It's stock. It has happened on the same exhaust valve 3 times. I'm beginning to wonder if its a weak valve spring.
