Here's a question for you about an incident I had today.
2008 Dodge Cummins, 6 spd manual. It has a DPF delete. It uses a chip to reset the computer each time you start it.
I was coming down a long, steep hill. Pulling a trailer that grossed under 2500lb. I'd been averaging 30 mph, pushing against the compression brake most of the time, usually in 4th gear. I'd gone 15 to 20 miles like this when I got a huge puff of WHITE smoke out of the exhaust. It was 1/4 mile before I could pull over and by that time it was clearing up. By the time I got stopped, it was pretty much done. It never did it again. The oil pressure and temp were fine.
Any ideas what could cause that? Could the compression brake cause it?
