If you look at semi trucks or heavy equipment, farm tractors ect, you will see the "black sludge" running down the outside of the exhaust stack. Once a heavy load is applied the fuel will burn off.

I certainly don't want excess "black sludge" entering the intake hence the EGR revolt.

I had to pick my son up at school today. Perfect to experiment with truck ideling for a while since I was early. The outside temp. was 29 F. I let the truck idle about 15 min. and the pyro said 325 F.
So then I flipped the switch for the elevated idle of 1200 RPM, and let it run there for 15 min. It climbed to 350 F on the pyro. It did this within a couple of minutes. But I was hoping to see the temp. climb higher.

My fear with a long idle is that you'll gunk up the EGR valve or worse an EBP, which will cause turbo surging or unstable idle. The 6.0 has a lot of unconventional technology on it. I've heard about wet-stacking problems before. I don't know about the 6.0, but if you are going to put a decent load on it after the idling with most equipment you'll burn it off so I am told. Officially, Ford says it's a no-no.
The most I've ever let mine idle was about an hour, and that was when I fell asleep with it on while at a rest stop...long story. I didn't end up with any damage. Eight hours is another matter, though. A bad glow plug module must be a real bugger. I suspect you must have a short taking place somehwere else in the truck's wiring that is causing it to blow modules. That's just not normal.
24 degrees. Damn. I was going to suggest you plug it in ang maybe get it warm enough to get going. I don't think the block heater can pull that one off. There's too much electronics and sensitive stuff to get it to go the old-fashioned way, too. I'll keep my mind on it, though...

My concern, according to the article, is not if anything seems wrong after you burn it out, but the long term affects that would accumalate over time. Then all of a sudden, kapow.
Of course it also state this usually occurs when fuel quality is low. So, who knows.
