Should the tailpipe be black?

I was staring down the exhaust pipe of an International with a 466 and DPF system on it the other day. I just noticed that the pipes were clean as could be, only water and rust on the inside of them. I could also see the backside of the DPF, and it looked brand new. Not even gray. Nice creamy white color. The truck had over 50,000 miles on it. That is what I expect from a stringent emission control of particulate matter. Black soot is particulate matter right? Or am I getting something wrong?

I let it cool off today when I got home, sprayed some brake cleaner up in there and used a clean rag. They look brand new. I had some soot, but I've been running it REALLY hard for the last two weeks. Will go back to a normal routine starting tomorrow and will see what happens. I'll take a new DPF.

I watch these threads constantly because inevitably someone posts something, and later they end up in my bay. Got one here now from Colorado curiously, just had a DPF replaced (Must be one of the "good" dealerships). 2000 miles later, "Customer said that it started blowing black smoke, and quit going down the road". HMMM......... No oil touching the stick, DPF plugged solid, no exhaust at all coming out of the pipes. Removed the dpf, starts and runs but smokes and stinks like overfueling. SOOO, FTE, be a "GOOD" Ford tech and replace the dpf again and pronounce it fixed (let someone down the road worry about it), or pursue it farther and repair the reason the dpfs fail (this one is good, just plugged solid).

Passed on more than you know. Warranty problems now. Truck has 103 k miles on it. DPF was replaced at 98k. Ford will ask, "Was this the same issue?". It leaves it up to me to make the determination whether the customer pays or its warranty (another reason you don't **** off your tech). I backed off and let the powers that be hash it out to see who pays, then I'll get back to work. See what kind of a mess poor diagnostics leads to?

well, is it the diagnostics fault, or just sloppy (aka, incomplete) workmanship?
is the DPF clogged, yes
is there a way to 'unclog' it at the dealership, no
so it has to be replaced, yes
done
wait.. what CAUSED the clog. injector, ??
did the CUSTOMER cause it, no
was the original problem found (documented) inside warranty, yes
was the original problem completely diagnosed inside warranty, no
is that the customers fault, no.
I think it should be easy for the 'powers' to make this kind of decision.

Thanks for the update. Mine will go to the dealer week after next. I need to get something else lined up to drive while it's there...
What that really means is I need to buy 2 new batteries for my 7.3 so I can drive "Old Reliable" while the 6.4 is in the shop...
