I bet a dollar to a donut your seeing passive regens, and your missing a helluva lot of them as they only flash for a few seconds..

That said, good for you!! Whatever additive you're using, keep it up.. wherever you're getting your fuel, I'd keep that up, too..

If you don't idle, take short trips, or run silly fuel delivery, you can go a long time without a full regen.. the dry ash burns away nicely, that wet crap, not so much..

yea im glad it dont do it, it runs great it even blows black smoke when i get on it. my brothers pickup is the same but it regens and when he gets on it not a bit of black smoke. could some one of knocked a hole thur the dpf and left it on? i don't know but just looking for a possiblity why it don't

Unless you are monitoring EGT and regen with something like a Dashdak/Spartan you won't see the regen very often (hardly ever).
I run a DashDak and monitor both EGT and Regen. I am stock tune with DPF on. I live in a rural area, a lot of my driving is 60-65 freeway. In this environment I see regens at 330-400 miles. If I do a lot of idle and stop and go I see regens a 180-260 miles. During regen I see up to 1300 egt.
Passive regen will not keep this truck completely clean. Best way to track is to get something that plugs in the ODBII port to monitor. My truck is driven daily from 50 to ?? miles and has 154K.

So how could the black smoke pass by? i can make it smoke every time by getting on it or luggin it around? other 6.4 i see that are still stock have nice clean exhaust pipe ends my pipe and bumper always black.

[strokinpower]

you definitely have something wrong if it is smoking.

I run a CTS insight on my truck and have it watching the regen. Most of my driving is around town and a 600 mile trip every other month. Mine cycles every 3-400 miles and once on the lond trip for about 30 miles. I have never seen any black smoke from my truck even under a heavy towing. I run diesel Kleen and get my fule from the same gas station every time. 158000 miles

DPF could be cracked inside.

[travisH3]

Yup, cracked dpf most likely.

Last owner might have gutted the DPF section. It works off reading exhaust temps pre and post if i recall.

As it clogs up the exhaust temp raises on the sensor just before the DPF and then it starts the cycle. It has a post sensor to monitor temps on the outbound side, once the sensors are reading within a certain range of each the cycle is complete.
