Holey DPF!

[Lonestar10]

before i removed my junk i had white smoke during regens pouring out of my cm871s stacks. come to find out i had 2 cylinders leaking on the manifold. would only puff white when taking off from stop lights/signs during a regen. any time my "exhaust temp" light would be on at a light i knew it would throw smoke, also regened every 2-4 hours according to insite. had baked/tested dpf/doc and new doser with only 150k or so on them. and pretty sure theres a crack or something in the flex pipe to the can as it didnt smoke then but this winter with garbage gone and some leaking exhaust valve seals after 11-12hrs of idling smoke would come up from under cab when i take off.
