Nothing wrong with the system, everything working fine, regen numbers ok too.

-- gotta love these "Environmentally Friendly" that dump and waste fuel into the tail pipe -- ehemm...; trucks eh?

Thanks Rawze I think your right on and I thank you for your service.
I guess its obvious how old school I am! [70 years old]
Last cummins I drove was A shinny 290 in a 1973 road commode!!
Rawze this website is worth its weight in gold!!!
I among many owned CATS from the 425 to the MBN to the Ascert These trucks got old and we got old!! I myself traded in a 2007 w900l kw on this 2016 Peterbilt 579 with lots of warranty and 7 miles per gallon isx cummins good running engine even with the DPF just trying to decide when to ------ it!!
I don't have insite but I have mechanics all who have insite!!
we keep it clean or try to! replace anything that needs replacing we just couldn't figure out why on rare occasions I was blowing out smoke.
I pick up loads of zip boards in a warehouse that's kept at 80 to 90 degrees in northern Maine there is quite a difference in temperature out side.
And this past week I sat in traffic a couple of hours it went from 34 degrees to 28 degrees in 2 hours the smoke bellowed out until I got up to speed.
Thanks to everyone hope to learn more before I give up and retire.
