Thank you all for the information that I am letting my truck die slowly of black lung [yuk] caused by the EGR system. I sit here on the fence weighing the loss of warranty coverage in exchange for a better running engine at the end of the warranty. It seems that the warranty could get me through 100k and then I am left with a fouled engine. I have just over 1000 miles and haven't had any issues. My 6.7 runs like a watch. We don't have exhaust testing for Diesel in VT over 8500# so a full delete is an option on my 2500. I do my own mechanical work but the computers intimidate me. Those pictures at the beginning of this thread got my attention.

You are not alone Kurt! Even my wife was amazed at how bad those were. I keep saying that I want to put more miles on before making the jump - then I see those and yesterday I saw how black my oil was with just 4000 miles on it. I had a old diesel years ago and I know how black the oil gets, but this chage was much sooner than I normally do my oil change (we are preping for a trip) it was wasted! It cannot be good for the life of the motor.

I changed my oil at 500 miles and checked at 1,020 miles and it is black as coal. Routing the exhaust gas through the intake is just wrong. I will be reading through all the deleting posts as time permits. I [dummy] didn't know about EGR systems, so now my education begins and education costs money.

I am also weighing the pro's and con's on the deletes as I have 1900 miles and one week in this truck. Just how many ppl have had an engine issue in the first 100,000? I traded in an 07 quad 1500 with a 4.7 that never had any issues. 113,000 miles, 2 sets of tires, one set of brakes and a battery. If this truck is as good as my last (better I'm hoping) it should not be an issue. I also have no inspections where I live.

I would also be interested in any warranty claim statistics related to Cummins 6.7 engine and transmissions before rolling the dice and going without the warranty. The more I think about this it seems I have to remove the EGR and DPF or have a huge repair bill possibly the day after the warranty expires.

I hope the Smarty Jr disabling my EGR helps the carbon build up! I did the Smarty around 5k miles, so there is that... The fuel dilution from the DPF regen ain't so easy to get around while keeping it easy to get through smog checks.
Not to highjack, but I just picked up a TDI Golf for commuting (45mpg so far!) and with all of the smog and no DEF the oil stays a nice clear golden brown --- WHY?

The old glow plug VW Rabbit I had back in the 90's made the oil black pretty fast, but I just did my first 6000 mile oil change on the 93 Cummins, and it looked like ordinary gasser oil at that mileage. I suspect it'll pick up a bit more soot when I turn up the fuel, but black at 500 is ridiculous.

I thought it was the third injection event on the 2004.5 and later trucks that turned the oil black. I have a friend with a 2003 2500 5.9L HO and the oil stays much cleaner. Someone please correct me if this isn't true.
[duhhh]

totally different animal on the 6.7 with DPF. an additional injection is done to heat the DPF to burn off particulate soot. i was just wondering because the VW has a DPFas well, but the oil stays clean

after reading this thread i did an oil change and got curious. well what i found is not good. truck is cab & chassis 3500 with 15,000 miles. mixed driving and pulling skid steere. this is what mine looks like.

2,200 miles and no trips less than 30 miles each way or much idling on my new Laramie.

You have two choices sell the truck now or full deletes as there's no hope. [laugh] I think I know which way you are leaning.[coffee]

I just had to remove the exhaust pipe from the air intake [laugh] I'm almost done deleting the exhaust cooler.
