6.7 smoking?

[HazMat Neck]

I traded my 06 6.0 in yesterday on a 2011 6.7, new last one on the lot. Hit 950 miles today, and did my first oil change. Driving home from my granddads shop i noticed a new tapping noise which i am assuming is the type writer noise everyone is talking about. But my concern is that i noticed under about 3/4 full acceleration im getting a cloud of smoke. Not sure what color it is yet, i live in a pretty rural area and hard to tell at night the color. Obviously i have full factory war on it still, and a excelnt relationship with the truck shop at my dealer. But i was wondering if anyone else have had this issue, or any ideas what it is. Or is this normal for this motor. My 6.0 never smoked at all, so just putting it out there. Thanks in advance.

Yep it sounds like you have the type writter noise alot of us get after an oil change. Should go away after some miles. Do you know if the truck was in regeneration when you saw the smoke, that causes alot of heat and could be burning off some of the newness. Just keepan eye on it and no a stock 6.7 should not smoke.

mine smokes...but since im deleted, its a black cloud when I step on it haha

Ya its not normal for a 6.7 to smoke stock.. like said above ^^^^ maybe just wearing of the new but keep an eye on it.

Yeai didnt figure it wouldnt with all the newer emmision crap. Got the 6.0 down pretty good, but this is our first 6.7. Pretty impressed so far with it. Deff a diffrent beast.

It should not smoke...especially within 30 feet of a door to a business. I would have a talk with it. (couldn't help that response...)


Watch it during the day, if I noted smoke I would try to duplicate it with a tech. Also watch your exhaust tips, they should STAY clean.

I have 12K on mine and was told by the tech when having my turbo replaced that soot in the tail pipe was normal. I thought they should stay clean. I was told by another tech that my DPF is most likely cracked and that is why I have soot in the tail pipe. He said there is no performance loss in the engine, its just the emmissions crap not performing like it should.

A cracked DPF sounds correct... i would either have it replaced under warranty, or if your going to tune, go ahead and do the dpf delete
