I have a 2009 6.7 2500 that i bought in august, I have 27,000 miles on it and recently i have been getting fumes coming into the cab through the vents. the smell is way worse than what comes out of the muffler. I've had it into the dealer several times and they have no answer, if i can't find the problem will have to get rid of it. any help would be great thanks
