Exhaust smell in cab?

[skippydoo]

I am starting to smell exhaust smell in my 08 f-350 and the tone of the motor has changed. Also I am getting a hesatation on occasion. Windows are up with heat on and I smell it about 10 seconds after stopping at a light. Once I get going it goes away. any ideas???

I'd look at the turbo to exhaust pipe clamp, a few ppl have had thease fail. and it's in about the rite place to wind up in the heater intake while at a standstill.

Mine did the same thing when it was new up to about 3500 miles then it went away
