anybody know why i smell diesel through ny vents

For some reason whenever my truck is idling i start to smell raw diesel through my vents. if i put it on max ac and the air is drawn through the cab i dont smell anything. i only smell it when its idling, while driving i dont smell it. and its odd too because i really only smell the diesel through the vents, not really outside or anything. any ideas? its startin to freak me out.

look for a cracked exhaust crossover pipe at the turbo or flanges that will crack and cause a leak. thats is very common on any of the powerstrokes. there will be soot on the fire wall. also could be a fuel leak in the vally if this is a 7.3. If you would fill out your sig it would help alot just knowing what the vehicle is that you are talking about.

Its an 06 SD with the 6.0. So where is the crossover pipe located? How expensive is that to replace? Thanks

The cross over pipe is what feeds the turbo from each manifold they will crack at the bellows ( short pieces of pipe that look like they will flex). they will crack there and also at the flanges where they are held in place to the turbo by band clamps. could also be your exhaust pipe flange is cracked. they arent to bad price wise get aftermarket parts they are less expensive.

The smell doesn't resemble exhaust. Its exactly like when your fueling up and you smell the vapors of the diesel. And only at idle. Does that change anything? Thanks for the help.

No its definitely. Diesel. And no I haven't checked that yet. This may sound stupid but where exactly is the fuel filter? Also where is the fuel pressure regulator?
