Smell???

[bwoods001]

Only with the air on when I stop or idle I smell an oil fuel smell in the cab but as soon as I get moving it goes away??? Only does this with the ac on, any suggestions on what it could be?

Temps ok? Do you have a way of monitoring your motors paramaters? Any puking from reservoir? Reason i ask is i had that smell when my headgaskets blew. It might be coolant your smelling....

Is your CCV dumped?

[bwoods001]

All temps are good, it's almost like when I stop it vents the air from the engine compartment. And when I take off it vents the ac with fresh air.

Prob. A stupid question but what is CCV. The truck is bone stock and has 125,000 miles on it, it's has the extended warranty up to 200,000 miles

I had that smell also. Make sure you aren't dumping diesel fuel into your cooling system like I was, courtesy of a cracked cylinder head.

My coolant level is good no puking and looks and smells to be fuel free

Welcome to the world of owning a diesel.

I can have my windows up, no air or air, and smell it. It's the exhaust

Crank Case Ventilator. Comes off your drivers side valve cover, and "normally" coonects to the underside of the intake tube heading into your turbo. Some of us "dump" it, by disconnecting it from the intake, and routing a hose to dump it under the truck. This is meant to keep crank case oil from entering the turbo, but can create a smell similar to what your describing.

I was thinking CCV as well. Mine has been rerouted in the inner frame rail near the back tire and rarely will I smell it. The CCV smells like a musty oily smell, not so much fuel.
