What is going on when at an idle the smell of arm pit funk (best i can describe it) is comming from the CUMMINS. I take showers regularly so it is not me. I have a 03, 05, and (2) 06's and they all do it time to time. Just wondering, Thanks

 

What oil do you run?

Rotella-T (ro-smella) is famous for this. Mine smells (but I like it) after an oil change for a while.

 

Is the A/C or defrost on?

 

See, I was not thinking in that direction.


Is it coming from the engine bay, or is it inside the truck? Where are you at when you smell it? Give us a little more info...

 

HAHAH I know what ou are talkign about I have a 06 and man it smell bad. I do run the Rotella-T but I always think i have a a massive oil spill going on couse truck smells bad ...

 

Mike just be your cat getting up to temp. They have a distinctive dank smell to them when they're cold.

 

Is the fuel old by chance? The reason I ask is I had some fuel that has been sitting around for a while, I dumped it in the tractor last weekend to get it used up. Whew.....that stuff stinks, kind of like bad B.O. mixed with diesel exhaust. Runs ok, but sure does stink.
