I have an 04 cummins with 7500 miles. Occasionally I get an oder when I am stopped or immediately after I shut it down that reminds me of a solvent similar to acetone. My dealer has no explanation. Any other similar problems out there?

 

do u have your crank case bypass hose routed towards the back end?? May not be THE smell - but it does cause issues..

 

Thats the ole crankcase vent fumes. If your dealer don't know that I would find another one the knows something about these engines. Some brands of oil or worser than others usually goes away after several hundred miles. Just add you a piece of hose to the end of it and extend it back further and no smell.

 

I am new to posting on forums, and now know what a valuable resource it is. Thank both posters for the info. Much appreciated!!

 

I get a strong odor when I use my windshield washer with the outside makeup air on. Took me a while to figure it out, but that was it. When I run out in the resevior, I'll try to find something that doesn't smell so bad.

 

I think you'll find that these trucks must have been designed by bloodhounds. If there's a smell to be had, then the RAM moves it into the cab to share around. Smells include roadkill, smoke, and whatever the vehicle in front has already burned.

I haven't noticed diesel smells or crankcase odors from my own truck. In fact, the 600 tailpipe odor doesn't smell all that much like diesel. What I do notice is any gasser in front of me who's really working... Nice sulphur odor just like I was directly behind their tailpipe.

I suspect that the design of the cab somehow directs these odors to the intake and there may not be all that much of a fix. Then again, it hasn't caused me any real worry and I love the truck.

 

I'll second the washer fluid. stick your nose in the washer fluid resivoir and inhale deeply.....

 

My truck doesn't make crankcase or any other odors inside the cab, however like Nord, I definitely notice when I'm behind a gasser going up a hill or something, that sour sulfury burnt oil smell is awful. I'm contemplating one of the Cab Fresh Filter kits from Geno's. They are only $59 and filter all the incoming air. Not so impressed with the looks of it, but I may give one a try.
