|Triple88a||It moustly smells at idle though.. rev it at idle few times.. maybe that might get the smell going. Not really a way to check the cat.. also i think the check engine light should go on if its bad anyways..|

Thanks for the suggestions. I will check the vents.
Triple88a - burnt kerosene is a pretty good description of the smell. Is there anyway to check the cat w/o taking it off?

|Triple88a||good idea..pull over and check that out when you get the smell.. I think the vent for the front diff is on the drivers side of the radiator.. its connected with a bracket to the top radiator bolt right next to the coolant resvoid. Its a rubber hose with a white cap on top of it.. run your fingers and see if you get any liquid on your fingers.. The rear vent is ziptied to the fuel filler neck..|

|4point||What about Gear Oil, it has a very distinct odor different from other oils. Mabey one of your Diff's are too full and its over flowing through the vent.|

maybe its your flux capaciter getting ready to engage .
my first thought was that it was your cat, but usually they smell like rotten eggs like BLK said. don't know buddy, like everyone said just start poking your nose around under the hood and underbody areas.

|Triple88a||Hmm i'm guessing drive it somewhat hard.... stop it and go under it and sniff around and hopefully you will find an idea where its coming from. If it doesnt smell when not mooving then it cant be something burning in the engine compartment... turn on the heater and see if you get some smell that way..|

|my98tj||could it be the catalytic converter breaking in? don't huff the exhaust pipe, but does it smell like that when it's parked and just idling?|

Hmmm, I would think that if it just has a few hundred miles on it then it would be just some residual spillage.
I'm not 100% sure what I even think it is.
Hey Tiny, did you ever get that smell to go away on your rig? Weren't you having the same time of thing?

No sulfur or rotten egg smell. It is more of a petroleum/chemical smell with a little bit of a burnt smell to it.

|1BLKJP||Hmmm, So it doesn't smell like rotten eggs at all?|

I am trying to diagnose an unsual smell in my TJ at medium speeds. The smell is like roof tar mixed with pesticide. You can smell it above 20 mph and below about 50 mph with the top on or off. I thought it might be the transmission fluid, but the dealer supposedly checked that on the recent service (3000k) and said it was fine. I am thinking of just replacing it anyway. I recently did a long haul through the desert towing a small/light boat.
Does anyone else get that smell, or have a suggestion of a cause. It does not appear to the typical new paint/coating burn off that sometimes comes with a new vehicle.
I would appreciate the groups' help. I have an 06 X 4.0L auto 3.73 with 06 Rubi wheels and MTRs (31s) 3K miles.
