exhaust smell while driving

78 cj5, no doors or top, after I drive it I smell like exhaust. Anything I can do, is something wrong, or is it normal because I'm all open. Thanks.

I know that the exhaust pipe has a seam right under my driver seat on my '83 CJ7. Mine isn't sealed so I do smell my exhaust but when I've got the top off I don't notice it. Top on though is a different story. I need to seal it up but just haven't yet. If you smell exhaust I would guess you have a leak somewhere that if found could be patched up.

IF your exhaust exits out the back.....
NO, you have a leak somedangplace.
You might be run'n on the 'rich' side also if you can smell it.

What's weird is I don't really smell it when driving, but I smell it on me after.

Are you sure its exhaust? Could it be that your hoses connected to the charcoal canister have come undone or are not there? I had a few loose hoses there also that made my clothes and the garage stink.

Your exhaust should be routed to the left rear corner of the Jeep behind the wheel. It should NOT be routed straight out the back. If it is the slip stream will pull it back into the Jeep. When in motion a low pressure area is created behind the vehicle. (Ever hear of "drafting"?) Putting it out the side allows the slipstream to pull it away from the Jeep.



You should check the whole system or leaks too, and there are other sources for gas oders such as the canister under the hood.

I'd rather be lost on the trails than found at home!

"Rich" means too much fuel in the fuel to air ratio in the carburetor. "Lean" means not enough fuel in the ratio. The grade of gas has nothing to do with it. If it's too rich, some of the fuel doesn't get burned and you can smell it.
