exhaust smell

I can't go anywhere in my 83 CJ-7 without smelling like exhaust and gas. Is this a problem with all Jeeps or just mine. The cab is well sealed, but the glasspacks are rotted out. Any suggestions?

Re: exhaust smell

uhm lets narrow down a few things.. Glasspacks rotted out? Well that could lead to smelling the exhaust? Maybe? Just my thought.. good luck

Re: exhaust smell

Well, muddynut, I'm gonna have to agree with you on that one. I'm gonna recommend replacing those glasspacks and seeing if the smell dissapears....

Re: exhaust smell

Make sure the exhaust exits out the sides (rear corners are best). A jeep's aerodynamics (HA HA) creates a vacuum in the cab. The air rushing under the body or over the top of the windshield wants to jump into the cab, bringing the exhaust smell with it.

Re: exhaust smell

Damn! That vacuum in the cab tidbit is interesting. I've always wondered why and from where those breezes are rushing in. Not only does it stink in my heep, but it's damn near impossible to keep it heated in the winter with all that cold air rushing in the holes in the floorboard. Thanks, DEEP.

Re: exhaust smell

Well lets look at this from a logical eye. The cab is well sealed but you smell like gas AND exhaust when you get to where you are going. Not good.

First- Both the gas and the exhaust smell must be leaking into the cab area from somewhere, right? You must have a leak in the body. It may be up at the firewall at one of the factory holes. Check there, seal with silicone even if you don't think that it is the cause.

Second- You must have gas leaking from somewhere as well. Is it at the carb or the fuel filter or is the line cracked or is the fuel canister bad or not hooked up properly or?????. Follow the fuel system from the front to the back. A fuel leak someday could lead to a fire when you least expect it.

Third- The bad glasspacks may be the culprit but, do you have a cracked exhaust manifold? If the you have an air leak at the firewall, a cracked exhaust manifold is going to let fumes into the cab, same with a gas leak at the motor area.

Just Some Thoughts!

Re: exhaust smell

Does your jeep run real rich? Mine does and I always smell like exhaust too. I can walk in the house and my wife says "ewww, you smell like exhaust!". My father in laws CJ-7 is even worse, his carb needs rebuilding. My jeep is odd. It runs rich when going slow, so around town it smells. On the highway it runs lean, no odors, but starts to heat up during summer. Does a catalytic converter help with the odors?
