Vapor canister?

RollinSidewayz · Jun 2, 2004

I have a problem of the car smelling of exhaust when the windows down, had it checked out and no leaks turned up. I replaced the hatch seal since the old one was beat and I thought it might be creating a vacuum and sucking the exhaust back in the car, but the smell is still there. I heard that a missing vapor canister might cause such a problem, and I don't have one or the smog pump since I bought the car when it was in the process of being turned into a track car. Can I replace this since I don't have the smog pump or do I need the smog pump? Will it help eliminate the smell at all?

Maybe you have a small exuast leak.

The cannister is apart of the evaporative emmision equipment. What it does is take excessive vapor from the gas tank and uses charcoal to absorb it and when the engine is running the computer turns on the purge solonoid which sucks the fuel into the intake. If you remove the canister you need to do something with the line from the tank otherwise it is like an open gas tank. You don't want to seal off the tank, that could cause other problems. I guess you could just run the line directly to the intake.

I plugged the line running from the intake to the canister. But I left everything else like it was. Everything seems fine, im not hurting the car in any way am I?

Not the best plan, but you can get by with it. The carbon canister vents fuel vapor into the intake manifold at cruse. This helps richen up the cruse mixture slightly. It also eliminates the gas stink when the car is closed up in the garage or other poorly ventilated place. Don’t park you car in the garage if you have a gas fired water heater, the fuel vapors are a potential explosive hazard.

If you have emissions testing in your area, plan on re-connecting it. You won't pass the visual inspection without it.

Hmm no worries about the visual inspection.

Let me ask you then, when everyone else removes it. What all do they block off? And if what I did isnt the best plan, how the hell is removing it completely a better one? Im as confused as a baby in a titty bar. Thanks for the help.
