Question

If I remove the belt to my smog pump, whats the worst that can happen? It started making an ugly rattling noise and I think its toast. But other than to get through emmisions, is it critical?

My belt is off right now, has been for over a year. I have to test mine next month so I'll put another belt on it just to take the test, then I'll cut it off again. It won't cause you any problem, all it does is inject air into the exhaust. Mine was starting to make a little noise too.

If you still also have the cat. converter you may end up fouling that. The injected air keeps the burn process going to reduce carbon and soot (the very things that will plug up a cat).

My belt is off also. I passed inspection without it, but for a "technicality" low-mileage-driver reason.

I doubt it will kill your cat. The way I understand it, the pump increases the availability of additional oxygen (O2) molecules, in the cat, to combine with the bad CO molecules to turn it into ok CO2 molecules. The bad CO doesn't stay in the cat to clog it, it just comes out as bad CO.

If your engine is running so bad as to pump ridiculous amounts of HC, and possibly CO, into the cat, then I understand that could kill it. But then, in this case, it wouldn’t matter if your pump was working or not.

Don't know if it's a fact, but my manifold and cat line check valves seemed to degrade without the air being pumped through them. Or, maybe it was just time for them to die. You might want to keep an eye on them. You don't want those hot exhaust gases, from the manifold, being directed toward you brake fluid reservoir. Ask me how I know!

When the old pump seized up, the belt started smoking so I disconnected it. The eagle-eyed emissions guy spotted the missing belt, but a new pump was less than $50.
