My smog pump has been making noise for a few years now, and I can feel the pulley is loose, it wobbles... it still works, but I don't know how well..

I was at the junk yard the other day pulling a tensioner bracket for my car, when I noticed the car I was pulling it from (89 2.8 bird) had no smog pump... it just had a metal rod that bolted to the side of the engine somewhere, and a pulley was mounted on the end of it, a few supports kept it in place... would this be my best option, or would my car run like crap if I removed it?

I guess if I removed it I'd have to plug up all the hoses that the pump used to affect, but what else would I be looking at? What consequences would I face, other than maybe emissions? -- I'm not too concerned really, as I may even hollow out my cat.

Thanks

 

None, ditch it!

 

should I just go back to the junk yard and snag that pulley setup, then plug the hoses, or is there more to it than that? I assume no electrical or sensors, right?

 

Does a Smog Pump really eat up alot of power?

 

I have no idea, its just that the pulley is dying on it.. or it may be the bearings or whatnot..

just figure instead of PAYING to have a new one installed, I may as well just get rid of that POS

 

I figure it was put there for a reason i would just leave it but thats my .02

 

I'd just leave it, but it's getting REALLY noisy... I have a feeling it will seize up sometime in the near future... taking my belt with it. I'm basically wondering if I should replace the pump, or get the smog deletion setup from a junkyard...

 

Yes when they are old and worn.

Brand new they are probably pretty easy on using up power.

smog pump is like a roots blower. cammed round wheel in a round aluminum housing. With 3-4 fins that drag and scrap on the walls to push air around. I had one apart once and it basically looked like that. Steel fin dragged across aluminum and no wonder it seized up like a rock. Had to beat it apart, there was no way or chance of making it work again. It seized.

But brand new I bet the tips and surfaces are coated with something. Probably like a roots blower. Teflon tips on the screws.


Ya only "need" one of your in a smog check zone.

I had one but took it off. My 86 has the easier Vbelts and the 86 auto trans cars had no smog pump, so a shorter belt was simple to find and install.

 

any advice on what I should do with all the vacuum hoses that attach to the smog pump? simply plug them with golf tees or what?

 

When mine seemed to have fallen off the car I had to make a new alt bracket to keep the next size belt tight. I also had to route it slightly different.

The vac hose I plugged with a screw.

The hole in the manifold I found some brass fitting, but it kept backing out on me. I ended up using some type of muffler repair putty, and jamming all that shiznit in, and heating it with a propane bottle to make it stick.

Wires I just tye wrapped up to something.

Mine is still laying around somewhere, at some point I would like to take it appart and see what it is/looks like. More projects then time, and its last on my list.

 

Wish I could make an S/C out of it!

what's wrong with keeping the belt I have, and using this setup I saw?

 

I've never seen such a setup.

 

I saw one on an 89 RS not sure of the year i was looking at his enigne and it took me a while to figure out what was missing in that spot.

 

.

 

How exactly does a smog pump work to lower emissions?

 

well if anyone comes across one of them gizmos, ****** it and let me know

 

I may have to go snag that off that car... I may have to replace the pulley though, as its been in the rain so long.
