Selonoids on shock tower?

[f8tlfiveo]

does anyone know what these are used for? My guess is egr or smog. But I have no egr or smog on my car, so I would like to get rid of these if possible. They were on the passenger side

 

[madspeed]

havent seen those things in years! All part of the smog crapola

 

[f8tlfiveo]

I figured.. Where does the line that goes into the fender go?

 

[madspeed]

i believe to the vacuum ball. you can plug that one off at the ball

 

[jcgafford]

the larger one controls the egr, the smaller 2 control the inline diverter valves to the cats or to the heads. you can block them and have codes pop or leave them alone.

Is the ball in the fender somewhere? Does the ball need to be hooked up?

I took them out already, I am swapping intakes and decided to get rid of them because they were taking up space and I wanted to clean up the engine bay a little more. Thanks for the info

Well i do know the vacuum ball is located in the inner fenderwell. Not sure how much its needed, I dont have one in my 89

 

[jcgafford]

Yes.. All gone..

i went the opposite on mine, went searching to find it and put it all back in. wit the cats gone and the smog stuff gone it may throw useless codes that don't cause a problem.did you get he egr simulator?

 

[f8tlfiveo]

Egr and thermactor are both disabled in my tune. I have my wideband output going to the input where egr used to be on the computer so I can datalog the afr

 

[jcgafford]

nice

Isn't the ball in the fender AC related?

 

[f8tlfiveo]

Ok. Thanks for your help guys. I figured I could pull the stuff off, but just wanted to double check.

 

[f8tlfiveo]

Isn't the ball in the fender AC related?

No A/C either.

How about heat? That ball is the reservoir for the blower control i.e. the vacuum operated solenoids for the a/c and heat selector switch

 

[f8tlfiveo]

I still have heat.. Better look into it I guess.. Thanks

 

[MikeH686]

Just keep the reservoir i had taced it all out the ball goes to the check valve located in the bay and that comes from the vac tree and the other side goes inside which is your main line for your selector switch for your heat controls

A vac resevior is a nice thing to have around, especially if you have less instant engine vac due to a cam.
It is just a reserve of vacuum to keep the simple stuff like vents operating smoothly in all conditions.
