Would it be at all beneficial to lubricate these? Harden steel on aluminum doesn't seem like a long lasting relationship to me. i have 1 of 3 things that i could possibly uses or that i think would work. lanthanum grease, Mobile one synthetic grease, and polyurethane bushing grease which i doubt would work because its pretty sticky. i want to see if anyone had some input or could elaborate on this

 

That green color is from a Teflon coating.

Lubrication not recommended due to the tendency to attract dirt.

 

your right,but it "holds" dirt, rather than attract it. BUT i think its safe to use on throttle body shafts BECAUSE there should be NO presence of dirt anyway...its filtered.

 

Okay, "hold".

But, there is a slight leakage from outside to inside around the shafts, which does "attract" dirt, and isn't filtered.

BTW, we are talking about a q-jet, right?

 

shouldnt there be some air tight "o-rings" of some sort placed inside the throttle body housing to keep outside air from leaking into the "main stream" of air?? if not, then it would make a maf sensored car under perform, if not have drivability issues..

and idk if hes talkin bout a quadjet lol, iv been picturing a tpi setup in my mind the whole time. haha

 

No, there is not. What little leakage there is past the shafts (very little, but enough to bring dirt with it) is compensated for in the tuning. A computer controlled carb would compensate for it automatically.

And what forum are we in here?????

 

ahh i see. and haha i just noticed that its a "carburated" forum. oops lol

 

talking about a edelbrock 4bbl 600cfm carb

 

Look through Edelbrock's owner's manual, find the part about "lubricating the throttle shafts" and get back with me. . .

 

BTW, that is the "right" way to reduce wear, hard on soft. Think crank bearings (which, admittedly, are lubricated - but that's beside the point).
