1g throttle body swap...leaking on blt..shaft seals?

[onefast2gdsm]

So I just swapped to a 1g throttle body that my buddy gave me. It's leaking at the rear of the throttle body and I can't figure out from what. I sprayed soapy water but I'm not seeing any air bubbles. When i hhit the throttle lever, the tone of the leak changes. Is this shaft seals?

Yep....


Throttle Body O-Ring

Do it the right way and replace them with proper seals and not o-rings.

Check the o ring gasket on your ISC motor as well. That is extremely prone to leaking if the seal is bad.

Does it matter if I use orings?

Does it matter if I use orings?

yes, it'll leak if they're not the proper size they'll leak, which is why you should buy the set from extreme psi.

I personally have read about too many people who still have a slight leak after using o-rings. In all the throttle bodies I've rebuilt, I would always use proper seals as I never want to tear it back apart right away.

I used o-rings from Lowe's and they ended up leaking as well.

Just fill it with RTV, problem solved

Anyone know the correct port on a 1g throttle body to tap the boost gauge into? I have it on P but its not registering vacuum at idle
