Throttlebody Leak

[daren_p]

I just did a boost leak test and found out that I have a leak at the throttlebody. Now because of where the leak is Im not 100% sure where its coming from, it could be the inner gasket but it seems to actually be coming from where the accelartor shaft goes into the tb. Is there a seal or o-ring there? I looked on my caps but they only showed the inner & outer & then the tb as a complete assembly. If so does anyone happen to know the part number or where I look in caps to find it?

Probably your shaft seals. While you're doing your boost leak test see if moving the throttle plate changes the pitch of the leak. If it does, your shaft seals are bad and need to be replaced.

Throttle body leaks usually occur from:
inner gasket
outter gasket
fiav (fast idle air valve)
throttle body shaft orings
