    102 mm LS Throttle body vacuum leak

    I installed an aftermarket LS style throttle body and after the first test ride of only 16 psi of boost I heard a squeal and went back home to check it out. After only one low boost pull the throttle body is leaking around the shaft. How do you keep this from happening?
