boost leak at TB

[stevek]

I did I boost leak test and found these leaks... throttle body gaskets, the Base idle set screw, and 3 fuel injectors are leaking (so i will get insulators, and maybe O-rings). But, Im not sure what exactly this is, but it was leaking alot of boost...

The only thing i could think of was a cold start activator. At the bottom of this there is a little hole where alot of boost is leaking. It almost seems like it is meant to have air come out there?
If not, are there seals inside of this that could go bad?

I appreciate any help.

Throttle Body O-Ring

So just to make sure. The throttle position sensor should not be leaking any boost at all correct?
And this leak around the sensor is caused by bad throttle body orings.

Thanks for the help.

Correct, there should be NO boost leaks near the throttle body, or anywhere for that matter. There is no part designed to intentionally leak boost (ya, ya, mbc bleeder hole).

Yes, the boost leak is most likely caused by bad o-rings. Pick up a new set here and replace them using the link I gave you earlier as a guide.
