1G Boost Leak at Throttle Body, recommendations?

[Panchoelkatch]

Found a huge boost leak coming from the throttle body area (Guess that explains my full boost coming in near 6500 RPM, if I was really even hitting full boost.) Anywho, wont go past 10 PSI with my 120 PSI Compressor, because of this TB leak. Well I've researched and found that the TB Shaft seals go bad and start leaking after some time, so my TB is off the car.

Its a 1990 Throttle Body so, it's different than the other TB's that Ive seen. My question is, have you guys had any luck using O-Rings as replacements for those seals? Were you able to get rid of these leaks using O-Rings?

Any tips on installing the throttle body Gaskets (2)? I ask because, I was thinking about maybe putting down a very thin bead of RTV than laying the gasket down, anyone had any luck with that?

Thanks, and any other tips on rebuilding this TB would be awesome, because I can't find a write-up for the 90 Specific TB!

I did boost leak test, and I heard massive air coming from the TB Area. Turns out I have a leaking injector seal. Pissing like an untied ballon

Reviving an old thread, but I am very confused. I used a fogger at work designed for BLT and the only leak to be found was from the TB. After inspecting it, it looked like the smoke was coming from the TPS. I pulled the TB out, again, and the TPS looked fine. I am also experiencing a higher idle, around 1100, and just kind of assumed this boost leak from the TB was the cause of that. I have a 98 GST with a 6 bolt in it, anyone else experience this issue?
