New tb gaskets, still leaking horribly

[91tsitalon55]

Dear tuners,

I have a 1g and I started doing a boost leak test this week and found a huge leak from the injector insulators. Fixed that with all new seals/ o rings, then started the another blt and found another big leak on my throttle body gaskets. So I went out today and replaced both of them. Finally, I did another blt with new tb gaskets and the gasket between the intake manifold and tb is leaking horribly still? . So im kinda confused on my next step, any input from you guys would be awesome.

Thanks,

Its only leaking on the front side of the gasket nears the Tps sensor.

Take em back off and make sure they're oriented the correct way. You spin the gasket at all, the wrong way itll leak like crazy.

Make sure its sealed right sounds like something simple re do it and see what happens.

Its may be the "orings" on the throttle shaft, check behind the throttle, you have to rebuild it. There are a few write ups, part looks like these.

STM: MIL.SPEC THROTTLE BODY SHAFT SEALS | EVO VIII-IX | 91-99 DSM | 91-99 3000GT

But when I move the throttle cable while im doing the blt it doesnt change noise at all. Im pretty sure its not the tb seals. Ive also sprayed soapy water on the throttle shaft and nothing

Use some Rtv.

Ive always had my throttle body gaskets leak till i started using RTV.

I quess pull it off and check the gasket is on there right, look for cracks.

 

[91tsitalon55]

Its brand new

There is no reason it should leak, unless it is on wrong, there is a crack, its not tighten down enough, or like Spanky_Dsm said, use rtv for the extra seal.

What brand gaskets did you use I had the same problem. The gasket was clocked wrong. I used rtv on mine.
