Hey what up guys,

Heres my situation. I got serious a vacuum leack in between the throttle body and Intake manifold. I tried changeing gaskets but then I found a second problem. I tried putting on a new gasket and it did not fit right. I dont know If I got the right gasket but I asked for a 94 LS motor. Any ways I wanted to show you guys my manifold throttle body so that you guys can assist me with getting the right gasket. Or the right throttle body. heres the pic





and heres the setup
b18a1 motor with b18b1 manifold and I think I got a b1 throttle body (not sure)

man there all pretty much the same. the bolt holes are all the same for b,d,&h series motors, the only thing you would have to worry about is bore size of tb and make sure that the fitv port and iac port line up on the gasket

the bolt holes on the gasket did not line up with the bolt holes on the throttle botty

then i would think that you got the wrong gasket

yea there has to be something wrong cause if you ever see a throttle body for sale it says it fits b,d,&h series so somethings not right. did you turn the gasket to make sure that you had it on right?

well at this point I would just try to get another gasket from a diffrent car like a gsr or something.

you have to make sure it has routing and gasket for that fitv on the bottom...

Also have to be sure it's not pulling in air...

not all t/b match up to every intake...
