Just performed boost leak test... heed help..

[Newlogics]

Ok, so here's what's up.

First of all, there is hissing sound in the intercooler area, which is leading to the intercooler as possible faulty spot, but there is another, even stronger hissing sound in the intake manifold area. I tried to determine where it is comming from, but couldn't. It seems to come from underneath I guess.
What could that be ? Is that normal, or is it the gasket ?
any other suggestions ?

Not normal. Could be the throttle body gasket or intake manifold gasket. I've had to replace my throttle body gasket between the T-body and the intake manifold. I have also had to replace a friends intake manifold gasket (not fun).

I tried to pinpoint the location, but it's just omnidirectional sound...

I hope it's T-body gasket, 'cause if it's mani.... that's a lot to f^&k with....
let me get this straight: There should be no hissing whatsoever ?

-Spraying soap water might help.

Good idea. Thanks.
Although it'd be a bit hard to do under the untake manifold....

Umm. Use carb cleaner not water.
