Hi all,
Please throw out any ideas you can think of, cause this is baffling me. I did a boost leak test only to find a loud hissing near the intake manifold. I ruled out the intake gasket since the 93s come with a metal one. The only other option that crosses my mind is the injector o-rings and insulators. I change both the rings and insulators and boost leak test again. The same hissing comes from the same place. After closer inspection, you can actually see the spray pattern of the fuel coming out of the head near the insluator. So, figuring it's a bad injector or something, the rail comes out once again and I swap in a spare injector with the new o-ring and insulator. One more boost leak test proves that nothing has changed. The spray is clearly visible when you duck your head in there. It's only around the one injector, second in from the driver's side. You can even get a smell of gas at a light sometimes. I know this can't be safe, but have no other ideas. I mean even if the fuel rail was warped or something, wouldn't it affect more than the one injector? Any suggestions would be greatly appreciated. Thanks.

Is it possible that the o-ring / gaskets just aren't seated or sealing right? I can't think of any reason why that wouldn't fix it.
