Air leak, Vacuum or gasket?

[blacklabelskim]

So ive been messing with my e30 for a couple of hours and i cant figure out what to replace. I have this really loud air leak, Where im getting almost no suction from the air boot. When driving i can feel the loss in power. I sprayed carb cleaner all through the vacuum pipes but it only revs up in this area. I dont believe there's a vacuum line there, So could it be a bad gasket? or cracked intake manifold?

Could be bad valve cover gasket, intake manifold gasket, or injector oring

A smoke test will tell you exactly where the leak is. With the engine having a leak bad enough to hear you will have to repeat the smoke test after the initial round of repairs to find the smaller leaks.

I borrowed my friends smoke machine and narrowed down all of the cars vacuum leaks instantly.

This was the car... epic leak:
