It's Vacuum leak. I can hear it at the back of the engine when I open the throttle a real quick whistle. Can't pin point it. I smoked it and can't find a leak. What's the chances it's the intake gaskets? Alot of the vacuum lines are buried under that crazy intake.
Just a hunch, could it be the line running to the brake booster? There is a lot of vacuum there.
Check right where the brake booster vacuum enters the booster. move that connector around to see if you hear a difference in the vacuum sound. Also, check the vacuum source connection for that hose, and, the booster itself could develop a leak.
