It unlikely that your intake manifold is "leaking." Youre probably hearing a hiss from a vacuum port or hose connection that is loose. The intake manifold has three gaskets, one for the throttle body, one for the Idle Air Control Valve and the rear one for the some coolant/vacuum lines. Try hearing from either of these spots. Check to see that all hoses are not leaking. Check for obvious signs of cracks and such. Good luck on the find.
