Boost leak at manifold

[AWDTALON3000]

I've had this boost leak for a while now and it's driving me crazy, everything is fine to the throttle body elbow. I connected the pressure tester right to throttle body elbow, and all i can get is 4 psi for about 3 seconds.

I've checked all the hoses,and trottle body gasket, what else could it be??

It could be the gasket that goes between the intake manifold and the head.
