weird boost prob

[Munki]

Im now having a weird boost issue with my car. Everytime i push it hard I hear this clack noise and after that the car doesnt boost at all. You dont even hear the bov anymore... Once I shut off the car and start up its fine again, but it'll do it again after a few min. having waY too many probs with this car now... lol

Manifold to turbo gasket...Nuts are loose or you blew the gasket
could also be the manifold to head flange gasket depending on type...paper gaskets sound different the multi or copper
