Easy: You need to rebuild your BOV/Diverter Valve with new plastic seals/gaskets. They are a couple bucks and can get them from Pelican.

Here is the Link [2 per car]: Porsche 911 Intake System - Page 2

Thanks for the tip, appreciate!!!!

By the way, when each time I start or off my car, the pressure release valve make a click (ka-la) sound, is that normal?

Once you replace those gaskets, you won't hear the "click" any more. What you're hearing now is "metal on metal."

Look at this thread and see pictures a couple posts down...
