Default Boost leak help! BPV gasket?

I found a few boost leaks on my 2006 STi, and have successfully remedied 2 out of the 3. The third was the gasket behind the BPV, which I replaced with a brand new OEM gasket to fix the issue, and that did not help. Next, i took it off and tried some Permatex orange crap, let it set for 24 hours, and it seemed to work, but a couple days went by and it's failing again. Lastly, I bought the Grimmspeed gasket which was supposedly thicker (looked the same to me) and I am still having the leak.

Any tips or tricks to get this damn thing to seal? Any help appreciated! I want full boost!!!!

Thank you all.

A new bypass valve.
The flange might be warped or it could be leaking from a different part.
