Boost Leak

Hi guys ive got an 01 WRX with stage 1 tuning pack & its recently developed some kind of boost leak.

Sometimes its fine but a lot of the time when i boot it the turbo starts pulling & then it stops & you can hear a dump of air on the drivers side. The dump valve still works as it should.

I thought it was a cracked pipe but like i said sometimes its fine so surely maybe a seal is gone on my turbo.

Any ideas?
