The pressure converter replaced was for the big turbo. I had lost all power above about 2000 revs. The one that's only fixed with one screw is the one nearest the bulkhead, which I assume is for the big turbo.

Interesting that you had the noise before and after replacement, suggests that some other faulty component is causing the PC to make the noise. All was completely silent with mine until recently.
