    Just make sure the membrane is not shot.

    I would measure the compression in the engine, because it's been knocking like crazy if it's running 25 psi on standard turbo.
    I'd say the rings are shot because of det and it needs a rebuild.
    I've also compression tested it yesterday after a run taking each plug out when testing cylinder, also keeping the throttle fully open results were 12 bar in each cylinder
