Unfortunately it's the only way to access it the PCV oil catch canister.
I wasn't quite sure I should reply to your thread as it seems you're well on top of your diagnosis and, to be perfectly honest, I don't understand half that fuel trim stuff you mention above. Although, there is one thing that springs to mind regarding a vacuum leak. I think it was Spangoolies had a similar problem with his 2.0T. It turned out to be the one-way valve located between the carbon canister purge valve and the inlet manifold. No harm to check that it's functioning I guess...
