Yep. That's it. I really hope I'm wrong - but it's starting to seem like something bigger like valves or rings - as Thumper600 said. IIRC, I read that these cars are known for 'ring leakage'. I hope I'm wrong and that it's something relatively simple.
Would issues in the whole VANOS pump mechanism / hose lead to this? I'm just thinking out loud, here.
