Finally an update or rather the solution to my problem
Because it sounded like chain and the chain was looser than I would think it should be, I ordered a complete chain kit.
During disassembly I noticed, it really was a bad VVT actuator. Although it was not completely bad. It would latch, but...
Is it ok for the chain not to be snug if the engine is not at TDC? (and if so, why?)
After driving yesterday I checked the slack through the oil filler neck and there is slack (no idea where the engine is at..). Could the chain be bad although the VVT is fine (according TSB_01-012-12)?
Bad thing is, you're not really alowed to modify the car. You ned swiss papers for almost everything (even wheels and CAI), which you won't get.. But yes, the mountains are great and driving the roads is very fun. I have a mountain pass (around 1000m/3300ft elevation) almost on my way to work :D
I edited the original post with a video of the chain at TDC. It has no slack, but I can push it a bit. The valve cover has marks in it, but the chain has already be done, so I asume they are from back then, they do not look new I suppose..
