Hey Erik, I've just read your PM, apologies for not reading it sooner!
It's really hard to say from the video whether it's normal or not, due to the way cameras pick up sound, but it does sound a little more than the usual 1.8T tick.
You can hear the carbon canister ticking at one point in the vid, but then when you've close over the cam cover it does sound more rattly than usual.
It should be fairly straight foward to whip the cam cover off and take a look at the chain and tensioner at that end. It's not unheard of for the pads on the tensioner to break down and fall apart with age!
