Hmm, The more i listen to this the more I feel that the classic failed VANOS 'rattling marbles' sounds isnt actually real. I think its a result of something on the pelican case rattling around. I tried to isolated it as much as possible so I will check into this tomorrow. Regardless the chattering sound is spot on what I always hear and is real, but this marbles sound is not something that I usually hear running the car with the hood up perhaps the VANOS is somehow not shot...
