Wow, I don't know wtf that is. Can you hear that just standing next to the car, without shoving a camera up by the cat?

The sounds I've been talking about are just subtle repetitive ticks, like a metronome synchronized click-track, that are completely stable (at a given rpm). What you've recorded is something very scratchy and erratic...
