Wow, that is horrific sounding! Sounds too high pitched for knocking rod. Have you checked to see if you haven't got a spark plug that's backed out or blown out? That, or timing chain tensioner is gone and the timing chain is hitting the housing?
I can't claim to have heard many engines with bad vanos, but it's hard to believe that's a vanos issue sounding like that.
