I also tried the belt dressing. This is something a bit different :-)

So I just got back in from my meet in France so the shop had my VX for a while now tracking down this noise and they said they definitely have it pin pointed.

So it seems the Crankshaft pulley or the Harmonic Balancer has gone bad. They said they marked the old worn out rubber on the pulley and when it would stick is when the noise would occur. Sounds good to me.
