Yes, as Jhill has described. The VVEL was designed with the idea that its components surface coating ( Nissan calls it Diamond like coating) would actually interact, on a molecular level, with the Ester oil and provide a "constant" film of lubrication to prevent this "tick" "chatter" "interference" or what ever you like to call it.

It was more apparent in the Infinity Cars with the VQ37VHR engine, because the cars had better sound insulation than the Z, so the theory is, those owners picked up on it versus us deaf Z drivers.
