actually it's the vvel. The swinging lever arms on top of the valves that go back and forth generate a lot of friction and heat. That's why the vq37 generates proportionately more heat than many other engines, and that's part of the reason why nissan uses diamond like coating and nano particles in ester oil, to try and reduce the friction.
