While you are there, you may want to remove that butterly in the intake... the little bolt & nut rattles loose over time & can cause major internal engine damage.
Aparantly it is there for a reason. We saw on Alex Le Roux's 4.8 that it increases torque at a certain rpm. Thys got heaps more torque with it working than disconnected........ Nissan actually did some development on that item

I wonder if this could be the cause of the rattling/tapping sound on my 4.8? I suspect it needs valve clearance adjustments but heck maybe I will be incredibly lucky and save myself 15k or more !
When in doubt throttle out !

Well maybe it should be left in, but just make sure its tight! I have personally seen the broken cam from bits going through the engine.

I'm pretty sure that the butterfly is there to shorten the intake runner length at low rpm to improve torque at low rpm.
