have you checked the UJ's you seem reluctant too but if the center bearing went this could have prematurely warn them and these will also give you the symptoms advised.

Hi, not reluctant at all - there were no obvious signs of the centre prop UJ having any play when I removed it to change the centre bearing.

apologies i just looked at the set up of the 2012 prop and see there is only 1 UJ on the rear the other articulating joints seem to have a different set up. 2012 Vogue 4.4 TDV8 - Current

I have a noise that is slowly getting louder as time progresses. It is like a gentle whining which occurs in each gear at about 2000rpm.

I'm slowly getting all the pulleys to do the whole lot. I've got a genuine water pump and tensioner.

You're right about the revs dropping back into the rumble zone...I've got too many graphs now to sift through but If I can find the one Ill post it up - showing the valves staying open as long as you don't let it drop below 2400rpm (and it doesn't make a noise unless you do and start the cycle again).

If not already done, you might want to remove the throttle body intake hose to see if the butterfly has been closing. Normally there would be an indication of where it was closing to as carbon builds-up on the manifold side.
