Loud whistling noise from engine

Happy Easter!

I have a 2010 LR2 Sport(3.2L I6), with approx 155,000 km, it has developed an extremely loud whistling/squealing noise from under the hood, the noise is not there at initial start up when cold and starts after about 5-10 mins of run time, it does not change with speed and disappears when I pull the engine oil dipstick or remove the oil fill cap (excessive suction), it also disappears with the engine under load, I assume it is a very large vacuum leak but after taking the skid plate and air box off, and spraying around I can not find the source.

Is there a PCV system schematic, or a vacuum hose schematic anywhere for this thing?

Any thoughts, suggestions, or ideas would be very much appreciated.

Thanks!

Doug
