Just put my Gen 2 back together after the coolant overhaul and have this odd whistle now. I just changed the intake gaskets to..

Found this vid that sounds exactly like it: https://youtu.be/pzBuc76ONY8

No codes and it runs fine, it sounds like its coming from the egr and didnt start until the engine got warm.
 
Those hard plastic vacuum lines that run to the EGR and the fuel pressure sensor are really, really easy to crack after they have been heat cycled a few years.
You can wave around an unlit (very important that it not be lit) propane torch till the engine idle changes, to locate the leak.
 
I replaced mine with rubber tubing.

My '04 V8 is making the exact same whistle noise. Were you able to pinpoint the cause?
