ok if the oil got that hot wich would have to be higher then 350*f. very easy theroy to test.... remove the oil filter and see if the stand pipe is still there. it will melt at 350*.
if oyu have a broken y-pipe you have an exhaust leak that is ever present look for soot on the fire wall.

I hesitate to even offer an opinion because you guys know so much more about this than I. But defueling due to overheating sure seems like it matches his symptoms. That overheating could be the oil or coolant. I'm thinking oil due to a clogged cooler, and the boiling sound is in the EGR cooler.
It's okay to laugh at my stupid ideas, I won't be offended.

If you guys can pm me your e-mail address I will send you a pic of the brown stain. I don't think the FTE e-mail feature allows pics to be sent and I aint no computer geek, FOR SURE.

The stain on the turbo is normal. It may be a little bit of CCV oil seeping from the end of the hose--bleed threw (through?). As for the whistle--what all, if anything, did ford do or replace or can you point towards an old thread? Did they ever smoke test the system? Ever consider an intake gasket or EGR cooler to intake gasket? I can only think of so many things that would whistle--y-pipe system, intake gaskets , head gaskets (degas bottle cap whistle), belt and associated parts (constant or rpm related). Also, is the whistle a constant pitch or does it vary?

Whistle is constant pitch. Seems to come on when rpms and fan clutch are in sync. I am starting with Y pipe (part of egr delete). I will also go through and check all of the exhaust manifold bolts that I can reach. If this does not stop the annoying whistle, I am probably going to eventually try changing the belt and idler pully. I have also been told that a clutch fan from a snow plow package is a good improvement on the 6.0, especially for towing, but that will probably have to wait until I have more funds. I would think that if the whistle is heat related, a more efficient clutch fan might help keep it cool...
The most concerning issue right now is the boost problem. We'll see if the egr delete fixes that one. If not, I will be combing these pages to see if there was something I missed that someone may have suggested and I missed. Knowing that the brown staining is normal is a relief to me as I really don't want to consider a new turbo at this point. I'm just about out of money once the egr delete is accomplished.
Thanks for all the help. If you all think of anything else, please send me your thoughts.
Thanks, T

Here is the thread I started a long time ago on the whistle. It appears that I'm not the only one...

Based on my experience with E350 ambulances here in Switzerland, this is a common point of concern from medics, which only occurs during hot days (about 100°F these days and going uphills, not uncommon around here). Engine heats and fan takes over, resulting in a very high whine and big loss of power. I am not sure if this answers this specific question but your description goes completely along those of the medics. We've never had technical issues resulting from this
