Do you have a gauge to measure your oil temperature or are you assuming that because your dash gauge for water (coolant) temperatures read normal your oil temps must be okay? There are a lot of possibilities, but because I am having such problems with my oil cooler I suspect that your oil cooler is going bad. The oil temps are getting high enough for your truck to de-fuel which is your performance problem. Additionally, the lack of coolant flow through your EGR cooler is causing the coolant in the EGR cooler to flash boil and you hear that whistling sound, venting from the degas bottle.
Of course I suspect this only because I am going through the oil cooler replacement for the second time, and I am beginning to eat and sleep oil cooler problems and information so I am quite biased at the current time, added to that that I am not a tech, but it is completely reasonable that this is a possibility for you.
