APU
Runs at a much higher rpm with less mx and many more “hours” before overhaul. NK has found that the seals leak on the APU and the oil leaks and atomizes into the bleed system. See the guys post a few pages back where everything was fine until he started the APU.
It's not that simple, I'll try and give a better answer when I have time. I still believe the IAE is the biggest problem.
