Please do your 2 minute cool-downs. If not, coke will form in the turbine rotor lubricating oil passages, and eventually starve the bearings of oil. It's been a while but I think on the 100-hr. inspections we would remove the oil sump at the bottom of the turbine rotor (it looks like a silver box about the size of a cigarette pack), and using a mirror look up inside the oil passage for coke.
We could always tell when the cool-downs were not done. The coke forms easily and the diameter of the oil passage gets smaller and smaller (much like a clogged artery, I suppose).
Will the engine quit? If not caught and cleaned on the 100-hr. inspection, then coke builds and could lead to bearing failure. Chip lights are meant to warn you, but by then it is too late to prevent the expensive repair bill.
