NOTE: If an engine turns at speeds below idle, a small
____ quantity of oil leakage can occur. It comes through the carbon seal assembly for the No. 2 bearing. This usually occurs when the engine turns at low speeds for an extended time (when an engine has an extended start/shutdown or when an engine turns freely in the wind). After the engine shutdown, this oil leakage can be on the retention bolts for the variable stator vane at the bottom of the engine. It can also be on the bottom of the nose cone/spinner. This small quantity of oil leakage is permitted.
