- The Aft sump (oil No leak allowed Replace the oil inlet
 inlet cover O-ring)  cover O-ring (Ref. TASK 72-56-00-000-002) (Ref. TASK 72-56-00-400-002).
 NOTE : Oil puddling in the exhaust/aft sump area/centerbody must be
____ considered as normal as long as the oil consumption rate is within
 serviceable limits.

 2. The fuel source
 - The fuel manifold  No leaks allowed  Perform a leak check at
 shroud  the manifold assembly (Ref. TASK 73-11-40-790-002).
 - Fuel pump at the AGB drive pad  180 ml/hr (3 cc/min) (60 drops/min) (up to 90 drops/min allowed for 25 cycles)  Replace the fuel pump(Ref. TASK 73-11-10-000-003) and (Ref. TASK 73-11-10-400-003).

 NOTE : The heat exchanger, VSV actuator(s), VBV fuel gear motor, HPTCC
____ valve, BSV, LPTCC valve, RACC valve, HMU and the fuel distribution block share the same fuel drain line at the drain mast manifold. There may be more than one unit leaking. Isolate which unit is leaking by disconnecting the drain tubes at each component.
 - Heat exchanger  180 ml/hr (3 cc/min) (60 drops/min) (up to 90 drops/min allowed for 25 cycles)  Replace the main oil/fuelheat exchanger (Ref. TASK79-21-20-000-002) and(Ref. TASK 79-21-20-400-002).
 - VSV actuator(s) (LH or RH)  180 ml/hr (3 cc/min) (60 drops/min) (up to 90 drops/min allowed for 25 cycles)  Replace the VSVactuator(s) (Ref. TASK 75-32-10-000-002) and(Ref. TASK 75-32-10-400-002).
