(a) If you find magnetic particles:
 - follow the related instructions per (Ref. AMM TASK 79-00-00-281-002) and NDT Manual (section CHIP ANALYSIS).

 (2) If nothing is found:

 - do a check for cracks/leaks at oil tank, lubrication, external oil supply and scavenge lines.
 (a) If there is sign of heavy oil discharge in the center vent tube:

 - replace the engine (Ref. AMM TASK 71-00-00-000-042) and (Ref. AMM TASK 71-00-00-400-042).

 (b) If nothing is found:

 - do a check of the flame arrestor for clogging.
 1 If confirmed:
_
 - clean or replace it (Ref. AMM TASK 72-56-00-000-001) and (Ref. AMM TASK 72-56-00-400-001).
 (3) If nothing is found:

 - remove the TBG/AGB drain plug and do a check for abnormal oil quantity.
 (a) If there is more than one quart:
 - do a check for oil scavenge line blockage or replace the lubrication unit (Ref. AMM TASK 79-21-10-000-004) and (Ref. AMM TASK 79-21-10-400-004).

 (4) If nothing is found:

 - do a borescope inspection of the high pressure compressor stage 1 and 2 to see if they are wet with oil (Ref. AMM TASK 72-31-00-290-002),

 - do an inspection of the fan blades and booster stage 1 at 6 o'clock to see if they are wet with oil,

 - do an inspection of the frame struts and aft side of stage 4 low pressure blades to see if they are wet with oil.

 (a) If there is oil:
 - replace the engine (Ref. AMM TASK 71-00-00-000-042) and (Ref. AMM TASK 71-00-00-400-042).

R  - Replace the XMTR-OIL PRESS (4003EN) (Ref. AMM TASK 79-33-15-000-041) 
R  and (Ref. AMM TASK 79-33-15-400-041). 
R  (1) If the fault continues: 
R  - do a check of the electrical wiring between the ENG2 OIL PRESS XMTR 
R  (4003EN), the SDAC1 and the SDAC2 (Ref. ASM 79-36/01). 
R  (2) If the fault continues: 
R  - replace the SDAC-1 (1WV1) (Ref. AMM TASK 31-55-34-000-001) and 
R  (Ref. AMM TASK 31-55-34-400-001) 
R  (3) If the fault continues: 
R  - replace the SDAC-2 (1WV2) (Ref. AMM TASK 31-55-34-000-001) and 
R  (Ref. AMM TASK 31-55-34-400-001)
