Oil feed line construction
overview:
1. Stainless steel flexible section. This is the new design and
should not be replaced.
2. Black rubber flexible section. This line should be replaced.
1. Remove and install the engine acoustic cover as per Repair Instructions 11 12 070 “Removing &
installing/replacing the acoustic cover”
2. Check the exhaust turbocharger oil feed line on bank 1.
If the flexible section of the feed line is made of braided
stainless steel (see arrows) then take no further action. Do
not replace the line.
If the flexible section is black rubber then the oil feed line will
need to be replaced.
3. Check the exhaust turbocharger oil feed line on bank 2.
If the flexible section of the feed line is made of braided
stainless steel (see arrows) then take no further action. Do
not replace the line.
If the flexible section is black rubber then the oil feed line will
need to be replaced.
4. If the oil feed lines were actively leaking oil.
Check the engine block (V-space) for engine oil residue and
clean as needed.
If there is leakage, the exhaust system, both exhaust
turbochargers, the lower heat shield, the complete exhaust
manifold and the oil-to-coolant heat exchanger needs to be
removed to clean this area.
