HIGH OIL CONSUMPTION - Continued
MALFUNCTION
Piston pin retainer loose.
CORRECTIVE ACTION
1.
To determine if uncontrolled oil is in air box, remove air box covers (TM 55-1925-205-10). Run
engine at idle speed. Check for excess oil slobbering from cylinder liner ports. Inspect all
cylinders as more than one may be slobbering. Rebuild affected pistons and liners. Contact
Maintenance Supervisor.
2.
Install air box covers (TM 55-1925-205-10).
3.
Perform operational check of diesel engine (TM 55-1925-205-10).
MALFUNCTION
Worn oil control rings broken, scored or improperly installed.
CORRECTIVE ACTION
1.
Rebuild pistons and liners. Contact Maintenance Supervisor.
2.

MALFUNCTION
Excessive oil in air box.
CORRECTIVE ACTION
1.
To determine if there is excessive oil in air box, remove air box covers (one at a time)
(TM 55-1925-205-10). Run engine at idle speed. Check for excess oil slobbering from cylinder
liner ports. Inspect all cylinders as more than one may be slobbering. Rebuild pistons and liners.
Contact Maintenance Supervisor.
2.
Install air box covers (TM 55-1925-205-10).
3.
Perform operational check of diesel engine (TM 55-1925-205-10).
4.
Check for leakage from blower oil seals. Remove piping from inlet housing and from blower.
Operate engine at idle. Inspect blower end plates for oil leakage. Use a flashlight to illuminate if
necessary. If oil leakage is present, repair the blower. Contact Maintenance Supervisor.
5.
Perform operational check of diesel engine (TM 55-1925-205-10).
6.
Check for leaking oil seal on turbocharger and replace turbocharger as necessary (WP 0114).
7.
Perform operational check of diesel engine (TM 55-1925-205-10).
8.
To confirm a leaking oil seal, check for oil residue on compressor and on turbine sides of the
turbocharger. Remove compressor housing, if applicable, and inspect the backplate. If the
surface is wet with oil, seal is leaking. Replace turbocharger (WP 0114).
9.
Perform operational check of diesel engine (TM 55-1925-205-10).
