SUBJECT:
DD Platform Heavy Duty Metal in the Oil and Oil Filter
ISSUE
Some engine component failures can cause metallic debris to circulate throughout the engine
lubrication system. Although the oil filter will capture most of this debris, some debris may enter
the clean side of the lubrication system during oil filter bypass.
Detroit has created a lubrication system cleaning and flushing procedure to address this
problem. In addition, there are guidelines listed below related to the replacement of oil lubricated
engine components. These components: oil coolant module, turbocharger, air compressor, gear
train, camshaft housing, camshafts, and rocker arms, are flushed when following this process.
REQUIRED ACTION
PERSONAL INJURY
To avoid injury from hot surfaces, wear protective gloves, or allow engine to cool before
removing any component.
PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level
surface, parking brake is set, and the wheels are blocked.

FIRE
To avoid injury from fire, keep open flames, sparks, electrical resistance heating elements, or
other potential ignition sources away when draining lubrication oil. Do not smoke when
draining lubricating oil
1. Verify metallic debris is present in the oil pan and in the pleats of the oil filter.
2. Clean and flush the engine lubrication system. Refer to the section; “Flushing the Engine
Lubrication System” in the appropriate Workshop Manual for the engine.
3. Replace the following components, in addition to the components listed in the flushing
procedure:
 Oil suction manifold
 Oil pump
 The Primary Failed Part (PFP) that led to the metal in the oil
4. Do not replace the following components unless damage is found during the time of this
repair. Use the appropriate inspection sections in the workshop manual to determine if
these components are damaged.
 Oil coolant module
 Turbocharger
 Air compressor
 Gear train components
 Camshaft housing, camshafts, and rocker arms
