Check the high pressure oil system for Leaks.
The high pressure oil system operates at high temperature and pressure. Contact with hot oil can
result in burns and scalding. Shut down generator set, and allow system to cool before
performing checks, services, and maintenance. Wear heat resistant gloves and avoid contacting
hot surfaces. Do not allow hot oil or components to contact skin or hands. Failure to comply can
cause injury or death to personnel.
a. Remove the valve cover (WP 0101) and inspect the high pressure oil system
for oil leaks.
(1) While the engine is being cranked, inspect the area around the injector
bores for any signs of oil leakage.
(2) Inspect the spill ports of the injector for excessive oil. All six injectors
should spill the same amount of oil.
b. If no leaks are apparent, the high pressure oil system is not leaking. If the
diagnostic codes are still present, there may be an engine problem.
If a leak in the high pressure oil system has been found, replace the o-ring on
the injector or replace the damaged injector (WP 0114). Verify that the repair
has resolved the problem.
d. If the problem is not resolved, replace the engine.
164-E-02 Injection Actuation Pressure signal erratic, intermittent, or incorrect.
If diagnostic code 164-E-02 is present, refer to Injection Actuation Pressure
After diagnostic code 164-E-02 has been corrected, return to the Injection
Actuation Pressure Test if necessary.
