7/13


Remove the valve cover and inspect the high pressure oil system for excessive oil leaks or discharge.A.

Look at the injector bores for any signs of oil leakage while the engine is being cranked. Inspect the spill ports on the injectors for aexcessive discharge of oil. All six injectors should discharge the same amount of oil. Excessive leakage or discharge can cause issuwith the system pressure. Record the following data:

B.

________ Any injectors with excessive leakage or discharge

Turn the key to the "OFF" position. A electrical shock hazard is present if the key is not turned to the "OFF" position.C.

Not OK - If the unit injector hydraulic pump has already been replaced in a previous test, stop and consult your local technicalcommunicator for assistance.

Test Step 10. Check the Low Pressure Fuel and Oil System Pressures

Extended oil drain intervals may cause elevated levels of soot in the engine oil. The elevated levels of soot may also deplete the additivepackage of the oil. This can affect the operation of the high pressure oil system.

Note: Refer to the engine's Operation and Maintenance Manual for the recommended engine oil change interval and refill capacities.

Escaping fluid under pressure, even a pinhole size leak, can penetrate body tissue,causing serious injury, and possible death. If fluid is injected into your skin, it must be

treated immediately by a doctor familiar with this type of injury.

Always use a board or cardboard when checking for a leak.

Start the engine.A.

Observe the status for "Fuel Pressure" and "Engine Oil Pressure" on Cat ET while the engine is running. Record the following dataB.

________ Observed fuel pressure from Cat ET

________ Observed engine oil pressure from Cat ET

________ Drain interval

________ Miles or Kilometers since the last oil change

Expected Result:

The customer has not exceeded the suggested oil change interval.

OK - The customer has not exceeded the suggested oil change interval.




9/13

Repair: Refer to Systems Operation, Testing and Adjusting, "Fuel System Pressure - Test" and Systems Operation/Testing andAdjusting, "Engine Oil Pressure - Test" in order to verify that the observed fuel pressure and engine oil pressures are acceptable.If -1 diagnostic code is active or if a 94-1 diagnostic code is logged, a problem in the fuel supply system has occurred. Refer to SysteOperation, Testing and Adjusting, "Fuel System Pressure - Test". Make necessary repairs. Verify that the repair eliminates the

problem.


Not OK - The customer has exceeded the suggested oil change interval.

Repair: If the customer has exceeded the suggested oil change interval, ask the customer to authorize an oil change with a new filtOil changes are not covered by the warranty. After the engine oil and the oil filter have been changed, operate the engine until norm

operating temperature has been reached. Operate the engine at 1200 to 1500 rpm for 15 minutes. This will purge any trapped air ordebris that is in the system.

If the problem still exists, or if the problem reoccurs in a short period of time, repeat Test Step 10.
