High-pressure fuel pump
Cracked cylinder headRecommended Actions
Complete the procedure in the order in which the steps are listed.
Table 1
Troubleshooting Test Steps     Values     Results    
1. Leaking Seals
A. Remove the injector from the affected cylinder and visually inspect the injector O-ring seals for damage.
If leakage is found and the O-rings are in good repair, there may be a problem with the injector. Replace the injector. Ensure that the new trim files are installed. Refer to Troubleshooting, "Injector Trim File - Install" for details. Use Caterpillar Electronic Technician (ET) to perform a "Fuel System Verification Test". Refer to Troubleshooting, "Injector Solenoid - Test" for details.
If the leakage is not located, add the appropriate dye to the fuel tanks. Run the engine at high idle for several minutes. Shut down the engine and remove the valve covers. Use a black light to check for traces of dye around each injector.
   
O-ring Seal    
Result: The injector O-ring seal is damaged.
Repair: Replace the damaged seals. Install the injector onto the engine and confirm that the repair has resolved the problem.
Result: The injector O-ring seal is not damaged.
Proceed to Test Step 2.    
2. Fuel Injector Tip
A. Use Cat ET to perform the "Cylinder Cutout Test" in order to identify any cylinders that may be overfueled.
B. A fuel injector tip that is broken or fractured is a possible cause of a cylinder that is being overfueled. If a cylinder is identified by the test, Remove the injector and check the injector tip for damage. Check the fuel injector tip for cracks or breakage.
   
Injector Tip    
Result: The fuel injector tip is damaged.
Repair: Replace the suspect injector.
Result: The fuel injector tip is not damaged.
Proceed to Test Step 3.
   
3. Fuel Transfer Pump Seal
A. Check for fuel leakage around the shaft seal for the fuel transfer pump. Ensure that the weep hole is not plugged.
   
Pump Seal    
Result: There is fuel leakage around the shaft seal.
Repair: Replace the fuel transfer pump.
Result There is not fuel leakage around the shaft seal.
Proceed to Test Step 4.
   
4. High-pressure fuel pump
A. Remove the plug from the bottom of the high-pressure fuel pump. Remove the plug from the bottom of the fuel pump adapter. Expect that a small amount of engine oil will drain from the openings.
B. Use the manual override for the fuel priming pump to run the pump in order to pressurize the fuel system. Allow the pump to run for at least 5 minutes while you monitor the drain holes in the pump and the adapter for leakage.
   
Defective Pump    
Result A leak is detected.
Repair: Replace the high-pressure fuel pump.
Result No leak is detected.
Proceed to Test Step 5.
   
5. Cracked Cylinder Head
A. Look for signs of damage to the internal passages for the fuel supply to the injectors in the cylinder head. Check for pin hole leaks. Refer to Disassembly and Assembly.
   
Cracked Head    
Result The internal passages for the fuel supply to the injectors are damaged.
Repair: Repair or replace the cylinder head.
