Troubleshooting Test Steps Values Results
1. Check the Engine Oil Level
Oil Level
Result: The engine oil level is OK.
Proceed to Test Step 2.
Result: The engine oil level is high.
Repair: Troubleshoot and repair the cause of the incorrect oil level.
If the problem is not resolved, proceed to Test Step 2.
2. Check for Plugged CCV System or Clogged Filters
A plugged CCV system or clogged filter will cause excessive crankcase pressure.
Plugged Crankcase Breather
Result: The crankcase breathers are NOT OK.
Repair: Replace the fumes disposal filter according to the Operation and Maintenance Manual, "Engine Crankcase Breather - Clean".
Result: The crankcase breathers are OK.
Proceed to Test Step 3.
3. Check for a Faulty Pressure Sensor
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Turn the keyswitch to the ON position. Do not start the engine.
C. Remove the oil filler cap.
D. Monitor the crankcase pressure and the atmospheric pressure in Cat ET.
Crankcase Pressure Sensor
Result: The crankcase pressure is within 3.5 kPa (0.5 psi) of the atmospheric pressure.
Proceed to Test Step 4.
Result: The crankcase pressure is not within 3.5 kPa (0.5 psi) of the atmospheric pressure.
Repair: Replace the crankcase pressure sensor.
If the problem is not resolved, proceed to Test Step 4.
4. Internal Engine Problem
Damaged pistons or rings can cause too much pressure in the crankcase. This condition will cause the engine to run rough. There will be more than the normal quantity of fumes (blowby) entering the crankcase breathers. The crankcase breathers can then more quickly become restricted, causing oil leakage at gaskets and seals that would not normally have leakage. Blowby can also be caused by worn valve guides or by a failed turbocharger seal.
A. To determine whether the piston rings leak, measure the crankcase blowby.
B. Perform the Compression Test using Cat ET. Refer to Testing and Adjusting, "Compression - Test" for additional information.
Damaged or Worn Engine Parts
Result: There are worn or damaged engine parts.
Repair: Repair or replace the worn or damaged parts.
Result: At least one cylinder has been identified as having low compression.
Repair: Identify the cause of the low compression. Possible causes of low compression include the following:
- Faulty piston
- Faulty piston rings
- Worn cylinder bores
- Worn valves
- Faulty cylinder head gasket
- Damaged cylinder head
Perform the necessary repairs.
Result: The compression for each cylinder is OK.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
