Camshaft Oil Seal: Service and Repair

NOTE: Special Tools Required: 5284, 5025, 5034.

PRELIMINARY CHECKS: 

1. Check that flame guard is not blocked. A blocked flame guard prevents crankcase ventilation from operating properly. Crankcase pressure will be

too high.

NOTE: Flame guard should not be installed on turbo engines.

2. Symptoms of a blocked flame guard are:

-

oil dipstick pops up of pipe.

-

oil leaks from oil seals in cylinder block. The oil seals need not always be replaced if they leak due to a blocked flame guard. Clean flame
guard and engine and recheck seals for leakage

-

engine knocks.

REMOVAL PROCEDURE:
Disconnect/Remove:
 

1. Disconnect battery ground cable.
2. Remove cooling fan.
3. Remove clamp for preheating hose below fan shroud (optional).
4. Remove fan shroud.
