Camshaft Oil Seal: Service and Repair
Camshaft Seals, Replacement
Special tools: 5025, 5199
On later versions of engines, seals may be replaced without removing transmission mounting plate.
Check that flame trap is not blocked
Flame trap blockage restricts crankcase ventilation and increases crankcase pressure.
Symptoms of flame trap blockage:
- Oil dipstick tends to lift in tube.
- Oil leakage from cylinder block seals.
- Seals do not always require renewal if leakage is due to this cause. Overhaul flame trap, clean engine and reinspect for seal leakage.
- Engine knocks.
Remove:
- battery earth lead
- alternator drive belt
- radiator fan and pulley
