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:
- timing and balance shaft belts. See: Cylinder Block Assembly/Balance Shaft Belt/Service and Repair
Remove balance shaft pulley
Use counterhold 5362.
