Crankcase ventilation system check (Every 12 000 miles (20 000 km) or 12 months)
1 Inspect the crankcase ventilation system for blockage or damage. A blocked hose can cause a build-up of crankcase pressure, which in turn can cause oil leaks (see illustration).

2 On carburettor model SOHC engines, clean the oil filler cap with paraffin and check that the vent valve is not blocked by pulling it from the oil separator and loosening the hose clip (Section 42).
3 On CVH engines, check that the oil separator and mushroom valve are not blocked, and clean if necessary (see illustration).
