4. Check spark plug gap.
Gap: 1.0 - 1.1 mm (0.039 - 0.043 in)
5. Install spark plugs. Reconnect ignition wires according to
numbers indicated on them.
Spark plug:
:20-29N·m (2 - 3 kg-m, 14 - 22 ft-lb)
Checking Ignition Leads
1. Inspect wires for cracks, damage, burned terminals and for
improper fit.
2. Measure the resistance of wires and check for intermittent
breaks.
Resistance:
Cylinder No. Resistance kΩ[at 25°C (77°F)]
1Approximately 3.8
2Approximately 3.5
3Approximately 2.7
4Approximately 2.4
For U.K. (Made by Bougicord)
4.48 - 6.72 kΩ/m (1.365 - 2.048 kΩ/ft) [at 25°C (77°F)]
If it exceeds the limit, replace the ignition wire with a new one.
Checking Positive Crankcase Ventilation
(PCV) System
CHECKING PCV VALVE
With engine running at idle, disconnect ventilation hose from
PCV valve. If valve is working correctly, a hissing noise will be
heard as air passes through it, and a strong vacuum should be
felt immediately when a finger is placed over valve inlet.
