Ignition System — Routine Maintenance (Opel Ascona C)

The following operations are performed at the intervals specified in the "Routine Maintenance" section at the beginning of this Manual.

1. Remove and carefully inspect the spark plugs. If the porcelain insulator is damaged, the spark plug should be replaced. Check and adjust the spark gap. Spark plugs are replaced at specified intervals, regardless of their condition.

2. Remove the distributor cap, rotor, top and support plates and drop 1-2 drops of motor oil into the center of the recess on the cam. Lubricate the cam surfaces with Vaseline. Be careful not to apply too much grease, as excess grease may get on the breaker contacts, making it extremely difficult to start the engine.

3. Inspect the contact surfaces of the breaker. If they are pitted or burnt, the gap cannot be adjusted correctly and therefore the contacts must be replaced. Adjust the angle of the closed state of the contacts. The breaker contacts are replaced at specified intervals, regardless of their condition.

4. Inspect the wires and terminals for damage and cracks in the insulation. Check the reliability of the wire fastening. Wires with damaged cores must be replaced. The condition of the insulation of high-voltage wires is of particular importance, since if it is damaged, the voltage can flow to the nearest ground, which will lead to the loss of spark on the spark plug. Check the fastening of the high-voltage wires and see if they rub against the engine, as this can cause premature wear of the insulation.
