These wires should be inspected at each engine tune-up, and should be replaced if cracked, frayed

or damaged from abrasion. It is important to clean all parts of this secondary system thoroughly

because dirt greatly reduces the available voltage to the spark plugs.

Distributor cap and rotor

Check the distributor cap and rotor for wear, cracks, carbon formation, dirt and corrosion.

Timing delay valve

This valve should be replaced every 30,000 miles. A clogged valve will impair fuel economy. (Not

used on all models).

IV Engine Crankcase Ventilation System

1 Calibrated valve

2 Flame guard

Crankcase ventilation

The engine is provided with positive crankcase ventilation which prevents crankcase gases from

being released into the atmosphere.

Instead, the crankcase gases are admitted to the intake manifold and cylinders.

Cleaning PCV valve

The calibrated positive crankcase ventilation valve should be inspected every 15,000 miles and

cleaned if necessary. Rubber hoses should be checked for damage at the same time. Replace if

necessary.
