What happens if valves are not adjusted?
Too much or too little valve clearance can result in poor performance or a rough idle because the engine can’t “breathe” normally and operate at peak efficiency. Too much clearance means the valves will likely clatter and, over the long term, cause damage to the valves, camshaft lobes or rocker arms.
How do you tell if your valves need adjusting?
Your car may have a rough time idling, especially before it has time to warm up. This rough idling is caused by the valve opening late, choking off fuel. Stalling after a cold start is common. In other cases, you may hear a loud rattling noise as the valve knocks against the side of the shaft.
How do you adjust valve clearance?
Hold the post with a spanner while you slacken the locknut, then turn the post anti-clockwise to reduce the clearance and clockwise to increase it. When the gap is correct, hold the post steady while tightening the locknut, then check the clearance. Keep turning the crankshaft until you have checked all the valves.
