How To Adjust Air Cooled VW Valves

Step by step instructions on how to adjust the valves in your air cooled VW engine.

Keeping your valves adjusted will help your air cooled engine to run smoother and more efficient. Improper valve clearances are one of the primary core causes of mechanical and efficiency problems in air cooled engines. Due to the nature of the air cooled engine keeping your valves adjusted will have a major impact on your classic Volkswagens life and performance.

If the valve clearances are too small the valves will remain open too long which will cause them to over heat. If clearances are too large the opposite will happen, the valves will stay closed too long and will interfere with the intake of fuel and exhaust of burned fuel. Either way, if your valves aren’t adjusted correctly your air cooled Volkswagen will not run smoothly.  Read on to learn how to adjust your own valves.
