I'm a relative newbie when it comes to engine rebuilding, the physics, mechanics, etc, but I'm fascinated by it all and have been reading up on how it all works... I've done my share of valve adjustments, but the thought came to mind--why do we adjust valves? Is it a combination of heat and wear that causes them to need adjusting? Does spring fatigue have something to do with it?? |

Accordint to Auto Atlanta:
"Proper valve adjustment is critical to proper engine operation. Since the 914 engine is air cooled, it operates in a much broader temperature range than a water cooled car, resulting in more extreme expansion and contraction. This movement necessitates periodic valve adjustment." Eric Read |
