What Is It?

Your engines valves open and close under strict timing conditions which allows the fuel mixture into the cylinder for combustion and expels the remaining burnt particles through the exhaust system. For every revolution of your engine your valves open and close once. Consider your engine turning at 5,000 rpm it is understandable your valves will wear.

  • Engine Performing Badly
