Valve Float, Glossary and Terms, Automotive, Motorcycle, Boat Dealers
List of United States Automotive, Motorcycle, Boat, Dealers, Service Stations
A high-rrpm engine condition in which the valve lifters lose contact with the cam lobes because the valve springs are not strong enough to overcome the momentum of the various valvetrain components. The onset of valve float prevents higher-rpm operation. Extended periods of valve float will damage the valvetrain.
