ABSTRACT:
A quick release bolt that replaces all the valve cover bolts presently in use in vehicles. To remove a vehicle's valve cover, the mechanic engages the quick release lever and the bolt simply lifts off. Stud bolts are installed in the engine head to hold the quick release bolts. Once the quick release bolts are removed, the valve cover can be removed by lifting it over the stud bolts. The valve adjustments can then be made and the valve cover and gasket can the be replaced. The bolts are then quickly snapped into place over the stud bolts and the valve cover is again secured to the engine. Although this device was developed for racing engines, it can be used in any application that utilizes bolts to secure one object to another.
