ABSTRACT:
A device or tool for facilitating removal of overhead automotive valves for inspection and repair of the stem and sleeves comprising a knob operated toggle mechanism which is inserted in the opening left after removal of a spark plug. The toggle mechanism holds the valve tight against the seat on the cylinder head interior permitting removal of the overhead spring and accompanying parts. After completion, the spring and retainer are replaced, the tool removed and the spark plug replaced. This emiminates the use of compressed air for this purpose as was previously the case.
