Abstract: A valve adjusting and injector preload tool is provided for an internal combustion engine having a valve opening member with a male threaded member operatively and adjustably contacting the valve. The tool includes a first member engagable with the threaded member for rotating the threaded member towards or away from the valve. There is a knob for rotating the first member in a first rotational direction so the male threaded member moves towards the valve and for rotating the first member in a second rotational direction so the male threaded member moves away from the valve. There is a clutch for stopping movement of the first member, as the male threaded member moves towards the valve, when the male threaded member operatively contacts the valve and takes up play between the valve opening member and the valve. There is a scale for measuring a predetermined amount of rotation of the threaded member, as the threaded member is rotated in the second rotational direction away from the valve, after the male threaded member operatively contacts the valve, and thereby setting a specified amount of play between the valve opening member and the valve. The method involves loosening any lock nut on the male threaded member. The male threaded member is rotated in a first rotational direction towards the valve until the male threaded member operatively contacts the valve. The male threaded member is then rotated in the opposite rotational direction for a specified angle of rotation related to the pitch of the male threaded member, such that a specified clearance is set between the threaded member and the valve.
