    Instructions for use:

    If using with the head on the block, cylinders need to be pressurized to 100PSI to prevent the valve from falling into the cylinder. If using with the head out of the engine compartment, put something bellow the valve to keep it pressed upward.

    Align the holes on the tool with the one the head, and place the shorter bolts and washers to secure the tool.

    Place the retainer cap on top of the retainer, lubricate the long bolt with provided grease and start turning the long bolt clockwise with the help of a wrench (14mm) to apply pressure to the retainer cap and compress the valve spring until the keepers are completely visible and can come out.

    Using the magnetized end of the screw driver remove the keepers.

    To reinstall the valve assembly, place the valve (if removed for some reason), valve seals, valve spring, and retainer; compress the assembly using the same steps as above.

    Place a small amount of the provided grease on the flat tip of the screw driver and place a keeper over it, the grease will hold the keeper in place and allow you to place the keepers easily. 

    Once keepers are in place, start turning the bolt counterclockwise to relieve the pressure of the valve spring.
