Here it is from one of my FSM's (complete with crappy japanese translation ): (Note that you do this to the valves when they are in the slack position, with the cylinder you are adjusting at TDC on the compression stroke.... [and you don't need the silly tool - 6" crescent wrench works just fine]) a. Raise up the bend of the lock washer, loosen the lock nut, and then turn the valve rocker screw clockwise by approx. four (4) turns using Valve Clearance Adjuster 498767000. b. Leave it with the valves opened for approx 15 minutes. c. Unscrew the valve rocker screw gradually. Then, the rocker arm stops moving due to the closing of the valve. This condition is called "Zero Point". d. Moreover, unscrew the valve rocker screw counterclockwise by another 1.5 turns. e. Tighten the lock nut and bend the lock washer.
