Valve Lash Adjustment

I do it the slow way but its always worked for me. first after you have the cover off look at the first rocker and either using the starter to bump the motor or turn the crank pulley by hand watch for the rocker to come all the way up, telling you the valve is all the way closed and the lifter is on the back side of the cam lobe. once that is done loosen the set screw on the rocker and back it off all the way so the rocker is loose. now you need to take adjuster on the rocker and turn it until you feel it stop against the pushrod and don't tighten it, stop as soon as you feel tension. at this point you have "zero lash". that basically means the pushrod has no more play up and down. the last step is to then turn the adjuster down another half to a full turn. most adjusters are 24 threads per inch so one turn equals .040. lock that adjustment down and move on down the line.
