On most , engines the procedure is the same, rotate the engine by hand until either the intake rocker arm is loose or the exhaust rocker arm is loose. Then get feeler gauges with the correct clearance marked on them,, and put it between the valve spring and the tapper then loosen the lock nut, screw down the stud until you get a little resistance moving the feeler gauge back and forth, and while holding the little stud that taps the valve, tighten the adjuster nut. Repeat for exhaust valve .
