Arm Pivot Studs.
2. Apply grease to the contact surfaces of the
rocker arms and adjusting nuts and install them
onto the pivot studs.
NOTE: If being reused, push rods should always be
installed in their original position.
3. Note the mark or tag identifying the push rod as
either intake or exhaust. Apply grease to the ends
of the push rods. Insert the push rods into the
push rod bores and seat the lower end into the
dimpled recess of the cam levers. It may be
necessary to lift or shift the lower end of the push
rod slightly, and "feel" that the rod seats into the
recess. Once seated, hold it in place as you
position the rocker arm. The push rod must stay
in the recess while the rocker arms are
positioned and adjusted. See Figure 10-38.

4. With the engine at TDC of the compression
stroke, insert a 0.076 mm (0.003 in.) flat feeler
gauge between one of the valve stems and the
rocker arm. Tighten the adjustment nut with a
wrench until a slight "drag" is felt on the feeler
gauge. Hold the nut in that position and torque the
set screw (T15 Torx drive) to 5.5 N·m (50 in. lb.).
Perform the adjustment procedure on the other
valve. Proper valve clearance is 0.076/0.127 mm
(0.003/0.005 in.). See Figures 10-39 and 10-40.

Install Valve Cover

1. Make sure the sealing surfaces of the valve
cover and cylinder head are clean, and free of
any nicks or burrs.
2. Install a new valve cover gasket, followed by the
valve cover. Position any brackets that mount on
the valve cover and start the seven mounting
screws.
