1. Measuring big end axial play
2. Feeler gauge
Connecting Rod Straightness
Align a steel ruler on edge of small end connecting
rod bore. Check if ruler is perfectly aligned with
edge of big end.
ROTARY VALVE
Rotary Valve/Cover Clearance
45° FEELER GAUGE METHOD
Remove intake manifold from rotary valve cover.
Remove rotary valve cover and valve.
Remove O-ring from rotary valve cover.
Reinstall cover WITHOUT its O-ring and torque
screws to 20 N•m (15 lbf•ft).
Insert a feeler gauge blade through cover inlet
ports to verify clearance. At least verify clearance
at two different places in each port.
Feeler gauge blade thickness according to specifi-
cations should fit between rotary valve and cover.

1. 45° feeler gauge
If rotary valve cover clearance is out of specifica-
tions, machine rotary valve cover seating surface
or replace the cover.
SOLDERING WIRE METHOD
Remove rotary valve cover.
Remove O-ring from rotary valve cover.
Use the following type of solder:
– resin core
– diameter : 0.8 mm (.032 in)
– electronic application (available at electronic
stores).
Install 2 soldering wire pieces of 13 mm (1/2 in)
long directly on rotary valve, one above and one
below rotary valve gear. Apply grease to hold sol-
der in position.
Refer to the following illustration for proper posi-
tion of rotary valve and pieces of soldering wire.
