Check valve lashes at valves (1), (2), (5) and (7).
If the rocker arms of No.4 cylinder are off the respective cam
lobes, check valve lashes at valves (3), (4), (6) and (8).

When checking valve clearance, insert thickness gauge
between camshaft and cam-riding face of rocker arm.
7) If valve lash is out of specification, adjust it to specification by
turning adjusting screw after loosening lock nut.
After adjustment, tighten lock nut to specified torque while hold-
ing adjusting screw stationary, and then make sure again that
