18. DISCONNECT HIGH–TENSION CORDS FROM SPARK
PLUGS
19. REMOVE CYLINDER HEAD COVERS
Remove the six nuts, seal washers, cylinder head cover and
gasket. Remove the two cylinder head covers.
20. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with the timing
mark ”0” of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 (IN) are loose and
valve lifters on the on the No.1 (EX) are tight.
If not, turn the crankshaft one revolution (360°) and align the
mark as above.
21. ADJUST VALVE CLEARANCE
(a) Check only those valves indicated in the illustration.
•Using a thickness gauge, measure the clearance between
the valve lifter and camshaft.
•Record out of specification valve clearance measurements.
They will be used later to determine the required
replacement adjusting shim.
Valve clearance (Cold):
Intake
0.13–0.23 mm (0.005–0.009 in.)
Exhaust
0.27–0.37 mm (0.011–0.015 in.)
(b) Turn the crankshaft 2/3 of a revolution (2405), and check only
the valves indicated in the illustration.
Measure the valve clearance.
