Inspect and adjust the valve clearance when the engine is cold.
1. REMOVE INTAKE AIR PIPE
2. REMOVE INTAKE PIPE (See pa ge EM -- 44)
3. REMOVE CYLINDER HEAD COVER
(See page EM -- 44)

(a) Turn the crankshaft pulley clockwise, and align its groove
with the timing pointer.
(b) Check that the valve lifters on the No.4 cylinder are loose
and valve lifters on the No.1 cylinder are tight.
If not, turn the crankshaft one revolution (360˚) and align the
mark as above.
5 . CHE CK VALV E CLE ARANCE
(a) Check only the valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record the out -- of--specification valve clearance
measurements. They will be used later to deter-
mine the required replacement adjusting shim.
Valve c learance (Cold):
Intake 0.20 -- 0.30 mm (0.008 -- 0.012 in.)
Exhaust 0.25 -- 0.35 mm (0.010 -- 0.014 in.)
(b) Turn the crankshaft pulley one revolution (360˚) and align
the mark as above (See procedure step 4).
(c) Check only the valves indicated as shown. Measure the
valve clearance. (See procedure in step (a))
6 . ADJ US T VALV E CLE ARANCE
(a) Remove the adjusting shim.
(1) Turn the crankshaft to position the cam lob of the
camshaft on the adjusting valve upward.
(2) Using SST, press down the valve lifter.
