10. INSPECT VALVE CLEARANCE
HINT:
Inspect and adjust the valve clearance when the engine is cold.
(a) Check only the valve indicated.
(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 determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake 0.19 – 0.29 mm (0.0075 – 0.0114 in.)
Exhaust 0.30 – 0.40 mm (0.0118 – 0.0157 in.)
(b) Turn the crankshaft clockwise 1 revolution (360) and set
No.4 cylinder to TDC/compression.
(c) Check only the valve indicated.
(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 determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake 0.19 – 0.29 mm (0.0075 – 0.0114 in.)
Exhaust 0.30 – 0.40 mm (0.0118 – 0.0157 in.)
11. ADJUST VALVE CLEARANCE
NOTICE:
Be sure not to turn the crankshaft without the chain ten-
sioner.
(a) Turn the crankshaft clockwise 1 revolution (360) and set
the No.1 cylinder to the TDC/compression.
(b) Place matchmarks on the timing chain and camshaft tim-
ing gear.
(c) Remove the 2 bolts and chain tensioner.
(d) Fix the camshaft with a spanner and so on, then loosen
the camshaft timing gear set bolt.
NOTICE:
Be careful not to damage the valve lifter.
