HINT:
Inspect and adjust the valve clearance when the engine is cold.
(a) Check only the valve 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 determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake 0.19 to 0.29 mm (0.0075 to 0.0114 in.)
Exhaust 0.30 to 0.40 mm (0.0118 to 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 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 determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake 0.19 to 0.29 mm (0.0075 to 0.0114 in.)
Exhaust 0.30 to 0.40 mm (0.0118 to 0.0157 in.)
