12. INSPECT VALVE CLEARANCE
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 the 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.

13.ADJUST VALVE CLEARANCE
NOTICE:
Be sure not to turn the crankshaft without the chain ten-
sioner.
(a)Set the No. 1 cylinder to TDC/compression. (See page 14±240)
(b)Remove the chain tensioner. (See page 14±240)
(c)Remove the camshafts. (See page 14±240)
(d) Tie the timing chain with a string.
NOTICE:
Be careful not to drop anything inside the timing chain cov-
er.
(e) Remove the valve lifters.
(f) Using a micrometer, measure the thickness of the re-
moved lifter.
(g) Calculate the thickness of a new lifter so that the valve clearance comes within the specified valve.

HINT:
Select a new lifter with a thickness as close as possible
to the calculated valves.
Lifter are available in 35 sizes in increments of 0.020 mm
(0.0008 in.), from 5.060 mm (0.1992 in.) to 5.740 mm
(0.2260 in.).
Identification number inside the valve lifter shows the val-
ue of the 2 decimal places. (The illustration shows 5.380
