(b) Check that the timing marks of the camshaft timing

gears are aligned with the timing marks of the
bearing caps as shown in the illustration.
If not, turn the crankshaft 1 complete revolution
(360

°) and align the timing marks above.

14. INSPECT VALVE CLEARANCE

(a) Check the valves indicated in the illustration.

(1) Using a feeler gauge, measure the clearance

between the valve lifter and camshaft.
Valve clearance (Cold):

Intake 0.15 to 0.25 mm (0.006 to 0.010 in.)
Exhaust 0.29 to 0.39 mm (0.011 to 0.015
in.)

(2) Record any out-of-specification valve clearance

measurements. They will be used later to
determine the required replacement valve lifter.

(b) Turn the crankshaft 240

° clockwise, and check the

valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance

between the valve lifter and camshaft.
Valve clearance (Cold):

Intake 0.15 to 0.25 mm (0.006 to 0.010 in.)
Exhaust 0.29 to 0.39 mm (0.011 to 0.015
in.)

(2) Record any out-of-specification valve clearance

measurements. They will be used later to
determine the required replacement valve lifter.

(c) Turn the crankshaft 240

° clockwise, and check the

valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance

between the valve lifter and camshaft.

(2) Valve clearance (Cold):

Intake 0.15 to 0.25 mm (0.006 to 0.010 in.)
Exhaust 0.29 to 0.39 mm (0.011 to 0.015
in.)

Record any out-of-specification valve clearance
measurements. They will be used later to
determine the required replacement valve lifter.

15. ADJUST VALVE CLEARANCE

(a) Set the No. 1 cylinder to TDC/compression.

(1) Turn the crankshaft pulley until its groove and

the "0" timing mark of the timing chain cover
are aligned.

(2) Check that the timing marks of the camshaft

timing gears are aligned with the timing marks
of the bearing caps as shown in the illustration.
If not, turn the crankshaft 1 complete revolution
(360

°) and align the timing marks as above.

(3) Place paint marks on the No. 1 chain links

corresponding to the timing marks of the
camshaft timing gears.

(b) Remove the No. 1 chain tensioner assembly.
(c) Remove the No. 2 camshaft.
(d) Remove the No. 2 chain tensioner assembly.
(e) Remove the camshaft.
(f)

Remove the No. 4 camshaft sub-assembly.

(g) Remove the No. 3 chain tensioner assembly.
(h) Remove the No. 3 camshaft sub-assembly.
(i)

Remove the valve lifters.

(j)

Determine the replacement valve lifter size
according to the following formulas and charts:
(1) Using a micrometer, measure the thickness of

the removed lifter.

(2) Calculate the thickness of a new lifter so that

the valve clearance comes within the specified
value.
T:

Thickness of removed lifter

A:

Measured valve clearance

N:

Thickness of new lifter

Intake:

N = T + (A - 0.20 mm (0.008 in.))

Exhaust:

N = T + (A - 0.34 mm (0.013 in.))

(3) Select a new lifter with a thickness as close as

possible to the calculated value.
HINT:
Lifters 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.).
