(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.).
