6. DISCONNECT VENTILATION HOSE NO.2
(a) Disconnect the ventilation hose from the cylinder head
cover.
7. REMOVE CYLINDER HEAD COVER SUB±ASSY
(a) Remove the 9 bolts, 2 seal washers, 2 nuts, 3 clamp
brackets and cylinder head cover.
8. REMOVE ENGINE UNDER COVER SUB±ASSY NO.1
9. REMOVE ENGINE UNDER COVER RH
10. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align the timing notch with
timing mark º0º of the timing chain cover.
(b) Check that the point marks of the camshaft timing sprock-
et and VVT timing sprocket are in straight line on the tim-
ing chain cover surface as shown in the illustration.
HINT:
If not, turn the crankshaft 1 revolution (360
) and align the
marks as above.
11. INSPECT VALVE CLEARANCE
(a) Check the valves 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 valve lifter.
Valve clearance (Cold):
Intake 0.15 to 0.25 mm (0.0059 to 0.0098 in.)
Exhaust 0.25 to 0.35 mm (0.0098 to 0.0138 in.)

inder to TDC/compression.
(c) Check the valves 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 valve lifter.
Valve clearance (Cold):

12. REMOVE FAN AND GENERATOR V BELT
(a) Turn the V±ribbed belt tensioner clockwise slowly and
loosen it. Then, remove the fan and generator V belt and
put back the V±ribbed belt tensioner carefully.
13. REMOVE ENGINE MOUNTING INSULATOR
SUB±ASSY RH
(a) Place a wooden block on a jack underneath the engine.
Remove the 4 bolts and 2 nuts and detach the engine
mounting insulator RH.

14. REMOVE V±RIBBED BELT TENSIONER ASSY
(a) Remove the bolt and nut, then remove the V±ribbed belt
tensioner.
HINT:
Jack up and down to remove the bolt.
15. ADJUST VALVE CLEARANCE
NOTICE:
Be sure not to revolve the crankshaft without the chain ten-
sioner.
(a) Set the No. 1 cylinder to the TDC/compression.
(b) Place match marks on the 2 camshaft sprockets and paint
marks on the timing chain.
(c) Remove the 2 nuts and the chain tensioner.
(d) Hold the camshaft with a wrench, loosen the camshaft
timing gear set bolt.
NOTICE:
Be careful not to damage the valve lifter.

(e) Using several steps, loosen the camshaft bearing cap
bolts on the No. 2 camshaft in the sequence shown in the
illustration and remove the bearing caps.
(f) Remove the camshaft timing gear as shown in the illustra-
tion.
(g) Using several steps, loosen the camshaft bearing cap
bolts on the camshaft in the sequence shown in the il-
lustration and remove the bearing caps.

Example (Intake):
Measure intake valve clearance = 0.40 mm (0.0158 in.)
0.40 mm (0.0158 in.) ± 0.20 mm (0.0079 in.) = 0.20 mm (0.0079 in.)
(Measured ± Specification = Excess clearance)
Used lifter measurement = 5.250 mm (0.2067 in.)
0.20 mm (0.0079 in.) + 5.250 mm (0.2067 in.) = 5.450 mm (0.2146 in.)
(Excess clearance + Used lifter = Ideal new lifter)
Closest new lifter = 5.460 mm (0.2150 in.)
Select No. 46 lifter

(j) Remove the valve lifters.
(k) Using a micrometer, measure the thickness of the re-
moved lifter.
(l) Calculate the thickness of a new lifter so that the valve
clearance comes within the specified value.
AThickness of new lifter
BThickness of used lifter
CMeasured valve clearance
Valve clearance:
Intake A = B + (C ± 0.20 mm (0.0079 in.))
Exhaust A = B + (C ± 0.30 mm (0.0118 in.))
HINT:

Select a new lifter with a thickness as close as possible
to the calculated values.

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.).
