(7) Remove fuel pipe protector LH.

(8) Disconnect fuel injector connectors. (A)
(9) Disconnect front oxygen (A/F) sensor con-
nector. (B)

(10)Remove ignition coils. <Ref. to IG(H6DO)-7,
REMOVAL, Ignition Coil and Ignitor Assembly.> 
(11)Remove rocker cover LH. <Ref. to
ME(H6DO)-50, REMOVAL, Camshaft.>  

9) Using the ST, turn the crankshaft clockwise. Ad-
just the camshaft position so that the cam lobe is
perpendicular to the shim as shown in the figure.

10) Measure intake valve and exhaust valve clear-
ances by using thickness gauge (A).

NOTE:
Insert the thickness gauge in as horizontal a direc-
tion as possible with respect to the shim.

NOTE:
If the measured value is not within specification,
take notes of the value in order to adjust the valve
clearance later on.

12) Further turn crankshaft pulley clockwise. Using
the same procedure described previously, then
measure valve clearances again.
13) After inspection, install the related parts in the
reverse order of removal.

B: ADJUSTMENT

NOTE:
Adjustment of valve clearance should be per-
formed while engine is cold.
1) Measure all valve clearances. <Ref. to
ME(H6DO)-22, INSPECTION, Valve Clearance.>  

NOTE:
Record each valve clearance after it has been
measured.

2) Remove shim from valve lifter.

(1) Prepare the ST.

(2) Rotate the notch of the valve lifter outward
by 45

°

.

(3) Adjust SHIM REPLACER notch to valve lift-
er and set it.

NOTE:
When setting, be careful SHIM REPLACER edge
does not touch shim.

(4) Tighten bolt (A) and install it to the cylinder
head.
(5) Tighten bolt (B) and insert the valve lifter.

(6) Insert tweezers into the notch of the valve
lifter, and take the shim out.

NOTE:
By using a magnet (A), the shim (B) can be taken
out without dropping it.

3) Measure thickness of shim with micrometer.

4) Select a shim of suitable thickness using mea-
sured valve clearance and shim thickness, by refer-
ring to the following table.
5) Set suitable shim selected in step 4) to valve lift-
er.

6) Inspect all valves for clearance again at this
stage. If the valve clearance is not correct, repeat
the procedure over again from the first step.
7) After inspection, install the related parts in the
reverse order of removal.
