(6)   Disconnect spark plug cords from spark plugs (#2 and #4 cylinders).
(7)   Place suitable container under the vehicle.
(8)   Disconnect PCV hose from rocker cover (LH).
(9)   Remove bolts, then remove rocker cover (LH).
11) Turn crankshaft pulley clockwise until arrow mark on camshaft sprocket is set to position shown in figure.
NOTE:
Turn crankshaft using ST.
ST 499987500 CRANKSHAFT SOCKET
13)   If necessary, adjust the valve clearance. <Ref. to ME(DOHC TURBO)-30, ADJUSTMENT, Valve Clearance.>
14)   Further turn crankshaft pulley clockwise. Using the same procedures described previously, then measure valve clearances again.
(1) Set arrow mark on camshaft sprocket to position shown in figure, and measure #2 cylin­der exhaust valve and #3 cylinder intake valve clearances.
for_01_22-357.jpg
for_01_22-358.jpg
12) Measure #1 cylinder intake valve and #3 cyl­inder exhaust valve clearance by using thickness gauge (A).
CAUTION:
•  Insert the thickness gauge in as horizontal a direction as possible with respect to the shim.
•   Measure exhaust valve clearances while lift-ing-up the vehicle.
Valve clearance:
Intake: 0.20±0.02 mm (0.0079±0.0008 in) Exhaust: 0.25±0.02 mm (0.0098±0.0008 in)
(2) Set arrow mark on camshaft sprocket to position shown in figure, and measure #2 cylin­der intake valve and #4 cylinder exhaust valve clearances.

B: ADJUSTMENT
S183083A01
CAUTION:
Adjustment of valve clearance should be per­formed while engine is cold.
1) Measure all valve clearances. <Ref. to ME(DOHC TURBO)-28, INSPECTION, Valve Clearance.>
NOTE:
Record each valve clearance after it has been
measured.
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.
4)  Select a shim of suitable thickness using mea­sured valve clearance and shim thickness, by referring to the following table.
5)  Set suitable shim selected in step 4) to valve lifter.
