CAUTION:
Apply new engine oil to parts marked in illustration before installation.
●This engine will have a different valve arrangement from normal
DOHC 4-valve type engines. As both camshafts on this engine
have intake and exhaust camshafts, in this chapter they are
named as follows:
●Refer to the figure for intake and exhaust valve arrangement.
(The camshafts have, alternately, either an intake valve or an
exhaust valve.)

INSPECTION
●When the camshaft or parts in connection with valves are
removed or replaced, and a malfunction has occurred (poor
starting, idling, or other malfunction) due to the misadjustment of
the valve clearance, inspect as follows.
●Inspect and adjust when the engine is cool (at normal tempera-
ture).
●Be careful of the intake and exhaust valve arrangement. The
valve arrangement is different from that in a normal engine.
NOTE:
The camshafts have, alternately, either an intake valve or an
exhaust valve.(Refer to illustration)
1. Drain engine coolant. Refer to CO-29, "
Changing Engine Coolant" .
2. Remove charge air cooler. Refer to EM-122, "
Removal and Installation" .
3. Remove air duct and air inlet pipe. Refer to EM-120, "
Removal and Installation" .
4. Remove rocker cover. Refer to EM-156, "
Removal and Installation" .
5. Remove vacuum pump. Refer to EM-139, "
Removal and Installation" .
6. Remove injection tube and fuel injector. Refer to EM-144, "
Removal and Installation" .
7. Remove secondary timing chain. Refer to EM-167, "
Removal and Installation"
Check valve clearance while engine is cold and not running.
8. Set the No. 1 piston to TDC on its compression stroke.
●Turn crankshaft pulley clockwise so that the knock pin on
camshaft LH faces straight above. (No position indicator, etc.
is provided on the crankshaft pulley.)
9. Put an alignment mark with paint, etc. on the crankshaft pulley
and on the oil pump as an angle indicator.
10. While referring to the figure, measure the valve clearance
marked in the table below.
●The injection order is 1-3-4-2.

CAUTION:
●After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.
●When installing camshafts, chain tensioners, oil seals or other sliding parts, lubricate contacting
surfaces with new engine oil.
●Apply new engine oil to parts marked in illustration before installation.
REMOVAL
●For preparative work for removing/installing secondary timing chain to remove/install electronic fuel supply
pump. Refer to EM-147, "
FUEL SUPPLY PUMP" .
●To prepare for removing/installing secondary timing chain to remove/install camshaft. Refer to EM-158,
"Removal and Installation" .
1. Remove engine coolant reservoir tank.
2. Remove RH engine mount insulator and bracket. Refer to EM-193, "
Removal and Installation" .
3. Pull power steering reservoir tank out of brackets to move power steering piping.
CAUTION:
To avoid removing power steering reservoir tank out of brackets move it with power steering pip-
ing aside.

4. Remove front chain case.
●Loosen fixing bolts in the reverse order of that shown in the
figure and remove them.
●Remove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
●While front chain case is removed, cover openings to
prevent entry of foreign material into engine.
●Do not remove two mass dampers on the back of
cover.
5. Set the No. 1 piston to TDC on its compression stroke.
●Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
●No position indicator is provided on the crankshaft pul-
ley.
●When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
supply pump sprocket may not be easy to see.
6. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.
b. Using a hexagon-head wrench [face to face: 5 mm, (0.20 in)
SST], remove bolts to remove chain tensioner.
