CAUTION:
Be careful not to scratch or make burrs on circumference
of oil seal.
 Using front oil seal drift (commerc ial service tool), press fit until
the height of front oil seal is level with the mounting surface.
 Make sure the garter spring is in position and seal lips not inverted.
9. Install chain tensioner cover to front cover.  Apply a continuous bead of liquid gasket with tube presser
(commercial service tool) to front cover as shown in the figure.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "

c. make sure again that the mating marks on timing chain and that on each sprocket are aligned. Then, install front cover.
CAUTION:
Be careful to avoid interferen ce with the front end of oil
pump drive spacer. Such interf erence may damage front oil
seal.
d. Tighten mounting bolts in numerical order as shown in the fig- ure.
 There are four type mounting bolts.
e. After all mounting bolts are tightened, retighten t hem in numerical order as shown in the figure.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking onto surface mating with oil pan.
11. Install intake valve timing control cover as follows:
a. At the back of intake valve timing control cover, in stall new seal rings (three for each bank) to the area to
be inserted into camshaft sprocket (INT).

TIMING CHAIN
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak. Before starting engine, check oil/fluid levels incl
uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-9, "
Fluids and Lubricants"
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
 Bleed air from lines and hoses of applic able lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

3. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
CAUTION:
 Do not loosen mounting bol ts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
 After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike the piston head.
4. Remove intake and exhaust camshaft brackets.  Mark camshafts, camshaft brackets and bolts so placed in the same position and direction for installa-
tion.
 Equally loosen camshaft brackets and bolts in several steps in reverse order as shown in the figure.
 Lightly tapping with plastic hammer, remove camshaft bracket (No. 1) and camshaft bracket (No. 6).
NOTE:
The bottom surface of each bracket will be stuck to cylinder
head because of liquid gasket.
5. Remove camshaft.
6. Remove valve lifter if necessary.  Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journalof camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a differe nt diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.

CAMSHAFT
 Install camshaft so that dowel pin on front end face are posi-
tioned as shown in the figure. (No. 1 cylinder TDC on its com-
pression stroke)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
3. Install camshaft brackets.  Remove foreign material completely from camshaft bracketbackside and from cylinder head installation face.
 Install by referring to installation location mark on upper sur-
face and front mark.
 Install so that installation location mark can be correctly read when viewed from the side of left exhaust bank.
 Apply liquid gasket to mating surface of camshaft bracket (No. 1) as shown in the figure.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
CAUTION:
 After installation, be sure to wipe off any excessive liq- uid gasket leaking from part “A” and “B” (both on right
and left sides).
 Remove completely any excess of liquid gasket inside bracket.
 Apply liquid gasket to mating surface of camshaft bracket (No. 6) on left bank intake as shown in the figure.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
CAUTION:
 After installation, be sure to wipe off any excessive liq- uid gasket leaking from part “A” and “B” (both on right
and left sides).
