3. Install the front cover as follows:
a. Install a new O-ring on the cylinder block.

CAUTION:

Do not reuse O-ring.

b. Apply liquid gasket as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

.

CAUTION:

The components must be installed within 5 minutes of the

liquid gasket application. Then allow 30 minutes for the liq-

uid gasket to set before operating the engine.

c. Check again that the timing alignment marks on the timing chain

and on each sprocket are aligned. Then install the front cover.

d. Install the bolts in the numerical order as shown.

e. After tightening, re-tighten to the specified torque.

CAUTION:

Be sure to wipe off any excessive liquid gasket leaking onto

surface mating with oil pan.

4. Install the intake valve timing control solenoid valve cover (RH)

(A) and intake valve timing control solenoid valve cover (LH) (B)

as follows:

• *: Cross mark (C) that cannot be seen after assembly

a. Apply liquid gasket (D) as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

.

CAUTION:

The components must be installed within 5 minutes of the liquid gasket application. Then allow 30

minutes for the liquid gasket to set before operating the engine.

CAUTION:

The start and end of the liquid gasket application should be crossed at a position (C) that cannot

be seen after attaching the cover.

b. Install the bolts in the numerical order as shown.

• A: Intake valve timing control solenoid valve cover (RH)

• B: Intake valve timing control solenoid valve cover (LH)

5. Install the crankshaft pulley.

• Install the key of the crankshaft.

• Insert the pulley by lightly tapping it.

CAUTION:

Do not tap pulley on the side surface where the belt is installed (outer circumference).

6. Tighten the crankshaft pulley bolt.

• Lock the crankshaft using suitable tool, then tighten the bolt. 

• Perform the following steps for angular tightening:

a. Apply engine oil onto the threaded parts of the bolt and seating area.
b. Select the one most visible notch of the four on the bolt flange.

Corresponding to the selected notch, put a alignment mark

(such as paint) on the crankshaft pulley. 

7. Rotate the crankshaft pulley in normal direction (clockwise when

viewed from engine front) to check for parts interference.

8. Installation of the remaining components is in the reverse of order of removal.

INSPECTION AFTER INSTALLATION

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to 

MA-18, "FOR USA AND CANADA : Fluids and Lubricants"

 (United

States and Canada).

• 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, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide

may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop

after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-

ified level, if necessary.

Removal and Installation

INFOID:0000000006247086

NOTE:

• To remove timing chain and associated parts, start with those on the LH bank. The procedure for removing

parts on the RH bank is omitted because it is the same as that for removal on the LH bank.

• To install timing chain and associated parts, start with those on the RH bank. The procedure for installing

parts on the LH bank is omitted because it is the same as that for installation on the RH bank.

REMOVAL

1. Remove timing chain cover. Refer to 

EM-188, "Removal and Installation"

.

2. Without removing them, loosen the camshaft sprocket bolts. 
3. Remove the oil pump drive spacer.

• Hold and remove the flat space of the oil pump drive spacer by

pulling it forward. 

4. Remove the oil pump. Refer to 

LU-32, "Removal and Installation"

.

5. Remove the chain tensioner on the LH bank using the following steps.

NOTE:

To remove the timing chain and associated parts, start with those on the LH bank. The procedure for

removing parts on the RH bank is omitted because it is the same as that for the LH bank. 

a. Squeeze the return-proof clip ends using suitable tool and push

the plunger into the tensioner body.

b. Secure the plunger using stopper pin.

• Stopper pin is made from hard wire approximately 1 mm (0.04

in) in diameter.

c. Remove the bolts and chain tensioner.

WARNING:

Plunger, spring, and spring seat pop out when (squeezing)

return-proof clip without holding plunger head. It may

cause serious injuries. Always hold plunger head when

removing.

TIMING CHAIN

• Stop the plunger in the fully extended position by using the

return-proof clip (1) if the stopper pin is removed.

• Push the plunger (2) into the tensioner body while squeezing

the return-proof clip (1). Secure it using stopper pin (3).

6. Remove the timing chain tension guide and timing chain slack guide.
7. Remove the timing chain and crankshaft sprocket.
8. Loosen the camshaft sprocket bolts by holding the camshaft at

point (A) using a suitable tool as shown. Remove the camshaft

sprocket.

CAUTION:

To avoid interference between valves and pistons, do not

turn crankshaft or camshaft when timing chain is discon-

nected.

9. Repeat the same procedure to remove the RH timing chain and associated parts.

INSPECTION AFTER REMOVAL

Check for cracks and any excessive wear at link plates. Replace

chain if necessary.

• In the same way as for the LH bank, inspect the timing chain and

associated parts on the RH bank.

TIMING CHAIN

2. Install the camshaft sprockets.

• Install the camshaft sprocket INT (VTC) (A) and camshaft

sprockets EXH (B) by selectively using the groove of the

dowel pin according to the bank. (Common part used for both

exhaust banks.) 

NOTE:

Use the groove marked (R) for RH bank and (L) for LH bank.

• Lock the hexagonal part of the camshaft in the same way as

for removal, and tighten the bolts.

3. Install the crankshaft sprockets for both banks.

• Install LH bank crankshaft sprocket (B) and RH bank crank-

shaft sprocket (C) so that their flange side (A) (the larger diam-

eter side without teeth) faces in the direction shown.

NOTE:

The same parts are used but facing directions are different.

4. Install the timing chains and associated parts.

• Align the alignment mark on each sprocket and the timing chain for installation.

CAUTION:

• Before installing chain tensioner, it is possible to change the position of alignment mark on

timing chain and each sprocket. After the alignment marks are aligned, keep them aligned by

holding them by hand.

• Install the slack guides and tension guides onto the correct side by checking the identification mark on

the surface.

• Install the chain tensioner with the plunger locked in with the stopper pin.

CAUTION:

• Before and after the installation of the chain tensioner, make sure that the alignment mark on

the timing chain is not out of alignment.

• After installing the chain tensioner, remove the stopper pin to release the chain tensioner.

Make sure the chain tensioner is released.

• To avoid chain-link skipping of the timing chain, do not move crankshaft or camshafts until the

front cover is installed.

5. In the same way as for the RH bank, install the timing chain and associated parts on the LH bank.
6. Install the oil pump. 
7. Install the oil pump drive spacer as follows:

• Install so that the front mark on the front edge of the oil pump

drive spacer faces the front of the engine.

• Insert the oil pump drive spacer according to the directions of

the crankshaft key and the two flat surfaces of the oil pump

inner rotor. 

• If the positional relationship does not allow the insertion, rotate

the oil pump inner rotor to allow the oil pump drive spacer to

be inserted.
