TIMING CHAIN
2. Install the camshaft sprockets.
• Install the camshaft sprocket INT (valve timing control) (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 timing 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 timing chain tensioner with the plunger locked in with the stopper pin.
CAUTION:
• Before and after the installation of the timing chain tensioner, make sure that the alignment
mark on the timing chain is not out of alignment.
• After installing the timing chain tensioner, remove the stopper pin to release the tensioner.
Make sure the 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.
8. Installation of the remaining components is in the reverse order of removal. Refer to

• 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-15, "FOR NORTH AMERICA : Fluids and Lubricants"
States and Canada) or
MA-16, "FOR MEXICO : 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, 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.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

5. Obtain compression TDC of No. 1 cylinder as follows:
a. Turn the crankshaft pulley clockwise to align the TDC identifica-
tion notch (without paint mark) with the timing indicator on the
front cover.
b. At this time, make sure both intake and exhaust cam lobes of
No. 1 cylinder (top front on LH bank) point outside.
• If they do not point outside, turn crankshaft pulley once more.
6. Disconnect and remove the camshaft position sensor. Refer to
7. Disconnect and remove the intake valve timing control position sensor (RH and LH). Refer to
8. Disconnect and remove the intake valve timing control solenoid valve (RH and LH). Refer to
9. Remove the intake valve timing control solenoid valve cover
(RH) (A) and intake valve timing control solenoid valve cover
(LH) (B) as follows:
a. Loosen and remove the bolts in reverse order as shown.
b. Cut the liquid gasket and remove the covers using Tool.
CAUTION:
Do not damage mating surfaces.
10. Paint alignment marks on the (RH) bank (A) timing chain links
(C) and (LH) bank (B) timing chain links (D) and align with the
camshaft sprocket alignment marks (E) and (F).
11. Remove the chain tensioner (LH) using the following steps.
WARNING:
Plunger, spring, and spring seat pop out when squeezing return-proof clip without holding
