3. Install the RH bank (B) and LH bank (D) camshaft brackets (A).

• Install by referring to the installation location mark (E) on the

upper surface.

• Install so that the installation location mark (E) can be correctly

read when viewed from the intake manifold side (C).

• Install No. 1 camshaft bracket using the following procedure:

• C:11 mm (0.43 in)

• D: 2.0 - 3.0 mm (0.079 - 0.118 in) dia.

- Apply liquid gasket to No. 1 camshaft bracket (A) and (B) as

shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

CAUTION:

• After installation, be sure to wipe off any excessive liq-

uid gasket outside of application (C) and (D) both on RH

and LH sides.

• Remove completely any excess of liquid gasket inside

bracket.

- Apply liquid gasket (C) to the back side of the LH (A) bank

front cover and RH (B) bank front cover as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

- C:2.6 - 3.6 mm (0.102 - 0.142 in) dia.

5. Install the camshaft sprockets using the following procedure:

• A: LH bank shown

a. Install the camshaft sprockets aligning them with the matching

marks painted on the timing chain (B) and the camshaft sprock-

ets (C) before removal. Align the camshaft sprocket key groove

with the dowel pin on the camshaft front edge at the same time.

Then temporarily tighten camshaft sprocket bolts.

• Install the intake (VTC) (A) and exhaust (B) side camshaft

sprockets by selectively using the groove of the dowel pin

according to the bank for the exhaust (B) side camshaft

sprockets. (Common part used for both exhaust banks.)

NOTE:

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

b. Lock the hexagonal part of the camshaft in the same way as for

removal, and tighten the camshaft sprocket bolts.

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

and on each sprocket are aligned.

6. Install the chain tensioner using the following procedure:

NOTE:

LH is shown.

a. Install the chain tensioner.

• Compress the plunger and hold it using a stopper pin when

installing.

• Loosen the slack guide side timing chain by rotating the cam-

shaft hexagonal part if mounting space is small.

b. Remove the stopper pin and release the plunger, and then apply

tension to the timing chain.

c. Install the chain tensioner cover onto the front cover.

• Apply liquid gasket as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

7. Check and adjust valve clearances. Refer to

EM-18, "Valve

Clearance"

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

of removal.

CAMSHAFT

Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT III and

it is directed according to inspection procedure of EC section. Refer to

EC-142, "On Board Diagnosis

Logic"

1. Check engine oil level. Refer to

LU-8, "Inspection"

2. Perform the following procedure so as to prevent the engine from being unintentionally started while

checking.

a. Release fuel pressure. Refer to

EC-473, "Fuel Pressure Check"

b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove IVT control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from IVT control cover oil hole. End cranking

after checking.

WARNING:

Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).

CAUTION:

• Engine oil may squirt from IVT control solenoid valve installation hole during cranking. Use a

shop cloth to prevent engine oil from splashing on worker, engine components and vehicle.

• Do not allow engine oil to get on rubber components such as drive belts or engine mount insula-

tors. Immediately wipe off any splashed engine oil.

5. Clean oil groove between oil strainer and IVT control solenoid valve if engine oil does not come out from

IVT control valve cover oil hole. Refer to

LU-7, "Schematic"

6. Remove components between IVT control solenoid valve and camshaft sprocket (INT), and then check

each oil groove for clogging.

• Clean oil groove if necessary.

7. After inspection, installation of the remaining components is in the reverse order of removal.
