VALVE LIFTER HOLE DIAMETER

Measure inner diameter of valve lifter hole of cylinder head with
inside micrometer.
VALVE LIFTER CLEARANCE

(Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)

If out of the standard, referring to each standard of valve lifter outer diameter and valve lifter hole diame-
ter, replace either or both valve lifter and cylinder head.
INSTALLATION
1. Install timing chain tensioners (secondary) on both cylinder
heads (right and left banks).

Install timing chain tensioner (secondary) with its stopper pin
attached.

Install timing chain tensioner (secondary) with sliding part fac-
ing downward on cylinder head (right bank), and with sliding
part facing upward on cylinder head (left bank).

Install new O-ring as shown in the figure.
2. Install valve lifters.

Install them in the original position.
3. Install camshafts.

Install camshaft with dowel pin attached to its front end face
on the exhaust side.Standard

cal order as shown in the figure.
a. Tighten No. 7 to 10 in order as shown.
b. Tighten No. 1 to 6 in order as shown.
c. Tighten No. 1 to 10 in numerical order as shown.
d. Tighten No. 1 to 10 in numerical order as shown.
CAUTION:
After tightening mounting bolts of camshaft brackets (No.
1), be sure to wipe off excessive liquid gasket from the
parts list below.

Mating surface of rocker cover

Mating surface of rear timing chain case
6. Measure the difference in levels between front end faces of
camshaft bracket (No. 1) and cylinder head.

Measure two positions (both intake and exhaust side) for a
single bank.

If measured value is out of the standard, re-install camshaft
bracket (No. 1).
7. Check and adjust the valve clearance. Refer to EM-202, "
Valve Clearance" .
8. Install in the reverse order of removal after this step. : 1.96 N·m (0.20 kg-m, 1 ft-lb)

INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:

Perform this inspection only when DTC P0011 or P0021 are detected in self-diagnostic results of
CONSULT-II and it is directed according to inspection procedure of EC section. Refer to EC-427,
"SELF-DIAG RESULTS MODE" .

Check when engine ins cold so as to prevent burns from any splashing engine oil.
1. Check the engine oil level. Refer to LU-19, "
ENGINE OIL" .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to EC-392, "
FUEL PRESSURE RELEASE" .
b. Disconnect ignition coil and injector harness connectors.
3. Remove intake manifold control solenoid valve. Refer to EM-192, "
CAMSHAFT" .
4. Crank the engine, and then make sure that engine oil comes out
from camshaft bracket (No. 1) oil hole. End crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
Engine oil may squirt from intake valve timing control sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do
not allow engine oil to get on rubber components such as
drive belt or engine mount insulators. Immediately wipe off
any splashed engine oil.

Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not
come out from camshaft bracket (No. 1) oil hole. Refer to LU-17, "
LUBRICATION SYSTEM" .
5. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.

Clean oil groove if necessary. Refer to LU-17, "LUBRICATION SYSTEM" .
6. After inspection, install removed parts.
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

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-14, "
RECOMMENDED 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
leakage 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/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 gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable 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.
