TIMING CHAIN
Check for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
 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-19, "
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 chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise
will stop after hydraulic pressure rises.
 Warm up engine thoroughly to make sure there is no leakage of fuel, 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.

Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
 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-131, "
Diagnosis Pro-
cedure" (EURO-OBD), EC-484, "Diagnosis Procedure" (WITHOUT EURO-OBD).
 Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-6, "
Inspection".
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release the fuel pressure. Refer to EC-377, "
Inspection" (EURO-OBD), EC-681, "Inspection" (WITHOUT
EURO-OBD).
b. Remove intake manifold. Refer to EM-29, "
Exploded View".
c. Disconnect ignition coil and injector harness connectors. Refer to EM-47, "
Exploded View".
3. Remove intake valve timing control solenoid valve. Refer to EM-50, "
Exploded View".
4. Crank engine, and then make sure that engine oil comes out
from intake valve timing control solenoid valve hole (A). End
crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
 Prevent splashing by using a shop cloth so as to prevent
the worker from injury from engine oil and so as to prevent engine oil contamination.
 Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.

In this step, loosen bolts in reverse order of that indicated.
d. Tighten all bolts.
e. Turn all bolts 75 degrees clockwise (angle tightening).
CAUTION:
Check and confirm the tightening angle by using the angle
wrench [SST: KV10112100] (A) or protractor. Avoid judg-
ment by visual inspection without the tool.
f. Turn all bolts 75 degrees clockwise again (angle tightening).
3. Installation is in the reverse order of removal, for the remaining parts.
