CAMSHAFT

Measure the diameter of valve lifter hole of cylinder head with an
inside micrometer (A).

VALVE LIFTER CLEARANCE
• (Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter

outer diameter)

• If out of the standard, referring to the each standard of valve lifter

outer diameter and valve lifter hole diameter, replace either or both
valve lifter and cylinder head.

INSPECTION AFTER INSTALLATION

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-706, "Diagnosis

Description"

.

• Check when engine is cold so as to prevent burns by the splashing engine oil.

1.

Check engine oil level. Refer to

LU-14, "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-978, "Inspection"

.

b.

Remove intake manifold. Refer to

EM-146, "Exploded View"

.

c.

Disconnect ignition coil and injector harness connectors.

3.

Remove intake valve timing control solenoid valve. Refer to

EM-162, "Exploded View"

.

4.

Clean the mounting area of intake valve timing control solenoid
valve, and then insert a clean waste with no oil adhesion into the
oil hole (A) of the cylinder head.

5.

Install engine mounting insulator (RH). (After the removal of
intake valve timing control solenoid valve and insertion of a
waste into the oil hole.)

6.

Perform cranking to check that engine oil comes out from the oil hole (mounting hole of intake valve timing
control solenoid valve) of cylinder head.
• Regarding the engine oil check, judge it by the amount of oil adhered to the wasted inserted into the oil

hole.

WARNING:

• Never insert fingers into the oil hole from the service hole of the member on the RH side.
• Be careful not to touch rotating parts (drive belt, idler pulleys and crankshaft pulley, etc.).

CAUTION:

• Never perform cranking without installing the engine mounting insulator (RH).
• 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 belt,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.

7.

Perform the following inspection if engine oil does not come out from intake valve timing control solenoid
valve oil hole of the cylinder head.

• Remove oil filter (for intake valve timing control solenoid), and then clean it. Refer to

EM-162, "Exploded

View"

.

• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to

LU-11,

"Engine Lubrication System"

and

LU-11, "Engine Lubrication System Schematic"

.

8.

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-11, "Engine Lubrication System"

and

LU-11, "Engine Lubrica-

tion System Schematic"

.

9.

After inspection, install removed parts in the reverse order.

VALVE OIL SEAL : Removal and Installation

INFOID:0000000000893953

REMOVAL

1.

Remove camshafts. Refer to

EM-173, "Exploded View"

.

2.

Remove valve lifters. Refer to

EM-173, "Exploded View"

.

3.

Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve
from dropping into cylinder.

CAUTION:

When rotating crankshaft, be careful to avoid scarring front cover with timing chain.

4.

Remove valve collet.
• Compress valve spring with the valve spring compressor, the

attachment and the adapter [SST: KV10116200] (A).

CAUTION:

Be careful not to damage valve lifter holes.

5.

Remove valve spring retainer, valve spring and valve spring seat.

6.

Remove valve oil seal with the valve oil seal puller [SST:
KV10107902] (A).

INSTALLATION

1.

Apply new engine oil to valve oil seal joint surface and seal lip.

2.

Press in valve oil seal to the height “H” shown in the figure with
the valve oil seal drift [SST: KV10115600] (A).

3.

Install in the reverse order of removal, for the rest of parts.
