CAMSHAFT
Valve Lifter Clearance
VALVE LIFTER OUTER DIAMETER
• Measure the outer diameter of valve lifter with a micrometer (A).
VALVE LIFTER HOLE DIAMETER
Measure the inner 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 and
it is directed according to inspection procedure of EC section. Refer to
.
• Check when engine is cold so as to prevent burns by the splashing engine oil.
1.
Check engine oil level. Refer to
.
2.
Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a.
Release the fuel pressure. Refer to
.
b.
Remove intake manifold. Refer to
c.
Disconnect ignition coil and injector harness connectors.
d.
Support the bottom surface of engine using a transmission jack, and then remove the engine mounting
bracket (RH) and engine mounting insulator (RH). Refer to
3.
Remove intake valve timing control solenoid valve. Refer to
• Lift the front side of the engine with a jack base to remove intake valve timing control solenoid valve.
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 of the cylinder head.
5.
Install engine mounting insulator (RH) and engine mounting bracket (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.
• 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) and engine mount-
ing bracket (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), and then clean it. Refer to
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to
LU-2, "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-2, "Engine Lubrication System"
and
9.
After inspection, install removed parts in the reverse order.

INFOID:0000000009944951
REMOVAL
1.
Remove camshafts. Refer to
2.
Remove valve lifters. Refer to
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 [SST:
KV10116200 (J-26336-A)] (A), the attachment [SST:
KV10115900 (J-26336-20)] (C), and the adapter [SST:
KV10109220 (
—
)] (B). Remove valve collet with magnet
hand.
CAUTION:
Be careful not to damage valve lifter holes.
5.
Remove valve spring retainer and valve spring (with valve spring seat).
CAUTION:
Never remove valve spring seat from valve spring.
6.
Remove valve oil seal with the valve oil seal puller [SST:
KV10107902 (J-38959)] (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 (J-38958)] (A).
3.
Install in the reverse order of removal, for the rest of parts.
