3. Remove camshaft sprocket (EXH) bolt and camshaft sprocket
(EXH) (1).
CAUTION:
• Hold the camshaft hexagonal part (A), and then secure the
camshaft.
• Never rotate crankshaft and camshaft separately, so as
not to contact valve with pist on in the following steps.
4. Turn the camshaft sprocket (INT) to the most advanced position. CAUTION:
Installation and removal of the camshaft sprocket (INT) must be done in the most advanced posi-
tion for the following reasons.
• The sprocket (C) and vane ( camshaft coupling) (B) are
designed to spin and move wi thin the range of a certain
angle.
• With the engine stopped and the vane in the most
retarded angle, it will not sp in because it is locked to the
sprocket side by the internal lock pin (A).
• If the camshaft sprocket bolts are turned in the situation
described above, the lock pi n will become damaged and
cause malfunctions because of the increased horizontal
load (cutting force) on the lock pin.
a. Remove camshaft bracket (No. 1) (1). • Loosen the bolts in several steps, and then remove them.
b. Apply the following air pressure to the No. 1 journal oil hole (A) of camshaft (INT) (1) shown using an air gun.
• Apply the air pressure into the oil hole on the second groovefrom the front of camshaft thrust.
• Proceed all the way through step “e” with the air pressure on.

• Attach the rubber nozzle narrowed to the top of the air gun to
prevent air leakage from the oil hole. Securely apply the air
pressure to the oil hole (A).
CAUTION:
• There are other oil holes in the side grooves. Never use the incorrect oil holes.
• Be sure not to damage the oil path with the tip of the air
gun.
• Wipe all the oil off the air gun to prevent oil from being
blown all over along with the air, and the area around the
air gun should be wiped wi th a rag when applying air
pressure. Eye protection should be worn as needed.
NOTE:
The air pressure is used to move the lock pin into the disengage position.
c. Hold the camshaft sprocket (INT) with hands, and then apply the power counterclockwise/clockwise alter-
natively.
• Finally rotate the sprocket of the camshaft sprocket (INT) counterclockwise [the direction shown by the
arrow ( )].
• Perform the work while applying the air pressure to the oil hole.
• If the lock pin is not released by hands, tap the camshaft sprocket (INT) (1) lightly with a plastic hammer.
• If the camshaft sprocket (INT) (1) is not rotated counterclock- wise even if the above procedures are performed, check the
air pressure and the oil hole position.
d. While doing the above, once you hear a click (the sound of the internal lock pin disengaging) from inside the camshaft sprocket
(INT), start turning the camshaft sprocket (INT) in the counter-
clockwise direction in the most advanced angle position.
• Keep the air pressure on.
• If there is no click, as soon as the vane-side (camshaft side)starts moving independently of the sprocket, the lock pin has
become disengaged.
• Make sure that it is in the most advanced angle position by seeing if the stopper pin groove (A) and the stopper pin hole (B) are matched up as shown.
e. Complete the applying procedure of air pressu re and the holding procedure of camshaft (INT).
f. Insert the stopper pin (A) into the stopper pin holes in the cam- shaft sprocket (INT) (1) and lock in the most advanced angle
position.
CAUTION:
No load is exerted on the stop per pin (spring reaction, etc.).
Since it comes out easily, secure it with tape (B) to prevent
it from coming out.
NOTE:
The stopper pin shows one example of a hexagonal wrench for
2.5 mm (0.098 in) [length of inserted section: approximately 15
mm (0.59 in)].

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 va
lve lifter outer diameter and valve lifter hole diame-
ter, replace either or both valve lifter and cylinder head.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak.
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
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, che ck 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, 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.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
• Perform this inspection only when DTC P0011 is de tected in self-diagnostic results of CONSULT-III
and it is directed according to inspect ion procedure of EC section. Refer to EC-127, "
Diagnosis Pro-
cedure".
• Check when engine is cold so as to pr event burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-7, "
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-496, "
Inspection".
