Check for cracks (A) and any excessive wear (B) 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 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, 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 leak age 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:
* Transaxle fluid, power steering fluid, brake fluid, etc.

5. Support the bottom surface of engine using a trans
mission jack, and then remove the engine mounting
bracket and insulator (RH). Refer to EM-88, " Exploded View " .
6. Remove rocker cover. Refer to EM-46, " Exploded View " .
7. Set No. 1 cylinder at TDC of its comp ression stroke with the following procedure:
a. Rotate crankshaft pulley (2) clockwise and align TDC mark (without paint mark) (A) to timing indicator (1) on front cover.
b. Make sure the matching marks on each camshaft sprocket are positioned as shown.
• If not, rotate crankshaft pulley one more turn to align matching marks to the positions.
8. Remove crankshaft pulley with the following procedure:
a. Secure crankshaft pulley (1) using a suitable tool (A).
b. Loosen and pull out crankshaft pulley bolts. CAUTION:
Never remove the bolts as they are used as a supporting
point for the pulley puller.
c. Attach Tool (A) in the M 6 thread hole on crankshaft pulley, and remove crankshaft pulley.
9. Remove front cover with the following procedure: B : White paint mark (Not use for service) PBIC3673E

a. Loosen bolts in the reverse of the order shown.
b. Cut liquid gasket by prying the position ( ) shown, and then remove the front cover.
10. Remove camshaft position sensor (PHASE) from rear end of cylinder head. CAUTION:
Handle it carefully and avoid impacts.
11. Remove 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.
12. 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. KBIA3429J

• 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 groove from the front of camshaft thrust (B).
• Proceed all the way through step “e” with the air pressure on.
• Attach the rubber nozzle (B) narrowed to the top of the air gun (A) to prevent air leakage from the oil hole. Securely apply the
air pressure to the oil hole.
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 sprocke t (INT) counterclockwise [the direction shown by the
arrow ( )].
• Perform the work while applying the air pressure to the oil hole. AWBIA0105ZZ

b. Disassemble the camshaft (1) from the camshaft sprocket (INT) (2).
c. Remove camshaft (INT). CAUTION:
Never damage the signal plate of rear end.
16. Remove valve lifter. • Identify installation positions, and store them without mixing them up.
17. Remove intake valve timing control solenoid valve (1).
18. Remove the generator and bracket, remove the plug (2), and then remove the washer and oil filter. Refer to SC-25, " Removal
and Installation " .
CAUTION:
Discard the washer, do not reuse.
