4. Disconnect fuel feed hose from hose clamp.
NOTE:
There is no fuel return path.
5. With the sleeve side of quick connector release facing quick connector, install quick connector release onto fuel tube.
6. Insert quick connector release into quick connector until sleeve contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector re lease hard will not disconnect
quick connector. Hold qui ck connector release where it
contacts and goes no further.
7. Draw and pull out quick connector straight from fuel tube. CAUTION:
• Pull quick connector holding (A) position.
• Do not pull with lateral force applied. O-ring inside quick connector may be damaged.
• Prepare container and cloth be forehand as fuel will leak out.
• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick co nnector and fuel feed hose during installation/
removal.
• To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
8. Remove intake manifold. Refer to EM-137

• Check timing chain and oil pump drive chain for cracks (A) and any
excessive wear (B) at the roller links of timing chain.
• Replace timing chain and/or oil pum p drive chain, if necessary.
INSTALLATION
NOTE:
The figure shows the relationship between the matching mark on
each timing chain and that on the corresponding sprocket, with the
components installed.
1. Make sure that crankshaft key points are aligned.
NOTE:
*: There are two outer grooves in camshaft spro cket (INT). The wider one is a matching mark.
2. If the timing chain tension guide (front cover si de) is removed, install it to the front cover.
CAUTION:
Check the joint condition by sound or feeling.
3. Install crankshaft sprocket (2), oil pump sprocket (3) and oil pump drive chain (1).
• Install it by aligning matching marks on each sprocket and oil
pump drive chain.
• If these matching marks are not aligned, rotate the oil pump
shaft slightly to correct the position.
CAUTION:
Check matching mark position of each sprocket after
installing the oil pump drive chain.

4. Clean the mating area of intake valve timing control solenoid
valve. Insert a clean shop cloth (with no oil adhesion) into the oil
hole (A) of the cylinder head.
5. Install engine mounting bracket (RH), engine mounting insulator, and torque rod (RH) under the Step 4 condition. (With intake
valve timing control solenoid valve removed, and a shop cloth
inserted into the oil hole.) Refer to EM-191, "
Component".
6. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End cranking after checking.
• Check engine oil leakage by oil amount adhered to the shop cloth inserted into the oil hole.
WARNING:
• Be careful not to touch rotating parts (drive be lts, idler pulley, and crankshaft pulley, etc.).
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engi ne oil contamination.
CAUTION:
• Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.
• 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 engi ne 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 EM-195, "
Component".
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-16
.
8. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-16
.
9. Installation of the remaining components is in the reverse order of removal

INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-149
.
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke. • Rotate crankshaft pulley (1) clockwise and align TDC mark (no paint) (B) to timing indicator (A) on front
cover.

CYLINDER HEAD
• If the engine speed is out of the specified range, c
heck battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
• If compression pressure is below minimum val ue, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, pi ston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
• If one cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, pi ston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal- functioning. Check valves for damage. Repl ace valve or valve seat accordingly.
• If two adjacent cylinders have respectively low co mpression pressure and their compression remains
low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
9. After inspection is completed, install removed parts.
10. Start the engine, and confirm that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-585, "
Trouble Diagnosis Introduction".

• If clearance exceeds the limit, select proper main
bearing according to main bearing inner diameter and
crankshaft main journal diameter to obtain specified bearing oil clearance. Refer to EM-205, "
How to Select
Piston and Bearing".
Method of Using Plastigage
• Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely.
• Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
• Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec- ified torque. Refer to EM-196, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Never rotate crankshaft.
• Remove main bearing cap and bearings, and using the scale (A) on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING CRUSH HEIGHT
• When main bearing cap is removed after being tightened to thespecified torque with main bearings (1) installed, the tip end of
bearing must protrude (B). Refer to EM-196, "
Disassembly and
Assembly" for the tightening procedure.
• If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
• When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings (1) installed,
the tip end of bearing must protrude. Refer to EM-196, "
Disassem-
bly and Assembly" for the tightening procedure (B).
• If the standard is not met, replace connecting rod bearings.
