12.INSPECT PISTON PIN OIL CLEARANCE
a. Inspect the piston pin oil clearance.
1. Using a caliper gauge, measure the inside diameter of the connecting rod bushing.
Bushing inside diameter:
22.005 to 22.014 mm (0.8663 to 0.8667 in.)
If the bushing inside diameter is not as specified, check the oil clearance.
2. Subtract the piston pin diameter measurement (see step 10) from the bush inside diameter
measurement.

b. Inspect the main journals and crank pins.
1. Using a micrometer, measure the diameter of each main journal and crank pin.
Main journal diameter:
66.988 to 67.000 mm (2.6373 to 2.6378 in.)
Crank pin diameter:
51.982 to 52.000 mm (2.0465 to 2.0472 in.)
If the diameter is not as specified, check the oil clearance (see steps 3 and 7). If necessary, replace
the crankshaft.
2. Check each main journal and crank pin for taper and out-of-round as shown in the illustration.
Maximum taper and out-of-round:
0.02 mm (0.0008 in.)

connecting rod cap bolts.
3. Mark the front of the connecting cap bolt with paint.
4. Retighten the cap bolts 90° as shown in the illustration.
5. Check that the painted mark is now at a 90° angle to the front.
d. Check that the crankshaft turns smoothly.
e. Check the connecting rod thrust clearance (see step 2).
27.INSTALL WATER SEAL PLATE
a. Remove any old packing (FIPG) material and be careful not to drop any oil on the contact surfaces
of the seal plate and cylinder block.

Using a razor blade and gasket scraper, remove all the old packing (FIPG) material from the
gasket surfaces and sealing groove.
Thoroughly clean all components to remove all loose material.
Using a non-residue solvent, clean both sealing surfaces.
b. Apply seal packing to the seal plate as shown in the illustration.
Seal packing: Part No. 08826-00080 or equivalent

f. Observe these precautions when connecting the fuel tube connector (quick type).
1. Check that there is no damage or foreign matter on the part of the pipe that contacts the
connector.
2. Align the axis of the connector with the axis of the pipe. Push the pipe into the connector
until the connector makes a `click' sound. If the connection is too tight, apply a small amount
of fresh engine oil on the tip of the pipe.

3. After connecting the pipe and connector, try to pull them apart to confirm that they are
securely connected.
4. Install the No. 1 fuel pipe clamp to the connector.

ON-VEHICLE INSPECTION
1.INSPECT IGNITION COIL ASSY (WITH IGNITER) AND PERFORM SPARK TEST
a. Check for DTCs.
b. Check if sparks occur.
1. Remove the ignition coil (see REPLACEMENT
).
2. Remove the spark plug.
3. Install the spark plug to the ignition coil, and connect the ignition coil connector.
4. Disconnect the 8 injector connectors.
5. Ground the spark plu

7. Using a 16 mm (0.63 in.) plug wrench, install the spark plugs.
Torque: 18 N.m (180 kgf.cm, 13 ft.lbf)
8. Install the ignition coils (see REPLACEMENT
).
