Main Bearing Clearance Inspection
Main Bearing-to-Journal Oil Clearance
No.1,2,4,5Journals:
Standard (New): 0.017 0.041 mm (0.0007 0.0016 in.)
Service Limit: 0.050 mm (0.0020 in.)

Service Limit: 0.055 mm (0.0022 in.)

Crankshaft Main Bearing Replacement
1. To check the main bearing-to-journal oil clearance,
remove the lower block and the bearing halves
(see page 7-13).
2. Clean each main journal and bearing half with a clean shop towel.
3. Place one strip of plastigage across each main journal.
4. Reinstall the bearings and lower block, then tighten the bolts to 29 N·m (3.0 kgf·m, 22 lbf·ft) 56 ° in
thepropersequence(seestep19onpage7-27).
NOTE: Apply new engine oil to the bolt threads and flanges.
 Do not rotate the crankshaft during inspection.
5. Remove the lower block and the bearings again, and measure the widest part of the plastigage. 6. If the plastigage measures too wide or too narrow,
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing with
the appropriate color code(s), and recheck the
clearance. Do not file, shim, or scrape the bearings
or the caps to adjust clearance.
7. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the
color listed above or below the current one), and
check again. If the proper clearance cannot be
obtained by using the appropriate larger or smaller
bearings, replace the crankshaft, and start over.

3. Use the crank bore codes and crank journal codes
to select the appropriate replacement bearings
from the following table.
NOTE: Color code is on the edge of the bearing.
 When using bearing halves of different colors, it does not matter which color is used in the top or
bottom. 1. Remove the oil pump (see page 8-16).
2. Remove the baffle plates (see step 8 on page 7-13).
3. Remove the connecting rod cap and the bearing
half.
4. Clean the crankshaft rod journal and the bearing half with a clean shop towel.
5. Place plastigage across the rod journal.
6. Reinstall the bearing half and connecting rod cap, and tighten the bolts to 20 N·m (2.0 kgf·m, 14 lbf·ft)90 ° (K20Z2 engine) or 29 N·m (3.0 kgf·m,
22 lbf·ft) 90 ° (K20Z3 engine).
NOTE:  Apply new engine oil to the bolt threads and flanges.

11-322 Fuel Supply System
Fuel Pressure Relieving
A
A
A
Before disconnecting fuel lines or hoses, relieve
pressure from the system by disabling the fuel pump
and then disconnecting the fuel tube/quick connect
fitting in the engine compartment. 1. Turn the ignition switch to LOCK (0).
2. Connect the HDS to the data link connector (DLC) (A) located under the driver’s side of the dashboard.
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the ECM/ PCM. If it doesn’t, go to the DLC circuit
troubleshooting (see page 11- 204).
5. Turn the ignition switch to LOCK (0).
6. Remove the fuel fill cap to relieve the pressure in the fuel tank.
7. Turn the ignition switch to ON (II).
8. From the INSPECTION MENU of the HDS, select Fuel Pump OFF, then start the engine, and let it idle
until it stalls.
NOTE: Do not allow the engine to idle above 1,000 rpm or the ECM/PCM will continue to operate the fuel
pump.
 A DTC or a Temporary DTC may be set during this procedure. Check for DTCs, and clear them
as needed (see page 11-4). 9. Turn the ignition switch to LOCK (0).
10. Do the battery terminal disconnection procedure (see page 22-68).
11. Remove the quick-connect fitting cover (A).
12. Check the fuel quick-connect fitting for dirt, and clean it if needed.
13. Place a rag or shop towel over the quick-connect fitting (A).

7. Remove the quick-connect fitting cover (A).
8. Check the fuel quick-connect fitting for dirt, and
clean it if needed.
9. Place a rag or shop towel over the quick-connect fitting (A). 10. Disconnect the quick-connect fitting (A): Hold the
connector (B) with one hand, and squeeze the
retainer tabs (C) with the other hand to release
them from the locking tabs (D). Pull the connector
off.
NOTE: Be careful not to damage the line (E) or other parts.
 Do not use tools.
 If the connector does not move, keep the retainer tabs pressed down, and alternately pull and push
the connector until it comes off easily.
 Do not remove the retainer from the line; once removed, the retainer must be replaced with a
new one.
11. After disconnecting the quick-connect fitting, check it for dirt or damage (see step 4 on page 11-330).
12. Do the battery terminal reconnection procedure (see page 22-68).

The fuel line/quick-connect fittings (A), (B), (C), (D), and
(E) connect the fuel rail (F) to fuel feed hose A (G), fuel
feed hose A to fuel feed hose B (H), fuel feed hose B to
the fuel line (I), the fuel line (J) to the fuel tank unit (K),
the fuel vapor line (L) to the EVAP canister (M) and the
fuel tank vapor recirculation tube (N) to the fuel fill pipe
(O). When removing or installing the fuel feed hose, the
fuel tank unit, or the fuel tank, you need to disconnect
or connect the quick-connect fittings.
Pay attention to the following:  The fuel feed hoses, the fuel line, and the quick- connect fittings are not heat-resistant; be careful not
to damage them during welding or other heat-
generating procedures.
 The fuel feed hoses, the fuel line, and the quick- connect fittings are not acid-proof; do not touch them
with a shop towel that was used for wiping battery
electrolyte. Replace them if they come in contact with
electrolyte or something similar.
 When connecting or disconnecting the fuel feed hoses, the fuel line, and the quick-connect fittings, be
careful not to bend or twist them excessively. Replace
them if they are damaged.
A disconnected quick-connect fitting can be
reconnected, but the retainer on the mating line cannot
be reused once it has been removed from the line.
Replace the retainer when: replacing the fuel rail.
 replacing the fuel line.
 replacing the fuel pump.
 replacing the fuel filter.
 replacing the fuel gauge sending unit.
 replacing the EVAP purge line.
 replacing the EVAP canister.
 replacing the fuel tank.
