6. Using compound, perform valve fitting.
7. Check again to make sure that contacting status is satisfactory.
For details, Refer to EM-205, "
Valve Seat Contact" .
8. Use the depth gauge to measure the distance between the
mounting surface of cylinder head spring seat and the valve
stem end. If the distance is shorter than specified, repeat step 5
above to adjust it. If it is longer, replace valve seat with a new
one.
Valve Spring Square

Position the try square to valve spring, turn the spring, and mea-
sure the maximum clearance value between top surface of
spring and the try square.

If it exceeds the limit, replace valve spring.
Valve Spring Dimensions and Valve Spring Pressure Load

Using valve spring tester, check the following.

If out of the standard, replace the valve spring.Valve seat resurface limit “L”:

MAIN BEARING OIL CLEARANCE
Method by Measurement

Install main bearings to cylinder block and bearing cap, and
tighten the bolts to the specified torque. Refer to EM-217,
"ASSEMBLY" . Then, measure the inner diameter of main bear-
ings.
(Bearing clearance) = (Bearing inner diameter) − (Crankshaft
journal outer diameter)

If out of the standard, check main bearing housing inner diame-
ter and crankshaft journal outer diameter, and select appropriate
main bearing to adjust clearance to specifications. Refer to EM-
224, "HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove contamination such as engine oil and dust completely
from crankshaft journals and each bearing surface.

Cut plastigage slightly shorter than bearing width. Place it in
crankshaft turning direction, avoiding oil holes.

Install main bearings and bearing cap and tighten to the speci-
fied torque. Refer to EM-217, "
ASSEMBLY" for the tightening
procedure.
CAUTION:
Do not rotate crankshaft.

Remove main bearings and bearing caps, and measure plasti-
gage width using scale on plastigage bag.
NOTE:
If out of specification, take same action mentioned in “Method by Measurement”.
CRUSH HEIGHT OF MAIN BEARING

When bearing cap is removed after being tightened to the speci-
fied torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-217, "
ASSEMBLY" .

If out of the standard, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING

When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-217,
"ASSEMBLY" .

If out of the standard, replace connecting rod bearings.Standard : 0.039 - 0.066 mm (0.0015 - 0.0026 in)

INSPECTION
1. Apply pressure with radiator cap tester adapter (special service
tool) and radiator cap tester (commercial service tool).
WARNING:
To prevent the risk of hose coming undone while under
pressure, securely fasten it down with hose clamp.
CAUTION:
Attach hose to A/T fluid cooler to seal its inlet and outlet.
(A/T models)
2. Check for leakage by soaking radiator in water container with
the testing pressure applied.Standard height “H” : 8.0 - 8.4 mm (0.315 - 0.331 in)

1. Check resistance between HO2S1 terminals as follows.
2. If NG, replace heated oxygen sensor 1.
CAUTION:

Discard any heated oxygen sensor which has been dropped
from a height of more than 0.5 m (19.7 in) onto a hard sur-
face such as a concrete floor; use a new one.

Before installing new oxygen sensor, clean exhaust system
threads using Oxygen Sensor Thread Cleaner tool J-43897-
