Engine Compression Inspection
1. Warm up the engine to normal operating
temperature (cooling fan comes on).
2. Turn the ignition switch OFF.
3. Remove the intake manifold cover (see step 1 onpage 6-22).
4, Disconnect all four injector connectors.
5. Start the engine, and let it run until it stalls.
6. Remove the iour ignition coils (see page 4-18).
7. Remove the four spark plugs.
8. Attach the compression gauge to the spark plug
note.

10.
Open the throttle fully, then crank the engine with
the starter motor and measure the compression.
Compression Pressure
Above 930 kpa (9.5 kgf/cm', 135 psi)
Measure the compression on the remaining
cylinders,
Maximum vadation
Within 200 kPa (2.0 kgf/cm', 28 psi)
lf the compression is not within specifications,
check these items, then remeasure the
compressron.

Cylinder Head
Valve Guide Replacement (cont'dl
Apply a thin coat of clean engine oil to the outside
of the new valve guide. Install the guide from the
camshaft side of the head; use the special tool to
drive the guide in to the specified installed height
(A) o{the guide (B). lf you have all 16 guidesto do,
you may have to reheat the head.
Valve Guide Installed Height:
Intake: 15.2 16.2 mm (0.598-0.638 in.)
Exhaust: 15.5 16.5 mm (0.610-0.650 in.)

\
10.Coat both reamer and valve guide with cutting oil.
Rotate the reamer clockwise the full length of the
valve guide bore.
O7HAH.PJ7O1OB
Continue to rotate the reamer clockwise while
removing it from the bore.
Thoroughly wash the guide in detergent and water
to remove any cutting residue.
Check the clearances with a valve (see page 6 32).
Verify that a valve slides in the intake and exhaust
valve guides without exening pressure.

Oil Pressure Switch Test
1. Remove the YEURED wire (A)from the engine oilpressure switch (B).
Check for continuity between the positive terminal(C) and the engine (ground). There should be
continuity with the engine stopped. There should
be no continuity with the engine running.
lf the switch fails to operate, check the engine oil
level. lf the engine oil level is OK. check the engine
oil pressure. lf the oil pressure is OK, replace lhe oil
Dressure switch.

Oil Pressure Test
lf the oil pressure indicator stays on with the engine
running. check the engine oil level. lf the oil level is
correct:
Connect a tachometer.
Remove the engine oil pressure switch, and install
an oil pressure gauge {A).
{
'1.
\.(
4.
Sta rt the engine. Shut it off immediately if thegauge registers no oil pressure. Repair lhe problem
before continuing.
Allow the engine to reach operating temperature(fan comes on at least twice), The pressure should
be:
Engine Oil Temperature: 176'F (80'Cl
Engine Oil Pressure:
At ldle:70 kPa (0.7 kgf/cm', 10 psi)
mtntmum
At 3,000 rpm: 300 kPa (3.1 kgf/cm',44 psi)
minimum
lf the oil pressure is NOT within specifications,
inspect these items:. Check the oil screenforclogging.. Check the oil pump (see page 8-8).. Check crankshaft and connecting rod bearing
clearances.
