2. Apply liquid gasket to the block mating surfaces of
the oil pan, then install it. Apply liquid gasket to the
shaded areas.
NOTEI
. Use liquid gasket part No. 087 18 - 0001 or
08718 - 0003.
. Check that the mating surfaces are clean and dry
before apPlying liquid gasket.
. Apply liquid gasket as an even bead, centered
between the edges ol the mating surface'
. To prevent leakage of oil, apply liquid gasket to
the inner threads of the bolt holes
. Do not install the parts if five minutes or more
have elapsed since applying the liquid gasket
lnstead, reapply liquid gasket after removing the
old residue
. After assembly, wait at least 30 minutes before
filling the engine with oil.

Oil Seals
lnstallation
NOTE:
. Engine removal is not required.
. The crankshaft oil seal housing should be dry.
Apply a light coat of grease to the crankshaft and to
the lips of the seals.
1. Using the special tool, drive in the timing pulley-
end seal until the driver bottoms against the oil
pump.
When the seal is in place, clean any excess grease
off the crankshaft and check that the oil seal lip is
not distorted.

2. Measure the flvwheel-end seal thickness and the oil
seal housing depth. Using the special tool. drive the
flywheel-end seal into the rear cover to the point
where the clearance between the bottom of the oil
seal and the right side cover is 0.5 - 0.8 mm (0.02 -
0.03 in) (see page 7-23).
NOTE: Align the hole in the driver attachment with
the Din on the crankshaft.

The numbers in the middle of the API Service label tell
you the oil's SAE viscosity or weight Select the oil for
vour car according to this chart:
30 20 -10 010 20 30 4OoC
An oil with a viscosity of 5W - 30 is preferred for
improved tuel economy and year-round protection in the
car. You may use a 10W - 30 oil if the climate in your area
is limited to the temperature range shown on the chart'

Use this procedure to tighten the filter if eight num-
bers (1 to 8) are printed on the surface of the filter.
1) Make a mark on the oil filter base under the num-
ber that shows at the bottom of the filter when
the rubber seal is seated.
2l Tighten the filter by turning it clockwise seven
numbers from the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point'

ified level, run the engine for more than three minutes,
then check for oil leakage

Testing
lf the oil pressure warning Iight stays on with the engine
running, check the engine oil level. It the oil level is cor-
rect:
1. Connect a tachometer'
2. Remove the engine oil pressure switch, and install an
oal pressure gauge.

{CommerciallY availablei
Start the engine. Shut it off immediately if the gauge
registers no oil pr€ssure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (tan
comes on at least tlivice). The pressure should be;
Engine Oil Temperature: 176"F (80"C1
Engine Oil Pressulo:
At ldle: 69 kPa (0.7 kgf/Gm'. 10 Psi)

. lf the oil Dressure is within specifications, replace
the oil pressure switch and recheck.
. lf the oil pressure is NOT within specifications,
inspect the oil pump (see page 8-10).

Inspection
1.Remove the oil jet (see page 8-3) and inspect it asfollows.
Make sure that a 1.1 mm (0.04 in) diameter drillwill go through the nozzte hole (j.2 mm (0.05 in)diameter).
Insert the other end of the same 1.1 mm (0.04 in)drill into rhe oil intake (i.2 mm (0.05 in) diame_ter).
Make sure the check ball moves smoothly andhas a stroke of approximately 4.0 mm (0.16 in).Check the oil jet operation with an air nozzle. ltshould take at least 200 kPa (2.0 kgf/cm,, 28 psi)to unseat the check ball.
NOTE: Replace the oil jet assembly if the nozzlers damaged or bent.

20. Install the two dowel pins and new O-ring on the oilpump.
21. Apply liquid gasket to the cylinder block mating sur_face of the oil pump.
NOTE:
. Use liquid gasket, Part No.08718 - oOOj or 08718- 0003.. Check that the mating surfaces are clean and drybefore applying liquid gaskel. Apply liquid gasket evenly, in a narrow bead cen-tered on the mating surface.o To prevent leakage of oil, apply liquid gasket tothe inner threads of the bolt holes.. Do not install the parts if five mtnures or morehave elapsed since applying liquid gasket.Instead. reapply liquid gasket after removing theold residue.
