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.

Inspection
1.Park the vehicle on level ground, and turn off theengine. Allow the oil a few minutes to drain backinto the oil pan so the dipstick will show the actuallevel.
Make certain that the oil level indicated on the dip_stick is between the upper and lower marks.
lf the level has dropped close to the lower mark.add oil until it reaches the upper mark.
CAUTION: lmert thc dipstick car€fully to avoid b€nd_ing it.

17. Reassemble the oil pump, applying thread lock tothe pump housing screws.
18. Check that the oil pump turns freely.
19. Apply a light coat of oilto the seal lip.
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.
. After assembly, wait at least 30 minutes beforefilling the engine with oil.
