vent corrosion. MopartGasket Sealant is available in
a 13 oz. aerosol can or 4oz./16 oz. can w/applicator.
FORM-IN-PLACE GASKET AND SEALER
APPLICATION
Assembling parts using a form-in-place gasket
requires care but it's easier then using precut gas-
kets.
MopartGasket Maker material should be applied
sparingly 1 mm (0.040 in.) diameter or less of sealant
to one gasket surface. Be certain the material sur-
rounds each mounting hole. Excess material can eas-
ily be wiped off. Components should be torqued in
place within 15 minutes. The use of a locating dowel
is recommended during assembly to prevent smear-
ing material off the location.
MopartEngine RTV GEN II or ATF RTV gasket
material should be applied in a continuous bead
approximately 3 mm (0.120 in.) in diameter. All
mounting holes must be circled. For corner sealing, a
3.17 or 6.35 mm (1/8 or 1/4 in.) drop is placed in the
center of the gasket contact area. Uncured sealant
may be removed with a shop towel. Components
should be torqued in place while the sealant is still
wet to the touch (within 10 minutes). The usage of a
locating dowel is recommended during assembly to
prevent smearing material off the location.
MopartGasket Sealant in an aerosol can should be
applied using a thin, even coat sprayed completely
over both surfaces to be joined, and both sides of a
gasket. Then proceed with assembly. Material in a
can w/applicator can be brushed on evenly over the
sealing surfaces. Material in an aerosol can should be
used on engines with multi-layer steel gaskets.
STANDARD PROCEDUREÐREPAIR DAMAGED
OR WORN THREADS
CAUTION: Be sure that the tapped holes maintain
the original center line.
Damaged or worn threads can be repaired. Essen-
tially, this repair consists of:
²Drilling out worn or damaged threads.
²Tapping the hole with a special Heli-Coil Tap, or
equivalent.
²Installing an insert into the tapped hole to bring
the hole back to its original thread size.
STANDARD PROCEDUREÐHYDROSTATIC

(11) Check the bore cleanliness by wiping with a
white, lint free, lightly oiled cloth. If grit residue is
still present, repeat the cleaning process until all res-
idue is removed. Wash the bores and the complete
block assembly with solvent and dry with compressed

STANDARD PROCEDUREÐCYLINDER BORE
REPAIR
Cylinder bore(s) can be repaired by one of two
methods:
²Method 1:ÐOver boring and using oversize pis-
tons and rings.
²Method 2:ÐBoring and installing a repair sleeve
to return the bore to standard dimensions.
METHOD 1ÐOVERSIZE BORE
Cylinder bore(s) can be repaired by one of two
methods:
Oversize pistons and rings are available in two
sizes - 0.50 mm (0.0197 inch) and 1.00 mm (0.0393
inch).
Any combination of standard, 0.50 mm (0.0197
inch) or 1.00 mm (0.0393 inch) overbore may be used
in the same engine.
If more than 1.00 mm (0.0393 inch) overbore is
needed, a repair sleeve can be installed (refer to
Method 2ÐRepair Sleeve).
Cylinder block bores may be bored twice before use
of a repair sleeve is required (Fig. 72). The first bore
is 0.50 mm (0.0197 inch) oversize. The second bore is
1.00 mm (0.0393 inch) oversize.
After boring to size, use a honing stone to chamfer
the edge of the bore (Fig. 72).

A correctly honed surface will have a crosshatch
appearance with the lines at 15É to 25É angles with
the top of the cylinder block (Fig. 73). For the rough
hone, use 80 grit honing stones. To finish hone, use
280 grit honing stones.
A maximum of 1.2 micrometer (48 microinch) sur-
face finish must be obtained.
After finish honing is complete, immediately clean
the cylinder bores with a strong solution of laundry
detergent and hot water.
After rinsing, blow the block dry.
Check the bore cleanliness by wiping with a white,
lint-free, lightly- oiled cloth. There should be no grit
residue present.
If the block is not to be used right away, coat it
with a rust- preventing compound.
METHOD 2ÐREPAIR SLEEVE
If more than a 1.00 mm (0.03937 inch) diameter
oversize bore is required, the block must be bored
and a repair sleeve installed.
Bore the block cylinder bore to 104.500-104.515
