FORM-IN-PLACE GASKETS
There are numerous places where form-in-place gaskets are used on the engine. Care must be
when applying form-in-place gaskets to assure obtaining the desired results. size, continuity, ‘and
location are of great importance. Too thin a bead can result in leakage
too much can result’ in
spill-over which can break off and obstruct fluid f eed lines.
A continuous bead of the proper width
essential to obtain a leak-free joint.
GASKET DISASSEMBLY
Parts assembled with form-in-place gaskets may be d isassembled without unusual effort’
it may be necessary to lightly tap the part with a mallet or other suitable tool to break the seal between
the mating surfaces.A flat gasket scraper may also be lightly tapped in to the joint but care be
taken not to damage the mating surfaces.
SURFACE PREPARATION
Scrape clean or wire brush all gasketsurfaces removing all loose material. Inspect
assure gasket rails are flat.
Flatten rails with a hammer on a flat plate if
must be free of oil and dirt. Make sure old gasket material is removed from blind
FORM-IN-PLACE GASKET APPLICATION
Assembling parts using a form-in-place gasket requires care but it’s easier than using precut gaskets.
Gasket material should be applied sparingly 1 mm
inch.) diameter or less to one
surface, Be certain the material surrounds each mou nting hole.
Excess material can easily be
‘off. Components should be torqued in place within 15 minutes. The use of a locating dowel is recommen ded
during assembly, to prevent smearing the material off location.
Loctite 18718 gasket material or equivalent should be applied in a continuous bead

For corner sealing, 3.17 or 6.35

be removed with a shop towels. Components should be torqued in place while the sea lant

to the touch (within 10 minutes). The usage of a locating dowel is recommended during assembly to
prevent smearing of material off location.
MOPAR TORQUE CURE GASKET MAKER
Mopar torque cure gasket maker is a unique anaerobi c type gasket material to be used ONLY
the and engine block. The material cures in the absenc e of air when. two
metallic surfaces. It will not cure if left in the uncovered tube. This anaerobic material
specially made
to seal the area between the
and cylinder block without disturbing the bearing’ or
alignment of these components.. .
