FORM-IN-PLACE GASKETS—GASOLINE ENGINES
There are several places where form-in-place gas­
kets are used on the engine. DO NOT use form-in-
place gasket material unless specified. Care
must be taken when applying form-in-place gaskets.
Bead size, continuity, and location are of great impor­
tance. Too-thin a bead can result in leakage, while
too much can result in spill-over. A continuous bead
of the proper width is essential to obtain a leak-free
joint.
Two types of form-in-place gasket materials are
used i n the engine area (Mopar® Silicone Rubber
Adhesive Sealant and Mopar® Gasket Maker). Each
has different properties and they cannot be used
interchangeably.
MOPAR® SILICONE RUBBER ADHESIVE
SEALANT
Mopar® Silicone Rubber Adhesive Sealant, nor­
mally black in color, is available in both three ounce
tubes and four and one-half ounce power tubes. Mois­
ture i n the air causes the sealant material to cure.
This material is normally used on flexible metal
flanges. The tubes have a shelf life of one year and
the power tubes two years shelf life, and will not

age for the expiration date before use.
MOPAR® GASKET MAKER
Mopar® Gasket Maker, normally red in color, is
available in six-cc tubes. This anaerobic type gasket
material cures in the absence of air when squeezed
between smooth machined metallic surfaces.' I t will
not cure i f left in the uncovered tube. DO NOT use
on flexible metal flanges.
SURFACE PREPARATION
Parts assembled with form-in-place gaskets may be
disassembled without unusual effort. In some
instances, 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 into the joint, but care
must be taken not to damage the mating surfaces.
Scrape or wire brush all gasket surfaces to remove
all loose material. Inspect stamped parts to ensure
that gasket rails are flat. Flatten rails with a ham­
mer on a flat plate, i f required. Gasket surfaces must •
be free of oil and dirt. Be sure the old gasket mate­
rial is removed from blind attaching holes.
