GENERAL INFORMATION
FORM-IN-PLACE GASKETS
There are numerous places where form-in-place
gaskets are used on the engine. Care must be taken
when applying form-in-place gaskets to assure
obtaining the desired results. Do not use form-in-
place gasket material unless specified. Bead size,
continuity, and location are of great importance. Too
thin a bead can result in leakage while too much can
result in spill-over which can break off and obstruct
fluid feed lines. A continuous bead of the proper
width is essential to obtain a leak-free gasket.
There are numerous types of form-in-place gasket
materials that are used in the engine area. Mopar
Silicone Rubber Adhesive Sealant and Mopar Gasket
Maker gasket materials, each have different proper-
ties and can not be used in place of the other.
MOPAR SILICONE
SEALANT
Mopar Silicone Rubber Adhesive Sealant or equiv-
alent, normally black in color, is available in three
ounce tubes. Moisture in the air causes the Mopar
Silicone Rubber Adhesive Sealant material to cure.
This material is normally used on flexible metal
flanges. It has a shelf life of one year and will not
properly cure if over age. Always inspect the package
for the expiration date before use.

MOPAR GASKET MAKER
Mopar Gasket Maker is an anaerobic type gasket
material. The material cures in the absence of air
when squeezed between two metallic surfaces. It will
not cure if left in the uncovered tube. The anaerobic
material is for use between two machined surfaces.
Do not use on flexible metal flanges.
MOPAR TORQUE CURE GASKET MAKER
Mopar Torque Cure Gasket Maker is a unique
anaerobic type gasket material to be used ONLY
between the bedplate and engine block. The material
cures in the absence of air when torqued between
two metallic surfaces. It will not cure if left in the
uncovered tube. This anaerobic material is specially
made to seal the area between the bedplate and cyl-
inder block without disturbing the bearing clearance
or alignment of these components.
GASKET DISASSEMBLY
Parts assembled with form-in-place gaskets may be
disassembled without
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.
SURFACE PREPARATION
Scrape clean or wire brush all gasket surfaces
removing all loose material. Inspect stamped parts to
