NOTE: *: Part to be sealed with a form-in-place
gasket (FIPG)
FORM-IN-PLACE GASKET (FIPG)
This engine has several areas where the
form-in-place gasket (FIPG) is used for sealing. To
ensure that the FIPG fully serves its purpose, it is
necessary to observe some precautions when
applying it.
Bead size, continuity and location are of paramount
importance. Too thin a bead could cause leaks. Too
thick a bead, on the other hand, could be squeezed
out of location, causing blocking or narrowing of fluid
passages. To prevent leaks or blocking of passages,
therefore, it is absolutely necessary to apply the
FIPG evenly without a break, while observing the
correct bead size.
FIPG hardens as it reacts with the moisture in the
atmospheric air, and it is usually used for sealing
metallic flange areas.
REMOVAL OF FIPG SEALED PARTS
Parts sealed with a FIPG can be easily removed
without need for the use of a special method. In
some cases, however, the FIPG in joints may have to
be broken by tapping parts with a mallet or similar
tool. You can also tap a flat, thin gasket scraper into
the joint to break the FIPG, taking extreme care not
to damage the mating surfaces.The oil pan cutter
(MD998727) is available as a special tool for
removing the oil pan. The tool, however, must not be.
CLEANING FIPG APPLICATION
SURFACE
Thoroughly remove all substances deposited on the
FIPG application surface, using a gasket scraper or
wire brush. Make sure that the FIPG application
surface is flat and smooth. Also make sure that the
surface is free from oils, greases and foreign
substances. Do not fail to remove old FIPG that may
remain in the fastener fitting holes.
APPLICATION OF FIPG
Applied FIPG bead should be of the specified size
and free of any break. FIPG can be wiped away
unless it has completely hardened. Install the mating
parts in position while the FIPG is still wet (in less
than 15 minutes after application). Do not allow FIPG
to spread beyond the sealing areas during
installation. Avoid operating the engine or letting oils
or water come in contact with the sealed area before
a time sufficient for FIPG to harden (approximately
one hour) has passed. FIPG application method may
vary from location to location. Follow the instruction
for each particular case described later in this
manual.
