FORM-IN-PLACE GASKET
The engine has several areas where the form-in-place gasket (FIPG) is in use. To ensure that the gasket
fully serves its purpose, it is necessary to observe some precautions when applying the gasket. 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 the
fluid feed line. To eliminate the possibly of leaks from a joint, therefore, it is absolutely necessary to
apply the gasket evenly without a break, while observing the correct bead size.
The FIPG used in the engine is a room temperature vulcanization (RTV) type. Since the RTV hardens
as it reacts with the moisture in the atmospheric air, it is normally used in the metallic flange areas.
Disassembly
The parts assembled with the FIPG can be easily disassembled without use of a special method. In
some cases, however, the sealant between the joined surfaces may have to be broken by lightly striking
with a mallet or similar tool. A flat and thin gasket scraper may be lightly hammered in between the
joined surfaces. In this case, however, care must be taken to prevent damage to the joined surfaces.
For removal of the oil pan, the special tool “Oil Pan Remover” is available. Be sure to use the special
tool to remove the oil pan.
Surface Preparation
Thoroughly remove all substances deposited on the gasket application surfaces, using a gasket scraper
or wire brush. Check to ensure that the surfaces to which the FIPG is to be applied is flat. Make sure
that there are no oils, greases and foreign substances deposited on the application surfaces. Do not
forget to remove the old sealant remained in the bolt holes.
Form-In-Place Gasket Application
When assembling parts with the FIPG, you must observe some precautions, but the procedures is very
simple as in the case of a conventional precut gasket.
Applied FIPG bead should be of the specified size and without breaks. Also be sure to encircle the
bolt hole circumference with a completely continuous bead. The FIPG can be wiped away unless it is
hardened. While the FIPG is still moist (in less than 15 minutes), mount the parts in position. When
the parts are mounted, make sure that the gasket is applied to the required area only. In addition, do
not apply any oil or water to the sealing locations or start the engine until a sufficient amount of time
(about one hour) has passed after installation is completed.
The FIPG applications procedure may vary on different areas. Observe the procedure described in the
text when applying the FIPG.

(1) Connect the nozzle tester to injection nozzle 3 and carry
out the tests described below.
Caution
D
Before starting the tests, operate the lever of the
nozzle tester two or three times to bleed air from
the nozzle.
Valve opening pressure test
(1) Slowly push down the nozzle tester lever. The pressure
gauge pointer will gradually rise and then deflect suddenly
at a certain value. Make a note of the pressure at which
the pointer suddenly deflects.
(2) If this pressure value deviates from the standard value,
disassemble the nozzle. Clean and reassemble the
nozzle. Then adjust to the specified pressure by fitting
a different shim 9.
(3) A difference in shim thickness of 0.05 mm changes the
opening pressure by 5 kPa. Shims are available in
thicknesses from 1.00 to 1.95 mm, increasing by
increments of 0.05 mm.
(4) Fit a new fuel injection nozzle 3 if the pressure value
is still incorrect after adjustment.

Spray pattern test
(1) Move the nozzle tester lever with a fast short stroke (four
to six strokes per second) so that a continuous spray
of fuel is obtained from the nozzle.

(correct).
B: Excessive spray angle (incorrect).
C: Spray deflected to one side (incorrect).
D: Interrupted spray form (incorrect).
