NEW TIGHTENING METHOD – BY USE OF BOLTS TO BE TIGHTENED IN
PLASTIC AREA
A new type of bolts, to be tightened in plastic area, is currently used some parts of the engine. The
tightening method for the bolts is different from the conventional one. Be sure to observe the method
described in the text when tightening the bolts.
Service limits are provided for the bolts. Make sure that the service limits described in the text are strictly
observed.

Areas where the bolts are in use:
(1) Cylinder head bolts
(2) Main bearing cap bolts
(3) Connecting rod cap bolts

Tightening method
After tightening the bolts to the specified torque, tighten them another 90° or 180° (twice 90°). The
tightening method varies on different areas. Observe the tightening method described in the text.

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 possibility 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 vulcanisation (RTV) type and is supplied in a 100-gram
tube (Part No. MD970389). Since the RTV hardens as it reacts with the moisture in the atmospheric
air, it is normally used in the metallic flange areas. The FIPG, Part No. MD970389, can be used for
sealing both engine oil and coolant, while Part No. MD997110 can only be used for engine oil sealing.
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” (MD998727) 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 application procedure may vary on different areas. Observe the procedure described in the
text when applying the FIPG.
