INTAKE AND EXHAUST – Exhaust Manifold and Turbocharger15-13
COIL RETURN PIPE GASKET INSTALLATION
Install the gasket so that its print part is on the oil pan side.
INSPECTION
1. TURBOCHARGER CHECK
(1) Visually check the turbine wheel and compressor wheel
for damage and cracking.
(2) Check that the turbine wheel and compressor wheel can
be turned manually with a light force.
(3) Check that there is no oil leak from the turbocharger.
(4) Check to see if the wastegate valve remains open. If
any of these faulty symptoms is evident, disassemble
the turbocharger and replace the defective part.
NOTE
For the disassembly procedure, refer to ENGINE
WORKSHOP MANUAL.
2. EXHAUST MANIFOLD CHECK
(1) Check the exhaust manifold for damage and cracking
and replace it as necessary.
(2) Using a straightedge and feeler gauge, check the cylinder
head mounting surface for distortion and replace as
necessary.

FORM-IN-PLACE GASKET
The transmission 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.
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.
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 remaining in the bolt holes.
FORM-IN-PLACE GASKET APPLICATION
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 10 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.
