EXHAUST MANIFOLD AND TURBOCHARGER ASSEMBLY
1. Refer to the figure and install the gasket (1) to the cylinder head
(2).
2. Tighten nuts in the numerical order shown in the figure.
CAUTION:
Nuts 1, 4 - 8 do not have washers. Because 2 and 3 are nuts
with washers, be careful of the installation positions.
NOTE:
Nuts 9 - 12 indicate the second tightening.
3. Install removed parts in the reverse order of removal.
CAUTION:
After the exhaust manifold and turbocharger assembly is replaced, perform fully-closed position
learning for the wastegate valve, and use CONSULT to individually check the functions of the tur-
bocharger system. Refer to
(fully-closed position learning for waste
gate valve) and
EC-932, "Component Function Check"
(individual function inspection).
Inspection
INFOID:0000000012197427
INSPECTION PROCEDURE
Turbocharger Trouble Diagnosis [Oil Leakage, Smoke (white/blue), Lack of Power, Poor Acceleration, Unusual
Noise]
Check items before trouble diagnosis
1. Check that the engine oil amount is the specified level.
2. Interview the customer about whether the engine oil is cooled down by idling after driving.
Diagnosis
• Refer to the table below and check each of the parts.
• For the inspection methods, refer to "INSPECTION AFTER REMOVAL."

INSPECTION AFTER REMOVAL
Perform the following checks. If any adhering material is found, perform cleaning. If any irregularities are
found, or if the value is outside the standard, replace the exhaust manifold and turbocharger assembly.
• Refer to the figure for the names of parts and the locations for visual inspection.
• If the compressor wheel, turbine wheel, rotor shaft, or other internal part is damaged, check the following
paths and completely remove all fragments and other foreign material for preventing secondary malfunc-
tions.
Cleaning Work
NOTE:
The following explanatory figure shows an image of the inspection procedure. (The shapes in the figure do not
match the actual vehicle parts.)
• Clean before checking.
- Use engine conditioner (A) to clean the oil feed and return ports.
- Use radiator cleaner to clean the water feed and return ports.
• After cleaning, air-blow using an air gun (A).
• Air-blow the compressor wheel, turbine wheel, compressor hous-
ing, and turbine housing.
Compressor wheel
Inside of intake port is badly stained with
oil.
There are marks from rubbing against
housing.
Vane is bent or broken.
Rotor shaft
Heavy feel or catching when turned by
hand.
Cannot be turned by hand.
Excessively loose bearing.
Oil return port
Carbon or sludge deposit in oil drain port.

EXHAUST MANIFOLD AND TURBOCHARGER ASSEMBLY
Turbine Wheel and Compressor Wheel
• Check visually, and by other means, for adhering oil.
• Check visually, and by other means, for adhering carbon.
• Check for bent or broken vanes.
• Check for interference with the housing.
Rotor Shaft
• Rotate rotor shaft (A) by hand and check that it turns smoothly
without resistance or sticking.
• Shake rotor shaft (A) vertically and horizontally and check for
looseness.
Mounting Surface Distortion
• Using a thickness gauge (A) and straightedge (B), check for distor-
tion of the exhaust manifold and turbocharger assembly mounting
surface at each port, and for distortion of the overall assembly.
• Replace exhaust manifold and turbocharger assembly if the limit is
exceeded.
INSPECTION AFTER INSTALLATION
Start the engine and increase the engine speed. Check for engine oil leakage, exhaust gas leakage, and cool-
ant leakage.
