8. Install new front oil seal to front cover. Refer to
EM-71, "Removal and Installation of Front Oil Seal".
9. Install front cover with the following procedure:
a. Install O-rings to cylinder head and cylinder block. CAUTION:
Do not reuse O-rings.
b. Apply a continuous bead of liquid gasket to front cover as shown.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-21, "Recommended Chemi cal Products and Sealants"
.
CAUTION:
• For bolt holes with marks (5 locations), apply liquid
gasket outside the holes.
• Installation should be done within 5 minutes after applica-
tion of liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after
the components are installed to allow the liquid gasket to
cure.
c. Make sure the mating marks on the timing chain and each sprocket are still aligned. Then install the front cover.
CAUTION:
Do not damage the front oi l seal during installation.

9. Remove the chain tension guide.
INSPECTION
Check for cracks and any excessive
wear of the timing chain. Replace the timing chain as necessary.
INSTALLATION
NOTE:
The illustration shows the relationship between the mating mark on each timing chain and that on the corre-
sponding sprocket, the components installed.
1. Install the timing chain tension guide.
2. Check that dowel pin (A) and crankshaft key (1) are located as shown. (No. 1 cylinder at compression TDC)
NOTE:
Though camshaft does not stop at the position as shown, for the
placement of cam nose, it is generally accepted camshaft is
placed in the same direction.

CAMSHAFT
1. Before installation, remove any old Silicone RTV Sealant from
component mating surfaces using a scraper.
• Remove the old Silicone RTV Sealant from the bolt holes and
threads.
• Do not scratch or damage the mating surfaces.
2. Before installing the front cam bracket, remove the old Silicone RTV Sealant from the mating surface using a scraper.
• Do not scratch or damage the mating surface.
3. Turn the crankshaft until No. 1 piston is set at TDC on the com- pression stroke.
• The crankshaft key should line up with the right bank cylinder
center line as shown.
4. Install camshaft chain tensioners on both sides of cylinder head. Refer to EM-182, "Removal and Installation"
.
CAUTION:
Do not reuse O-rings.
5. Install valve lifters, if removed. NOTE:
Install them in original positions.

7. Remove cylinder heads and gaskets.
• Discard the cylinder head gaskets and use new gaskets forinstallation.
INSTALLATION
1. Turn the crankshaft until No. 1 piston is set at TDC on the com- pression stroke.
• The crankshaft key should line up with the right bank cylinder
center line as shown.
2. Install new gaskets on the cylinder heads.
3. Inspect the cylinder head bolts before installing the cylinder heads. CAUTION:
Cylinder head bolts are tighte ned by degree rotation tight-
ening method. Whenever the size difference between d1
and d2 exceeds the limit, replace the bolts with new ones.
• Lubricate threads and seat surfaces of the bolts with new
engine oil.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.
