Never spill engine coolant on drive belts.
NOTE:
When removing only intake manifold, move electric
throttle control actuator without disconnecting the
water hoses.
7. Remove electric throttle control actuator. Loosen mounting bolts in reverse order as shown in the figure.
NOTE:
The figure shows the electric throttle control actuator viewed
from the air duct side.
CAUTION:
Handle carefully to avoid an y impact to electric throttle
control actuator.
Never disassemble.
8. Remove intake manifold, using a power tool. Loosen mounting bolts in reverse order as shown in the figure.
9. Remove intake manifold gaskets. CAUTION:
Cover engine openings to avoid entry of foreign materials.
10. Remove manifold absolute pressure (MAP) sensor, if necessary. CAUTION:
Handle carefully to avoid any impact to manifold absolute pressure (MAP) sensor.
INSTALLATION
Note the following item, and install in the reverse order of removal.

ROCKER COVER
Loosen bolts in reverse order shown in the figure.
8. Remove rocker cover gasket from rocker cover.
9. Use scraper to remove all traces of liquid gasket from cylinder head & VVEL ladder assembly.
CAUTION:
Never scratch or damage the mating su rface when cleaning off old liquid gasket.
10. Remove PCV valve from rocker cover, if necessary.
11. Remove oil filler cap from rocker cover, if necessary.
INSTALLATION
1. Apply liquid gasket with the tube presser (commercial service tool) to VVEL ladder assembly (1).
Use Genuine RTV silicone seal ant or equivalent. Refer to
GI-22, "
Recommended Chemical Products and Sealants".
NOTE:
The figure shows an example of bank 1 side.
Apply liquid gasket on the front and rear side of engine first. [5 mm (0.20 in) + 5 mm (0.20 in) side as shown in the figure]
2. Install rocker cover gasket to rocker cover.
3. Install rocker cover. Check that rocker cover gasket does not drop fr om the installation groove of rocker cover.

4. Tighten bolts in two steps separately in numerical order as
shown in the figure.
Because of the limited working space, use adapter and torquewrench assembly [SST: KV10119300 ( — )] (A) to tighten
bolts (on the No.7 and No. 8 cylinders) to the specified torque.
5. Install ignition coil. Refer to EM-29, "
Exploded View".
CAUTION:
Install Ignition coil marked with an identification mark (A)
on cylinder No. 5, 6, 7 and 8.
