INSPECTION AFTER REMOVAL
Surface Distortion

Using straightedge and feeler gauge, check the surface distor-
tion of exhaust manifold and three way catalyst assembly mating
surface.

If it exceeds the limit, replace exhaust manifold and three way
catalyst assembly.

CAUTION:

Before installing a new heated oxygen sensor, clean exhaust system threads using heated oxygen
sensor thread cleaner (commercial service tool) and apply anti-seize lubricant (commercial ser-
vice tool).

Do not exceed the specified torque heated oxygen sensor. Doing so may cause damage to heated
oxygen sensor, resulting in the “MIL” coming on.

Refer to GI-10, "Components" for symbol marks in the figure.
NOTE:
This section describes removal/installation procedure of camshaft without removing front cover. If front cover
is removed or installed, removal of camshaft bracket (No. 1) is easier before step 9 and installation is easier
after step 3. Regarding removal and installation of front cover, refer to EM-53, "
TIMING CHAIN" .
REMOVAL
1. Release fuel pressure. Refer to EC-49, "FUEL PRESSURE RELEASE" .
2. Remove the following parts.

b. Push in chain tensioner plunger. Insert a stopper pin into hole on
chain tensioner body to secure chain tensioner plunger and
remove chain tensioner.
CAUTION:
Be careful not to drop mounting bolts inside front cover.
NOTE:
Use approximately 0.5 mm (0.02 in) dia. hard metal pin as a
stopper pin.
c. Secure hexagonal part of camshaft with wrench. Loosen cam-
shaft sprocket mounting bolts and remove camshaft sprockets.
CAUTION:

Do not loosen mounting bolts with securing anything
other than the camshaft hexagonal part or with tension-
ing timing chain.

Do not rotate crankshaft or camshaft while timing chain
is removed. It causes interference between valve and pis-
ton.
NOTE:
Chain tension holding work is not necessary. Crankshaft
sprocket and timing chain do not disconnect structurally while
front cover is attached.
9. Remove camshaft position sensor (PHASE) from cylinder head back side.
CAUTION:

Handle carefully to avoid dropping and shocks.

Do not disassemble.

Do not allow metal powder to adhere to magnetic part at sensor tip.

Do not place sensor in a location where it is exposed to magnetism.
10. Loosen mounting bolts in reverse order as shown in the figure,
and remove camshaft brackets.

Remove camshaft bracket (No. 1) by slightly tapping it with
plastic hammer.
11. Remove camshafts.
12. Remove valve lifters.

Identify installation positions, and store them without mixing them up.

INSTALLATION
1. Install valve lifters.

Install them in the original positions.
2. Install camshafts.

Distinction between intake and exhaust camshafts is per-
formed with the different shapes of rear end.

Install camshafts so that camshaft dowel pins on the front side
are positioned as shown in the figure.
3. Install camshaft brackets with the following procedure.
CAUTION:
Completely remove any foreign material on back surface of camshaft brackets and top surface of
cylinder head.
a. Install camshaft brackets (No. 2 to 5) aligning the identification
marks on upper surface as shown in the figure.
NOTE:
Install so that identification mark can be correctly read when
viewed from the exhaust side.
b. Install camshaft bracket (No. 1) with the following procedure:
i. Apply liquid gasket to camshaft bracket (No. 1) as shown in the
figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
After installation, be sure to wipe off any excessive liquid
gasket leaking from part “A”.Intake : Signal plate shape for camshaft position
sensor (PHASE)
Exhaust : Cone end shape

Apply liquid gasket to the outside of bolt hole on front cover.
iii. For camshaft bracket (No. 1) near installation position, and
install it without disturbing the liquid gasket applied to the sur-
faces.
4. Tighten mounting bolts of camshaft brackets in the following
steps, in numerical order as shown in the figure.
a. Tighten No. 9 to 11 in numerical order.
b. Tighten No. 1 to 8 in numerical order.
c. Tighten all bolts in numerical order.
d. Tighten all bolts in numerical order.
CAUTION:
After tightening mounting bolts of camshaft brackets, be sure to wipe off excessive liquid gasket
from the parts listed below.

Mating surfaces of rocker cover.

Mating surface of front cover. (When installed without front cover)
5. Install camshaft position sensor (PHASE).
6. Install camshaft sprockets.

Install them by aligning the mating marks on each camshaft
sprocket with the paint marks on timing chain link plate during
removal.
CAUTION:

Aligned mating marks could slip. Therefore, after
matching them, hold the timing chain in place by hand.

Before and after installing chain tensioner, make sure
again that mating marks have not slipped.
NOTE:
Before installation of chain tensioner, it is possible to re-match
the marks on timing chain with the ones on each sprocket.
