8. Remove exhaust manifold. • Loosen nuts in the reverse of the order shown.
9. Remove gasket. CAUTION:
Cover engine openings to avoid entry of foreign materials.
10. Remove exhaust manifold cover from back of exhaust manifold.
INSPECTION AFTER REMOVAL
Mounting Surface Distortion
• Use suitable tools (A) and (B) to check distortion of exhaust mani- fold mounting surface as shown.
• Replace exhaust manifold if outside the limit.

EXHAUST MANIFOLD
1. Tighten exhaust manifold nuts to specification in two stages in
the numerical order shown.
2. Use Tool (A) to install the air fuel ratio sensor 1. CAUTION:
• Handle it carefully and avoid impacts.
• Before installing a new air fu el ratio sensor 1, clean the
exhaust tube threads using suitable tool and approved
anti-seize lubricant.
• Do not over-tighten the air fu el ratio sensor 1. Doing so
may damage the air fuel ratio sensor 1, resulting in the
MIL coming on.

INSPECTION AFTER REMOVAL
Oil Filter
• Make sure that there is no foreign material on the oil filter (1) and check it for clogging.
• Check the oil filter (1) for damage.
• If there is some damage, replace t he oil filter (1), the plug, and the
washer as a set.
CAUTION:
Do not reuse the washer.
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour- nals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on the dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer (A).
2. If wear exceeds the limit, replace camshaft.

• If items or work required are not covered by the engine section, follow the procedures in the applica-
ble sections.
• Always use the support poin t specified for lifting.
• Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shif t of center of gravity.
• For supporting points fo r lifting and jacking point at rear axle, refer to GI-38, "
Garage Jack and
Safety Stand and 2-Pole Lift".
