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.
INSTALLATION

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 fuel ratio sensor 1, clean theexhaust 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 rati o 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.

ENGINE ASSEMBLY
1. Remove front wheel sensor (LH and RH) for ABS from steering knuckle (if equipped). Refer to BRC-34,
"Removal and Installation" (ABS).
2. Remove brake caliper assembly with piping connected fr om steering knuckle. Temporarily secure it on the
vehicle side with a rope to avoid load on it. Refer to BR-25, "
Component".
3. Remove drive shafts (LH and RH) from steering knuckle. Refer to FA X - 9 , "
Removal and Installation (Left
Side)" and FAX-10, "Removal and Installation (Right Side)".
4. Remove exhaust front tube. Refer to EX-6, "
Component".
5. Remove rear torque rod. NOTE:
A/T models shown.
6. Remove A/T cooler hoses from transmission (if equipped).
7. Preparation for the separation work of transaxle is as follows: • Remove transaxle joint bolts which pierce at oil pan (upper) lower rear side. Refer to EM-42, "
Compo-
nent".
Removal
1. Install engine slinger to cylinder head front left side (A) and rear
right side (B) and support the engine with a hoist.
2. Lift with a hoist and secure the engine in appropriate position.
3. Use a suitable tool (A) to securely support bottom of the engine and the transaxle assembly and simultaneously adjust hoist ten-
sion.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.

• Avoid impacts such as a dropping.
• Never disassemble.
• Keep it away from metal particles.
• Never place the sensor where it is exposed to magnetism.
4. Remove piston and connecting rod assembly with the following procedure: • Before removing piston and connecting rod assembly, check the connecting rod side clearance. Refer toEM-97, "
Inspection".
a. Position crankshaft pin corresponding to connecting rod to be removed onto the bottom dead center.
b. Remove connecting rod cap.
c. Using a hammer handle or similar tool, push piston and connect- ing rod assembly out to the cylinder head side.
CAUTION:
• Be careful not to damage matching surface with connect-ing rod cap.
• Be careful not to damage the cylinder wall and crankshaft pin, resulting from an inte rference of the connecting rod
big end.
5. Remove connecting rod bearings. CAUTION:
Identify installation positions, and store them without mixing up.
6. Remove piston rings from piston. • Before removing piston rings, check the piston ring side clearance. Refer to EM-97, "
Inspection".
• Use suitable tool (A).
CAUTION:
• When removing piston rings, be careful not to damagethe piston.
• Be careful not to damage piston rings by expanding
them excessively.

CRANKSHAFT END PLAY
• Measure the clearance between thrust bearings and crankshaft arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
• If the measured value exceeds the limit, replace thrust bearings, and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE
• Measure the side clearance between connecting rod and crank-shaft arm with a feeler gauge (A).
• If the measured value exceeds the limit, replace connecting rod, and measure again. If it still exceeds the standard, replace crank-
shaft also.
