INSPECTION AND REPAIR
1. Clean all parts, taking care to remove any gasket fragments, dirt, oil or grease, carbon, moisture
residue, or other foreign materials.
2. Inspect and repair must be performed in the order specified.
Caution
Be careful not to damage the joints or friction surfaces of aluminum alloy components (such
as the cylinder head or pistons).
86U01X-077
Cylinder Head
1. Inspect the cylinder head for damage, cracks, and
leakage of water or oil. Replace if necessary.
2. Measure the cylinder head distortion in the six
directions shown in the figure.
Distortion: 0.15 mm (0.006 in) max.
79G01C-106
If the cylinder head distortion exceeds specifica-
tion, grind the cylinder head surface.
If the cylinder head height is not within specifica-
tion, replace it.
Height:
91.95—92.05 mm (3.620—3.624 in)
Grinding limit: 0.20 mm (0.008 in) max.
Note
Before grinding the cylinder head, first check
the following. Replace if necessary.
• Sinking of valve seat
• Damage of manifold contact surface
• Camshaft oil clearance and end play
Measure the manifold contact surface distortion in
the six directions shown in the figure.
Distortion: 0.15 mm (0.006 in) max.
If distortion exceeds specification grind the surface
or replace the cylinder head.

(2) Method No. 2
Measure the valve stem play at a point close
to the valve guide with the valve lifted slightly
off the valve seat.
Clearance
IN : 0.025—0.060 mm (0.0010—0.0024 in)
EX: 0.030—0.065 mm (0.0012—0.0026 in)
Maximum: 0.20 mm (0.0079 in)
7. If the clearance exceeds the maximum, replace the
valve and/or valve guide.
8. Check that the valve guide projection height
(dimension A in the figure). Replace if necessary.
Height:
19.8—20.3 mm (0.780—0.799 in)... 12-valve
19.1—19.6 mm (0.752—0.772 in)...8-valve
Replacement of valve guide
Note
Although the shapes of the intake and exhaust
valve guides are different, use the exhaust
valve guide on both sides as a replacement.
86U01X-214
Removal
1. Gradually heat the cylinder head in water to ap-
prox. 90°C (194°F).

2. Remove the valve guide from the side opposite the
combustion chamber with the SST.
3. Remove the valve guide clip (8-valve).
Installation
1. Fit the clip onto the valve guide (8 valve).
2. Gradually heat the cylinder head in water to ap-
prox. 90°C (194°F).
3. Tap the valve guide in from the side opposite the
combustion chamber with the SST until the projec-
tion height is as specified.
Valve Seat
1. Inspect the contact surface of the valve seat and
valve face for the following.
(1) Roughness
(2) Damage
2. If necessary, resurface the valve seat with a 45°
valve seat cutter and/or resurface the valve face.
3. Apply a thin coat of prussian blue to the valve face.
4. Check the valve seating by rotating the valve
against the seat.
(1) If blue does not appear 360° around the valve
face, replace the valve.
(2) If blue does not appear 360° around the valve
seat, resurface the seat.
