INSPECTION
Valve Guides
Using a micrometer and bore gauge, take diameter readings on
valve stems and guides to check stem-to-guide clearance. Be
sure to take reading at more than one place along the length of
each stem and guide.
If clearance exceeds limit, replace valve and valve guide.
Valve stem-to-guide clearance
Valve stem diameter [A]
Valve guide bore [B] standard
In and Ex : 6.000 – 6.012 mm (0.2362 – 0.2367 in.) for 69G
type valve
In and Ex : 5.485 – 5.510 mm (0.2159 – 0.2169 in.) for 54G
type valve
If bore gauge is not available, check end deflection of valve stem
with a dial gauge instead.
Move stem end in directions (1) and (2) to measure end deflec-
tion.
If deflection exceeds its limit, replace valve stem and valve guide.

Valves
Remove all carbon from valves.
Inspect each valve for wear, burn or distortion at its face and
stem end, as necessary, replace it.
Measure thickness “a” of valve head. If measured thickness
exceeds limit, replace valve.
Valve head thickness (In and Ex)
Standard : 1.22 – 1.55 mm (0.048 – 0.061 in.)
Limit : 0.9 mm (0.035 in.)
Inspect valve stem end face for pitting and wear. If pitting or
wear is found there, valve stem end may be resurfaced, but
not too much to grind off its chamber. When it is worn out too
much that its chamber is gone, replace valve.
Check each valve for radial runout with a dial gauge and “V”
block. To check runout, rotate valve slowly. If runout exceeds
its limit, replace valve.
Limit on valve head radial runout
: 0.08 mm (0.003 in.)
Seating contact width:
Create contact pattern on each valve in the usual manner,
i.e. by giving uniform coat of marking compound to valve
seat and by rotatingly tapping seat with valve head. Valve
lapper (tool used in valve lapping) must be used.
Pattern produced on seating face of valve must be a continu-
ous ring without any break, and the width of pattern must be
within specified range.
Standard seating width “a” revealed by contact pattern on
valve face
In and Ex : 1.1 - 1.3 mm (0.0433 - 0.0512 in.)

ENGINE MECHANICAL (M13 ENGINE) 6A1-51
Check cylinder head for cracks on intake and exhaust ports,
combustion chambers, and head surface.
Using a straightedge and thickness gauge, check flatness of
gasketed surface at a total of 2 locations. If distortion limit,
given below, is exceeded, correct gasketed surface with a
surface plate and abrasive paper of about #400 (Waterproof
silicon carbide abrasive paper): place abrasive paper on and
over surface plate, and rub gasketed surface against paper
to grind off high spots. Should this fail to reduce thickness
gauge readings to within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint is
often due to warped gasketed surface: such leakage results
in reduced power output.
Limit of distortion for cylinder head surface on piston side
: 0.03 mm (0.001 in.)
Distortion of manifold seating faces:
Check seating faces of cylinder head for manifolds, using a
straightedge and thickness gauge, in order to determine
whether these faces should be corrected or cylinder head
replaced.
Limit of distortion for cylinder head surface on intake and
exhaust manifold
: 0.05 mm (0.002 in.)
