CYLINDER HEAD
1.
Inspect for flatness.
Using a precision straight edge and feeler gauge,
measure the surface the contacting the cylinder block
and the manifolds for warpage.
Flatness of cylinder head gasket surface
Standard : Less than 0.05mm(0.002in.)[Less
than 0.02mm(0.0008in.)/150x150]
Flatness of manifold gasket surface
Standard : Less than 0.03mm(0.001in)/110x110

2.
Inspect for cracks.
Check the combustion chamber, intake ports, exhaust
ports and cylinder block surface for cracks. If cracked,
replace the cylinder head.
VALVE AND VALVE SPRING
1.
Inspect valve stems and valve guides.
1)
Using a caliper gauge, measure the inside diam-
eter of the valve guide.
Valve guide I.D.
Intake / Exhaust : 5.500 ~ 5.512mm (0.216 ~ 0.217in.)
ECBF034A
2)
Using a micrometer, measure the diameter of the
valve stem.
Valve stem O.D.
Intake : 5.465 ~ 5.480mm (0.2151 ~ 0.2157in.)
Exhaust : 5.458 ~ 5.470mm (0.2149 ~ 0.2153in.)
