(2)Remove the spring retainer.
(3) Remove the valve spring.
(4) Remove the valve.

INSPECTION
CYLINDER HEAD
1. Inspect for flatness.
Using a precision straight edge and feeler gauge, measure the surface contacting cylinder block and the manifolds
for warpage.
Flatness of cylinder head gasket surface
Standard : 0.03mm(0.0012in.) or less
Flatness of manifold gasket surface
Standard : 0.15mm(0.0059in.) or less
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 diameter of the valve guide.
Valve guide inside diameter
Intake / Exhaust : 6.000 ~ 6.015mm (2.2362 ~ 2.2368in.)
(2)Using a micrometer, measure the outer diameter of the valve stem.
Valve stem outer diameter
Intake : 5.585 ~ 5.980mm (0.2348 ~ 0.2354in.)
Exhaust : 5.950 ~ 5.595mm (0.2343 ~ 0.2348in.)
(3)Calculate the clearance between the valve guides and the stems by difference between the valve stem
measured diameter and the valve guide measured inside diameter.
Valve stem - to- guide clearance
[Standard]
Intake : 0.020 ~ 0.050mm (0.0008 ~ 0.0020in.)
Exhaust : 0.035 ~ 0.065mm (0.0014 ~ 0.0026in.)
[Limit]
Intake : 0.10mm (0.0039in.) or less
Exhaust : 0.13mm (0.0051in.) or less
2. Inspect valves.
(1) Check the valve face angle.
(2) Check that the surface of the valve for wear.
If the valve face is worn, replace the valve.
(3) Check the valve head margin thickness.

If the margin thickness is less than the specification, replace the valve.
Specification
Intake : 1.0mm(0.0394in.)
Exhaust : 1.3mm(0.0512.)
(4)Check the valve length.
Length
Intake : 110.1mm(4.3346in)
Exhaust : 111.1mm(4.3740in)
(5) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, replace the valve.
3. Inspect valve seats
(1) Check the valve seat for evidence of overheating or improper contact with the valve face.
If the valve seat is worn, replace cylinder head.
(2) Before reconditioning the seat, check the valve guide for wear. If the valve guide is worn, replace the valve
guide first.
(3) Recondition the valve seat with a valve seat grinder or cutter. The valve seat contact width should be within
specifications and centered on the valve face.
4. Inspect valve springs.
(1) Using a steel square, measure the out - of- square of the valve spring.
(2) Using vernier calipers, measure the free length of the valve spring.
Valve spring
[Standard]
Free height : 46.8mm (1.8425in.)
Out- of- square : 1.5° or less

MLA(Mechanical Lash Adjuster)
1.Inspect MLA.
Using a micrometer, measure the MLA outside diameter.
MLA O.D.
Intake/Exhaust : 29.964 ~ 29.980mm(1.1797 ~ 1.1803in.)
2. Using a caliper gauge, measure MLA tappet bore inner diameter of cylinder head.
Tappet bore I.D.
Intake/Exhaust : 30.000 ~ 30.025mm(1.1811 ~ 1.1821in.)
3. Calculate the clearance by subtracting MLA outside diameter measurement from tappet bore inside diameter
measurement.
MLA to tappet bore clearance
[Standard]
Intake/Exhaust : 0.020 ~ 0.061mm(0.0008 ~ 0.0024in.)
[Limit]
Intake/Exhaust : 0.07mm(0.0027in.) or less
CAMSHAFT
1.Inspect cam lobes.
Using a micrometer, measure the cam lobe height.
Cam height
[Standard value]
Intake : 44.5mm (1.7520in.)
Exhaust : 44.5mm (1.7520in.)
If the cam lobe height is less than standard, replace the camshaft.
2. Check the cam lobe surface for wear or damage. If necessary, replace it.
3. Inspect camshaft journal clearance.
(1) Clean the bearing caps and camshaft journals.
(2) Place the camshafts on the cylinder head.
(3) Lay a strip of plastigage across each of the camshaft journals.
