CYLINDER HEAD
STANDARD PROCEDURE - VALVE SERVICE
This procedure is done with the engine cylinder
head removed from the block.
DISASSEMBLY
(1) Remove the engine cylinder head from the cyl-
inder block. Refer to cylinder head removal and
installation in this section.
(2) Use Valve Spring Compressor Tool and com-
press each valve spring.
(3) Remove the valve locks, retainers, and springs.
(4) Use an Arkansas smooth stone or a jewelers
file to remove any burrs on the top of the valve stem,
especially around the groove for the locks.
(5) Remove the valves, and place them in a rack in
the same order as removed.
VALVE CLEANING
(1) Clean all carbon deposits from the combustion
chambers, valve ports, valve stems, valve stem
guides and head.
(2) Clean all grime and gasket material from the
engine cylinder head machined gasket surface.
INSPECTION
(1) Inspect for cracks in the combustion chambers
and valve ports.
(2) Inspect for cracks on the exhaust seat.
(3) Inspect for cracks in the gasket surface at each
coolant passage.
(4) Inspect valves for burned, cracked or warped
heads.
(5) Inspect for scuffed or bent valve stems.
(6) Replace valves displaying any damage.
(7) Check valve spring height (Fig. 12).
VALVE REFACING
(1) Use a valve refacing machine to reface the
intake and exhaust valves to the specified angle.
(2) After refacing, a margin of at least 4.52-4.49
mm (.178-.177 inch) must remain (Fig. 13). If the
margin is less than 4.49 mm (.177 inch), the valve
must be replaced.
VALVE SEAT REFACING
(1) Install a pilot of the correct size in the valve
guide bore. Reface the valve seat to the specified
angle with a good dressing stone. Remove only
enough metal to provide a smooth finish.
(2) Use tapered stones to obtain the specified seat
width when required.
VALVE STAND DOWN
Valve stand down is to maintain the adequate com-
pression ratio.
(1) Invert cylinder head.
(2) Fit each valve to its respective valve guide.
(3) Using a straight edge and feeler gauge, check
valve head stand down: Inlet valve head stand down
1.08 to 1.34 mm (.042 to .052 ins.) and exhaust valve
stand down .99 to 1.25 mm (.035 to .049 ins.).
(4) If valve head stand down is not in accordance
with above, discard original valves, check stand down
with new valves and recut valve seat inserts to
obtain correct stand down.
VALVE GUIDES
(1) Valve Guides height requirement.
(2) Measurement A (Fig. 14): 13.50 - 14.00 mm.
VALVE STEM-TO-GUIDE CLEARANCE
MEASUREMENT
(1) Measure and record internal diameter of valve
guides. Valve guide internal diameter is 8.0 to 8.015
mm (.3149 to .3155 ins.).
(2) Measure valve stems and record diameters.
Intake valve stem diameter 7.94 to 7.96 mm (.3125 to
.3133 in). Exhaust valve stem diameter 7.92 to 7.94
mm (.3118 to .31215 in).
