VALVES AND VALVE SPRINGS
NOTE:
Intake and exhaust valves operate in guides
that are integral with the heads.
Removal

Valve Inspection
(1) Clean the valves thoroughly, and discard
burned, warped and cracked valves.
(2) Measure the valve stems for wear. The new
in-
take valve stem diameter should measure .372 to .373
inch and exhaust valve stem diameter should measure
.371 to .372 inch. If the wear exceeds .002 inch, re-
place the valve.
(3) Remove the carbon and varnish deposits from
the inside of the valve guides with cleaner, Tool C-756.
(4) Measure the valve stem guide clearance as fol-
lows: Install sleeve, Tool C-3973 over valve stem to
hold valve at working height in head, as shown in
Fig. 73.
(5) The special sleeve places the valve at the cor-
rect height for measuring with a dial indicator. Attach
the dial indicator Tool C-3339 to cylinder head and
set it at a right angle to the valve stem being meas-
ured (Fig. 74). Move valve to and from the indicator.
Total movement should not exceed .016 inch on in-
