INTAKE/EXHAUST VALVES &
SEATS
DESCRIPTION
The valves are made of heat resistant steel, and
have chrome plated stems to prevent scuffing. Theintake and exhaust valves are both similar in head
diameter and overall length, but they have unique
face angles which makes them non-interchangeable.
The valves are distinguished by unique dimples on
the exhaust valve head (Fig. 35) .
The exhaust valve springs are made from high
strength, chrome silicon steel. The exhaust valve
springs are also exhaust brake compatible.

STANDARD PROCEDUREÐVALVE LASH
ADJUSTMENT AND VERIFICATION
NOTE: To obtain accurate readings, valve lash mea-
surements AND adjustments should only be per-
formed when the engine coolant temperature is less
than 60É C (140É F).
The 24±valve overhead system is a ªlow-mainte-
nanceº design. Routine adjustments are no longer
necessary, however, measurement should still take
place when trouble-shooting performance problems,or upon completion of a repair that includes removal
and installation of the valve train components.
(1) Disconnect battery negative cables.
(2) Remove cylinder head cover (Fig. 47) (Refer to
9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
(3) Remove the crankcase breather and vapor can-
ister (Fig. 48).
(4) Using the crankshaft barring tool #7471±B,
rotate the engine and align the pump gear mark with
the top dead center (TDC) mark on the gear housing
cover (Fig. 49).
(5) With the engine in this position (pump gear
mark at 12 o'clock), valve lash can be measured at
the following rocker arms:INTAKE 1±2±4 /
EXHAUST 1±3±5. Measure the valve lash by insert-
ing a feeler gauge between the rocker arm socket and
crosshead (Fig. 50). Refer to VALVE LASH LIMIT
CHART for the correct specifications. If the measure-
ment fallswithinthe limits, adjustment/resettingis
notnecessary. If measurement finds the lashout-
sideof the limits, adjustment/resettingisrequired.
