STANDARD PROCEDURE - VALVE LASH ADJUSTMENT AND VERIFICATION
NOTE: To obtain accurate readings, valve lash
measurements AND adjustments should only be
performed when the engine coolant temperature is
less than 60° C (140° F).
The 24–valve overhead system is a “low-maintenance”
design. Routine adjustments are no longer necessary,
however, measurement should still take place when
troubleshooting performance problems, or upon com-
pletion of a repair that includes removal and installa-
tion of the valve train components or injectors.
1. Disconnect battery negative cables.
2. Remove cylinder head cover (Refer to 9 - ENGINE/
CYLINDER HEAD/CYLINDER HEAD COVER(S) -
REMOVAL).
3. Using the crankshaft barring tool #7471–B, rotate crankshaft to align damper TDC mark to 12:00 o’clock position.
a. If both number one cylinder rocker levers are loose, continue to next step.
b. If both number one cylinder rocker levers are not loose, rotate crankshaft 360 degrees.

4. With the engine in this position, valve lash can be measured at the following rocker arms:INTAKE 1–2–4 /
EXHAUST 1–3–5. Measure the valve lash by inserting a feeler gauge between the rocker arm socket and cross-
head. Refer to VALVE LASH LIMIT CHART for the correct specifications. If the measurement fallswithinthe
limits, adjustment/resettingis notnecessary. If measurement finds the lashoutsideof the limits, adjustment/
resettingisrequired.
VALVE LASH LIMIT CHART
INTAKE EXHAUST
0.152 mm ( 0.006 in.) MIN. 0.533 mm (0.021 in.) MIN.
0.381 mm (0.015 in.) MAX. 0.863 mm (0.034 in.) MAX.
NOTE:
If measured valve lash falls within these specifications, no adjustment/reset is necessary. Engine operation within
these ranges has no adverse affect on performance, emissions, fuel economy or level of engine noise.
5. If adjustment/resetting is required, loosen the lock
nut on rocker arms and turn the adjusting screw
until the desired lash is obtained:
INTAKE0.254 mm (0.010 in.)
EXHAUST0.660 mm (0.026 in.) Tighten the lock
nut to 24 Nꞏm (18 ft. lbs.) and recheck the valve
lash.
6. Using the crankshaft barring tool, rotate thecrank-
shaftone revolution (360°) to align the damper
TDC mark to the 12 o’clock position.
7. With the engine in this position, valve lash can be
measured at the remaining rocker arms:INTAKE
3–5–6 / EXHAUST 2–4–6. Use the same method
as above for determining whether adjustment is
necessary, and adjust those that are found to be
outside of the limits.
8. Install the cylinder head cover (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTAL-
LATION).
9. Connect the battery negative cables.

9. With the damper TDC mark in the 12 o’clock position, add a paint mark anywhere on the gear housing cover
next to the crankshaft damper. Place another mark on the vibration damper in alignment with the mark you just
made on the cover.
10. Divide the crankshaft damper into three equally sized segments as follows:
a. Using a tape measure, measure the circumference of the crankshaft damper and divide the measurement by
three (3).
b. Measure that distance in a counterclockwise direction from the first balancer mark and place another mark
on the balancer.
c. From the second damper mark, again measure in a counterclockwise direction and place a mark on the
damper at the same distance you measured when placing the second damper mark. The damper should
now be marked in three equally spaced locations and the damper TDC mark should be in the 12 o’clock
position.
