Inspection and AdjustmentINFOID:0000000005398043
INSPECTION
Perform inspection as follows after removal, installation or
replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-46, "
Exploded View".
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke. • Rotate crankshaft pulley (2) clockwise and align TDC mark(without paint mark) (A) to timing indicator (1) on front cover.
• At the same time, make sure that both intake and exhaust cam noses of No. 1 cylinder face inside as shown.
• If they do not face inside, rotate crankshaft pulley once more (360 degrees) and align as shown.
b. Use a feeler gauge, measure the clearance between valve lifter and camshaft.
• Measure the valve clearances at locations marked “ ×” as
shown in the table below [locations indicated with black arrow
( ) as shown] with a feeler gauge.

c. Rotate crankshaft pulley (2) one revolution (360 degrees) and
align TDC mark (without paint mark) (A) to timing indicator (1) on
front cover.
• Measure the valve clearance at locations marked “ ×” as shown
in the table below [locations indicated with black arrow ( ) as
shown] with a feeler gauge.
3. If out of standard, perform adjustment procedure.
ADJUSTMENT
• Perform adjustment depending on selected head thickness of valve lifter.
1. Remove camshaft. Refer to EM-59, "
Exploded View".
2. Remove valve lifters at the loca tions that are out of the standard.
3. Measure the center thickness of the removed valve lifters with a micrometer (A).
4. Use the equation below to calculate valve lifter thickness for replacement.

10. Remove intake manifold support (center) from cylinder head, if necessary. NOTE:
The intake manifold support (center) functions as the guide when the intake manifold is installed.
INSTALLATION
Installation is in the reverse order of removal.
Intake Manifold
1. Install the gasket to the intake manifold.• Align the protrusion (A) of gasket to the groove of intake mani-fold.
2. Place the intake manifold into the installation position. CAUTION:
Make sure that the oil level gauge guide is not disconnected from the fixing clip of water inlet due
to interference with intake manifold.
