NOTE: Since each tire/wheel assembly weighs approximately 14 kg (30 lbs), placing the front wheels in trunk can assist
with the weight distribution.
1. Place the lift blocks as shown
2. Raise the hoist a lew inches (centimeters) and rock the car to be sure it is firmly supported.
3. Raise the hoist to full height and inspect lift points for solid support.

Camshafts
Inspection
Loosen the adjusting screws.
Remove the camshaft holders and the rocker arms
NOTE: Mark the rocker arms before removing
them.
Reinstall the camshaft and holders. Tighten the
camshaft holder bolts in a crisscross pattern, begin-
ning with the inner bolts.
9.8 N.m (1.0 kgf.m,7.2 lbf.ft)
Seat the camshafts by pushing them toward the dis-
tributor end of the head with a screwdriver.
Zero the dial indicator against the end of the
camshaft. push the camshaft back and forth and
read the end play.
Camshalt End Play:
St.ndard lNow): 0.05 - 0.15 mm
(0.002 - 0.006 inl
Seivice Limit: 0.5 mm {0,02 in)
Remove the camshaft holder bolts from the cylinder
head.
NOTE: Unscrew the camshaft holder bolts two
turns at a time, in a crisscross pattern.
Lift the camshafts out ot the cylinder head. wipe
them clean, then inspect the lift ramps. Replace the
camshaft if any lobes are pitted, scored, or exces-
srvely worm
Clean the camshaft journal surfaces in the cylinder
head, then set the camshaft back in place. Insert a
plastigage strip across each iournal.
Install the camshaft holders and torque the bolts to
the values and in the sequence shown on page 6-30.
NOTE: Do not rotate camshafts during inspection.

10.Remove the camshaft holders. Measure the widest
ponion of plastigage on each journa..

11. lf camshaft-to-holder oil clearance is out of toler
ance:
. And the camshaft has already been replaced,
vou must replace the cylinder head.
. lf the camshaft has not been replaced, first check
total runout with the camshaft supported on V-
blocks.

Servico Limit: o.Oil mm {0.002 inl
- lf the total runout of the camshafts is within tol-
erance, replace the cylinder head.
- lf the total runout is out of tolerance, replace the
camshafts and recheck. lf the oil clearance is still
out of tolerance. replace the cylinder head.

Installation
Installthe cylinder head in the reverse order of removal:
NOTE:
. Always use a new head gasket.
. Cylinder head and cylinder block surface must be
ctean.
. "UP" mark on the timing belt pulleys should be at the
top.
. Do not use the middle cover and lower cover for stor-
ing items disassembled.
. Clean the middle cover and lower cover before instal-
lation.
. Replace the washer when damaged or deteriorated.'1. Cylinder head dowel pins and the oil control orifice
must be aligned,
NOTE:
. When handling a metal gasket, care should be
taken not to told it or damage the contact surface
of the gasket.
. Clean the oil control orifice when installing.

the same sequence to 83 N.m (8.5 kgf.m, 61 lbf'ft).
NOTE:
. Apply engine oil to the cylinder head bolts and
the washers.
. Use the longer bolts at positions No. 1 and No. 2
as shown.

NOTE: lf camshaft-to-holder oil clearances (see page 6-
21) are not within specitication, the head cannot be
resurfaced.
lf camshaft'to-holder oil clearances are within specifica-
tions, check the head for warpage.
lf warpage is less than 0.05 mm (0.002 in) cylinder
head resurtacing is not required.
lf warpage is between 0.05 mm (0.002 in) and 0.2 mm
(0.008 in), resurface cylinder head.
Maximum resurface limit is 0.2 mm (0.008 in) based
on a height of 132.0 mm (5.20 in).
Measure along edges, and 3 ways across center.
