G. Inspect camshaft thrust clearance
(a) Install the camshaft.
(See step 4 on pages EG1±69 to 71)
(b) Using a dial indicator, measure the thrust clearance
while moving the camshaft back and forth.
Standard thrust clearance:
Intake
0.045 ± 0.100 mm (0.0018 ± 0.0039 in.)
Exhaust
0.030 ± 0.085 mm (0.0012 ± 0.0033 in.)
Maximum thrust clearance:
Intake
0.12 mm (0.0047 in.)
Exhaust
0.10 mm (0.0039 in.)
If the thrust clearance is greater than maximum, re±
place the camshaft. If necessary, replace the bearing
caps and cylinder head as a set.
H. Inspect camshaft gear backlash
(a) Install the camshafts without installing the exhaust
cam sub gear.
(See step 4 on pages EG1±69 to 71)
(b) Using a dial indicator, measure the backlash.
Standard backlash:
0.020 ± 0.200 mm (0.0008 ± 0.0079 in.)
Maximum backlash:
6.30 mm (0.0188 in.)
If the backlash is greater then maximum, replace the
camshafts. (f) Measure the Plastigage at its widest point.
Standard oil clearance:
0.025 ± 0.062 mm (0.0010 ± 0.0024 In.)
Maximum oil clearance:
0.10 mm (0.0039 in.)
If the oil clearance is greater than maximum, replace
the camshaft. If necessary, replace the bearing caps
and cylinder head as a set.
(g) Completely remove the Plastigage.

0.07 mm (0.0028 In.)
If the oil clearance is greater than maximum, replace
the lifter. If necessary, replace the cylinder head.
12. INSPECT MANIFOLDS
Using a precision straight edge and feeler gauge, mea±

Exhaust
0.28 ± 0.38 mm (0.011 ± 0.015 In.)(e) Turn the intake camshaft clockwise or counterclockwise little
by little until the exhaust camshaft sits in
the bearing journals evenly without rocking the cam±
shaft on the bearing journals.

the bearing journals evenly while tightening bearing caps
in the subsequent steps.
