INSPECTION
1. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY LH
(a) Using a precision straightedge and feeler gauge, measure the warpage of the contact surface of the cylinder head.
Maximum warpage: 0.50 mm (0.0197 in.)
If the warpage is greater than the maximum, replace the exhaust manifold.
2. INSPECT EXHAUST MANIFOLD SUB-ASSEMBLY RH
(a) Using a precision straightedge and feeler gauge, measure the warpage of the contact surface of the cylinder head.
Maximum warpage: 0.50 mm (0.0197 in.)
If the warpage is greater than the maximum, replace the exhaust manifold.
3. INSPECT CYLINDER HEAD SET BOLT
(a) Using a vernier caliper, measure the thread outside diameter of the bolt.
Measuring point:
Standard outside diameter: 9.810 to 9.960 mm (0.386 to 0.392 in.)
Minimum outside diameter: 9.700 mm (0.382 in.)
If the outside diameter is less than the minimum, replace the set bolt.
HINT: If a visual check reveals no excessively thin areas, check the center of the bolt (see illustration) and find the area that has the lowest diameter.
4. INSPECT CAMSHAFT SUB-ASSEMBLY
(a) Inspect the circle runout.
(1) Place the camshaft on V-blocks.
(2) Using a dial indicator, measure the circle runout at the center journal.
Maximum circle runout: 0.03 mm (0.00118 in.)
If the circle runout is greater than the maximum, replace the camshaft.
(b) Inspect the cam lobes.
(1) Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
Minimum cam lobe height:
If the cam lobe height is less than the minimum, replace the camshaft.
(c) Inspect the camshaft journals.
(1) Using a micrometer, measure the journal diameter.
Standard journal diameter: 26.954 to 26.970 mm (1.061 to 1.062 in.)
(2) Using a micrometer, measure the journal diameter of the camshaft timing tube.
Standard journal diameter: 30.984 to 31.000 mm (1.2198 to 1.2204 in.)
