INSPECTION(continued)





5. INSPECT CAMSHAFT TIMING TUBE ASSEMBLY
(a) Using a micrometer, measure the journal diameter.
Standard journal diameter: 39.955 to 39.964 mm (1.5730 to 1.5734 in.)
If the journal diameter is not as specified, replace the camshaft timing tube and check the oil clearance.





(b) Install the timing tube to the intake camshaft, and check that the timing tube turns smoothly. If necessary, replace the timing tube and intake camshaft.





6. INSPECT CAMSHAFT GEAR SPRING
(a) Using a vernier caliper, measure the gap distance of the gear spring.
Gap distance: 18.2 to 18.8 mm (0.717 to 0.740 in.)
If the gap distance is not as specified, replace the gear spring.





7. INSPECT CAMSHAFT OIL CLEARANCE
(a) Clean the bearing caps and camshaft journals.
(b) Check the bearings for flaking and scoring. If the bearings are damaged, replace the cylinder head sub-assembly.
(c) Place the camshafts on the cylinder head.
(d) Lay a strip of Plastigage across each of the camshaft journals.
(e) Install the bearing caps.

HINT:
^ for Bank 1, refer to the following procedures.
^ for Bank 2, refer to the following procedures.

NOTICE: Do not turn the camshaft.

(f) Remove the bearing caps.

HINT:
^ for Bank 1, refer to the following procedures.
^ for Bank 2, refer to the following procedures.





(g) Measure the Plastigage at its widest point.

Standard oil clearance:

Maximum oil clearance:

If the oil clearance is greater than the maximum, replace the camshaft. If necessary, replace the cylinder head sub-assembly.
(h) Remove the camshafts.
(i) Completely remove the Plastigage.
8. INSPECT VALVE CLEARANCE
9. INSPECT TIMING BELT
10. INSPECT TIMING BELT TENSIONER ASSEMBLY
11. INSPECT NO. 1 TIMING BELT IDLER SUB-ASSEMBLY
12. INSPECT CYLINDER HEAD SUB-ASSEMBLY
13. INSPECT VALVE LIFTER
14. INSPECT CAMSHAFT THRUST CLEARANCE
15. INSPECT CAMSHAFT GEAR BACKLASH
16. INSPECT CYLINDER BLOCK SUB-ASSEMBLY
