1) Measure the bend, and repair or replace if nec­essary.
Limit:
0.025 mm (0.0010 in)

2. CAMSHAFT SUPPORT
Measure the thrust clearance of camshaft with dial gauge. If the clearance exceeds the limit, replace camshaft support.
Standard:
0.030 - 0.090 mm (0.0012 - 0.0035 in)
Limit:
0.10 mm (0.0039 in)
2)  Check journal for damage and wear. Replace if faulty.
3)   Measure outside diameter of camshaft journal and inside diameter of cylinder head journal, and determine the difference between the two (= oil clearance). If oil clearance exceeds specifications, replace camshaft or cylinder head as necessary.
