For 1990-2009 cars

1. Measure the straightness of the camshaft using a dial gage.
2. Replace the camshaft if the measured value is over the specified limit.

Specification
The specification limit is 0.03 mm (0.0012 in).

3. Measure the outer diameter of each journal at the 5 different places to check the abrasion of the camshaft journal.
4. Using a bore gage (1), measure the inner diameter of the cylinder head journal at the 5 places. The clearance of the journal is measured by the difference between the outer diameter of the camshaft the inner diameter of the cylinder head journal part.
