Measure the cylinder block bore in the engine block [Figure 70-100-15].
Measure the camshaft journal [Figure 70-100-16].
Calculate the oil clearance. If the clearance exceeds the allowable limit, replace the camshaft.
Measure the cam lobes at their highest point [Figure 70-100-17].
If the measurement is less than the allowable limit, replace the camshaft.1
Put the camshaft in V-blocks. Install a dial indicator [Figure 70-100-18].
Turn the camshaft at a slow rate. If the misalignment exceeds the allowable limit, replace the camshaft.
