Camshaft Journal/Camshaft Cap Clearance Standard: 0.038 ∼ 0.081 mm (0.0015 ∼ 0.0032 in.) Service Limit: 0.17 mm (0.0067 in.)

If any clearance exceeds the service limit, measure the diameter of each camshaft journal with a micrometer.

Camshaft Journal Diameter Standard: 23.940 ∼ 23.962 mm (0.9425 ∼ 0.9434 in.) Service Limit: 23.91 mm (0.9413 in.)

If the clearance still remains out of the service limit, replace the cylinder head unit.
