7.Install the camshaft cap. (See CYLINDER HEAD ASSEMBLY (II).)

8.Remove the camshaft cap. (See CYLINDER HEAD DISASSEMBLY (I).)

9.Measure the oil clearance.

• If it exceeds the specification, replace the cylinder head.

Standard clearance

0.04—0.08 mm {0.002—0.003 in}

Maximum clearance

0.09 mm {0.0035 in}

10.Install the camshaft cap. (See CYLINDER HEAD ASSEMBLY (II).)

11.Measure the camshaft end play.

• If it exceeds the specification, replace the cylinder head or camshaft.
