If journals are binding, also check the cylinder head bear-
ing surface for damage, and check the camshaft bearing
oil feed holes in the cylinder head for clogging.
(2) Check the cam surface for abnormal wear and damage.
Replace if defective. Also measure the cam height and
replace if out of limit.
