Valve Inspection

ValveStemSeal

Inspection of valve stem seals is not needed

because NEW seals should always be installed

whenever cylinder head is removed.

Valve

Inspect valve surface, check for abnormal stem

wear and bending. If so, replace by a new one.

Valve Stem and Valve Guide Clearance

Measure valve stem and valve guide in three

places, using a micrometer and a small bore

gauge.

NOTE: Clean valve guide to remove carbon de-

posits before measuring.

Change valve if valve stem is out of specification

or has other damages such as wear or friction sur-

face.
