Valves and Valve Guides Inspection
Valve Guide
Valve stem-to-guide clearance
Using a micrometer and bore gauge, take diameter
readings on valve stems and guides to check stem-to-
guide clearance.
Be sure to take reading at more than one place along the
length of each stem and guide.
If clearance exceeds limit, replace valve and valve
guide.

Valve stem end deflection
If bore gauge is not available, check end deflection of
S6JB0A1416025
valve stem with a dial gauge instead.
Move stem end in directions (1) and (2) to measure end
deflection.
If deflection exceeds its limit, replace valve stem and
valve guide.
