. lf the measurement exceeds the service limit,
recheck using a new valve.
. lf the measurement is now within the service
limit, reassemble using a new valve.
. lf the measurement still exceeds the limit,
recheck using the alternate method below, then
replace the valve and guide, if necessary.
NOTE: An alternate method of checking guide to
stem clearance is to subtract the O.D. of the valve
stem, measured with a micrometer, from the l.D. of
the valve guide, measured with an inside
micrometer or ball gauge. Take the measurements
in three places along the valve stem and three
places inside the valve guide. The difference be-
tween the largest guide measurement and the
smallest stem measurement should not exceed the
service limit.

Rocker Arms
Removal
'1. Hold the rocker arms together with a rubber band to
prevent them from separating.
Remove the intake and exhaust rocker shaft oil con-
trol orifices, then remove the VTEC solenoid valve
and the sealing bolts.
NOTE: The shapes ofthe intake and exhaust oil con-
trol orifices are different, ldentify the parts as they
are removed to ensure reinstallation in the original
locauons.
