(7) Ream the inside of valve guide with ST.
Gently rotate the reamer clockwise while press-
ing it lightly into valve guide, and return it also ro-
tating clockwise. After reaming, clean the valve
guide to remove chips.
CAUTION:
Apply engine oil to the reamer when reaming.
If the inner surface of the valve guide is torn,
the edge of the reamer should be slightly
ground with an oil stone.
If the inner surface of the valve guide be-
comes lustrous and the reamer does not chips,
use a new reamer or remedy the reamer.
