Valve Guides
Replacement
1. As illustrated below, use a commerciallv available
air-impact valve guide driver attachment modified
to fit the diameter of the valve guides. ln most
cases, the same procedure can be done using the
sDecial tool and a conventional hammer.

Select the proper replacement guides and chill
them in the freezer section of a refrigerator for
about an hour.
Use a hot plate or oven to evenly heat the cylinder
head to 300"F (150"C). Monitor the temperature with
a cooking thermometer.
CAUTION:
. Do not use a torch; it may warp tho head.. Do not get tho head hotter than 300"F {150"C};excesgive heat may loosen thg valve seats.. To avoid burns. use haaw gloves whon handling
the heatod cylinder head.

Working from the camshaft side, use the driver and
an air hammer to drive the guide about 2 mm (0.1 in)
towards the combustion chamber. This will knock off
some ofthe carbon and make removaleasier.
CAUTION:
. Always wsar safety goggles or a face shield whsn
driving valve guides.
. Hold the air hammer dir€ctly in line with the
valve guide to prevont damaging thg dtiver.
Turn the head over and drive the guide out toward
the camshaft side of the head.

lf a valve guide still won't move. drill it out with a8.0 mm (5/16 in) bit, then try again.
CAUTION: Drill guides only in extreme cases; you
could damago the cylinder head if ths guide br6aks.
Remove the new guide(s) from the freezer, one at a
time, as vou need them.
