Remove new valve guides from the refrigerator one at a
time as needed.
Drive the exhaust valve guide [1] until the valve guide
clip [2] is fully seated as shown from the valve spring
side of the cylinder head.
Drive the intake valve guide [4] to the specified height
(measured from the end of the valve guide to the
cylinder head as shown) from the valve spring side of
the cylinder head.
After installing the valve guide, check the guide for
damage.
Replace the valve guide if damaged.
Let the cylinder head cool to room temperature.
Ream the valve guide (page 12-9).
VALVE GUIDE REAMING
For best results, be sure the cylinder head is at room
temperature before reaming valve guides.
Coat the reamer and valve guide with cutting oil.
Rotate the reamer clockwise through the valve guide
the full length of the reamer.
• Turn the special tool (valve guide reamer) clockwise,
never counterclockwise.
• Continue to rotate the special tool while removing it
from the valve guide.
Thoroughly clean the cylinder head to remove any
cutting residue.
Check the valve guide bore; it should be straight, round
and centered in the valve guide. Insert the valve and
check operation. If the valve does not operate
smoothly, the guide may have been bent during
installation.
Replace the cylinder head if it is bent or damaged
(page 12-4).
Check the valve stem-to-guide clearance (page 12-7).
