CAUTION
Be sure to use the correct tool to avoid damage to the valve guide and to locate
the valve guide to the proper dimension.
3. Position the valve guide squarely in the bore in the cylinder head and press the installing tool gently to
start the guide in place (Fig. 8). Then press the guide in until the tool contacts the cylinder head (the bottom of
the counterbore in the four-valve cylinder head).
CAUTION
Do not use the valve guides as a means of turning the cylinder head over or in handling the cylinder head.
Inspect the exhaust valve seat inserts for excessive wear, pitting, or cracking.

The valve seat inserts are pressed into the cylinder head and must be removed as outlined in the following
procedure to avoid damage to the cylinder head:
1. Place the cylinder head on its side on a bench as shown in Fig. 9.
2. Place the collet of tool J 7774 inside-the valve insert so that the bottom of the collet is flush with the
bottom of the insert.
