11.
Install new valve guide oil seal (Figure 4, Item 1) as follows:
a.
Slide valve (Figure 4, Item 4) into position in cylinder head (Figure 4, Item 3).
NOTE
Installation caps come with the new valve guide seals and are disposed of when job is
complete.
b.
Place plastic seal installation cap (Figure 4, Item 2) on end of valve (Figure 4, Item 4).
c.
If installation cap (Figure 4, Item 2) extends more than 0.16 in. (1.59 mm) below groove on valve
(Figure 4, Item 4), remove cap (Figure 4, Item 2) and cut off excess length.
d.
Lubricate installation cap with clean engine oil and start seal (Figure 4, Item 1) carefully onto the valve
(Figure 4, Item 4).
NOTE
The oil seal installation tool will position oil seal so it does not bottom out on the valve
guide. If oil seal is installed too far and makes contact with the top of valve guide, it will
distort and will not provide effective sealing.
e.
With the spring seat washer removed, use installation cap (Figure 4, Item 2) to push the valve guide oil
seal (Figure 4, Item 1) down until the tool bottoms on valve guide (Figure 4, Item 5).
f.
Remove the installation cap (Figure 4, Item 2).
