I. Lightly tap the end of the valve stem once or
twice with a soft mallet to ensure that valve spring
retainer is tightly seated in the valve stem groove.
J. Install valve cap (
E
) on end of valve stem.
2. See Figure 59. Install intake valve (
F
) assembly as
follows:
A. Lightly lubricate inside diameter of valve stem
seal (
G
) with clean engine oil.
NOTE:
Inadequate precautions may cause the
valve stem seal to catch the edge of the valve
stem retainer groove. The resulting damage may
lead to leakage around the valve stem causing
increased oil consumption and possible valve
sticking.
NOTE:
Valve stem seal is not replaceable.
Damage to the valve stem seal requires cylinder
head replacement.
B. Apply a suitable engine assembly lube to the
valve stem.
C. From the bottom of the cylinder head, insert the
valve stem into the valve guide.
D. To distribute the assembly lube evenly around
the valve stem and guide, hand spin the valve
as it is installed. Work the valve back and forth in
the bore to verify that it slides smoothly and seats
properly.
E. Using a suitable degreaser, thoroughly clean
valve face, valve guide, and end of valve stem of
any excess assembly lube.
F. Install valve spring (
H
) over the valve stem and
valve guide.
G. Set the valve spring retainer (
I
) on top of the
valve spring. Using thumbs to compress valve
spring, guide the end of the valve stem through
the larger offset hole in the valve spring retainer.
Continue pressing down until the smaller center
hole engages the valve stem groove.
H. Verify that the axis of the valve spring is parallel
to the valve stem. A slanting or leaning valve
spring will result in premature valve guide wear.
I. Lightly tap the end of the valve stem once or
twice with a soft mallet to ensure that valve spring
retainer is tightly seated in the valve stem groove.
J. Install valve cap (
J
) on end of valve stem.
3. Cover the cylinder head to protect it from dust and dirt
until time of installation.
