2. Immediately after removing the valve guides
from the freezer, insert the valve guides
(Figure 6-28, (1)) in their proper positions.
Figure 6-28
3. Finish installing the valve guides
(Figure 6-29, (1)) into the cylinder head to the
proper height (Figure 6-29, (3)) using the valve
guide installation tool (Figure 6-29, (2)). See
Valve Guide Projection specification starting on

Reassembly of Intake and Exhaust Valves
IMPORTANT
Always install new valve stem seals.
The exhaust valve stem seals are different
than the intake valve stem seals and can be
identified by either the paint marks on the
outside of the seals or by the color of the
seal spring (Figure 6-30, (4)). Ensure they
are installed in the correct locations.
1. Oil the lip of the valve stem seal
(Figure 6-30, (2)). Using the valve stem seal
installation tool (Figure 6-30, (1)), install a new
valve stem seal on each of the valve guides
(Figure 6-30, (3)).
Figure 6-30
2. Measure the distance (Figure 6-31, (1)) from
the cylinder head to valve stem seal to ensure
proper clearance (Figure 6-31, (2)) between
the guide and the seal. See Valve Stem Seal
Projection specification on page 6-9.
