NOTE: Be sure that all traces of lapping compound have been
cleaned off before the valves are installed.
- Lubricate all of the valve stems with a light coating of engine oil, then
install the valves into the proper ports/ guides.
- If umbrella-type valve seals are used, install them at this time. Be sure
to use a seal protector to prevent damage to the seals as they are pushed
over the valve keeper grooves. If O-ring seals are used, don't install them
yet.
- Install the valve springs and the spring retainers, and using the valve
compressing tool, compress the springs.
- If umbrella-type seals are used, just install the valve keepers (white grease
may be used to hold them in place) and release the pressure on the compressing
tool. If O-ring type seals are used, carefully work the seals into the second
groove of the valve (closest to the head), install the valve keepers and release
the pressure on the tool.
NOTE: If the O-ring seals are installed BEFORE the springs
and retainers are compressed, the seal will be destroyed.
- After all of the valves are installed and retained, tap each valve spring
retainer with a rubber mallet to seat the keepers in the retainer.
