Do you
recommend retrospectively installing valve seals on XK engines where seals
were not part of the original specification?
A
Absolutely,
yes. We install seals on the intake valves of all engines that we build
at Classic Jaguar.
Q
Is it
a straight forward installation?
A
Yes. Installing
valve seals will not necessitate any additional machine work or the use
of any special tools.
Q
I have
heard that some other parts must be swapped out during the installation
process - is this correct?
A
Yes. It
is essential that the spring seats, spring retainers and spilt collets
are substituted for the later versions that are found in later XK engines
where valve seals were installed at the factory. Use of the earlier style
components in conjunction with valve seals may result in the seals being
destroyed. The subsequent fragments of valve seal could find their way
behind the spilt collet valve retainers - with disastrous results.
Q
How can
I identify which parts I need to use in conjunction with the valve seals?
A

and late components referred to above.
