Compress the valve springs using the valve lifter.
Remove the valve collets, valve spring retainers and valve
springs.

NOTE:
Before removing the valves and the valve stem seals, it is
vital to measure position “H” of one of the old seals in rela-
tion to the cylinder head using valve seal drift [KV113B0180
(Mot. 1511-01) (commercial service tool) or equivalent tool].
