1.4 Removing the cylinder head assembly
Remove the cylinder head assembly by lifting it
straight up.
Note: If the bonding of the cylinder head gasket
prevents the head assembly from being
separated from the cylinder block, tap the
cylinder head side face on a relatively thick
portion with a plastic hammer.
1.5 Removing the valves and valve springs
(1) Remove the valve caps and locks by
compressing the springs using a valve lifter.
(2) Remove the retainers, valve springs and valves.
Note: If the valves are reusable, mark them so that
they can be reassembled back onto their original
locations. This will ensure that the mated pairs
of valves and their seats are maintained.
1.6 Removing the valve stem seals
Remove the valve stem seals by holding each of
them with a pair of pliers.
Note: Replace the old valve stem seals with new parts
upon reassembly.
