6. Remove valve guide seals. IMPORTANT: It is
recommended to replace seals whenever the
cylinder head is disassembled. Hardened,
cracked or worn valve seals will cause excessive
oil consumption and carbon buildup.
7. Mark the valves with a white pen. Remove the
valves from the cylinder head. This will ensure
that the valves are properly placed during engine
reassembly.
