Cylinder Head Disassembly
1. Carefully remove the cylinder components.
2. Place the hydraulic lifters (C), pushrods (D), and rocker
arms (E) in a safe, clean area.
3. Measure free length of spring with a Vernier caliper.
Compare to specifications. Replace spring if measurement
is out of specification.
4. 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.
5. 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.
