- For valve cover gasket:
  - Remove any components obstructing access to the valve cover (e.g., air intake).
  - Unbolt the valve cover using a socket set.
  - Remove the old gasket and clean the mating surfaces.
  - Place the new gasket on the valve cover and reinstall it, tightening the bolts to the manufacturer’s specified torque (consult repair manual for torque specifications).
Seal Replacement:
- For crankshaft seal:
  - Remove the harmonic balancer if necessary (consult specific service manual).
  - Use a seal puller to remove the old crankshaft seal.
