Valve Seals: Removal

WARNING: This page is about a different car, the 2013 Ford F-350 Super Duty and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the rocker arm shaft assembly from the cylinder head being serviced. For additional information, refer to ROCKER ARM .
  2. Remove the lower spark plug for the cylinder being serviced. For additional information, refer to ENGINE IGNITION - 6.2L (2V) .
  3. Rotate the crankshaft until the piston for the valve being serviced is at the top of its stroke.
  4. Use compressed air in the cylinder being serviced to hold both valves in position.
    • Apply a minimum of 965 kPa (140 psi) of compressed air into the cylinder.
  5. NOTE: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations. Failure to follow these instructions may result in engine damage.
    NOTE: If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve to fall into the cylinder. If air pressure must be removed, support the valve prior to removal. If a valve drops into the cylinder, remove the cylinder head. For additional information, refer to CYLINDER HEAD .

    Using a valve spring compressor, compress the valve spring and remove the valve spring retainer keys.

  6. Remove the valve spring retainer, the valve spring and the valve seal.
    • Discard the valve seal.
  7. Inspect the components. For additional information, refer to ENGINE SYSTEM - GENERAL INFORMATION .
