    CAUTION: In order to prevent damage to the valves and injectors during cylinder head removal, set the cylinder head on blocks.
  13. Remove the cylinder head gasket (3).

  15. Use the following procedures when cleaning the cylinder head and cylinder block surfaces:

There will be indentations from the gasket left in the cylinder head after all of the gasket material is removed. These small indentations will be filled in by the new gasket.

    • Do not use any other method or technique to clean these gasket surfaces.
  16. Clean the old sealer/lube and dirt from the bolt holes.
    NOTE: Do not use a tap to clean the cylinder head bolt holes.
  17. Clean the bolt holes with a nylon bristle brush.
  18. When cleaning the cylinder head bolt holes use a suitable commercial spray liquid solvent and compressed air from an extended-tip blow gun to reach the bottom of the holes.
    WARNING: Wear safety glasses to avoid injury when using compressed air or any cleaning solvent. Bodily injury may occur if fumes are inhaled or if skin is exposed to chemicals.
  19. Remove any broken long cylinder head bolts using the EN 38188  kit.
