      Note


      • Be careful not to drop plate washers into the cylinder head sub-assembly.

      • Head warpage or cracking could result from removing bolts in incorrect order.

    2. Remove the cylinder head sub-assembly.

  18. REMOVE CYLINDER HEAD GASKET

  19. INSPECT CYLINDER HEAD SET BOLT


    1. A01BACIE03
      Text in Illustration
      *a Measuring area
      *b Distance

      Using a vernier caliper, measure the diameter of the most elongated threads in the measuring area.

      Standard outside diameter
      10.76 to 10.97 mm (0.424 to 0.432 in.)
      Minimum outside diameter
      10.40 mm (0.409 in.)
      Distance
      30 mm (1.18 in.)

      If a visual check reveals no excessively thin areas, check the center of the measuring area (see illustration) and find the area that has the smallest diameter.

      If the diameter is less than the minimum, replace the cylinder head set bolt.

  20. INSPECT CYLINDER HEAD SUB-ASSEMBLY


    1. A01BE10E02
      Text in Illustration
      *a Cylinder Head Lower Side
      *b Intake Manifold Side
      *c Exhaust Manifold Side

      Using a precision straightedge and feeler gauge, measure the warpage of the contact surface of the cylinder block and manifolds.

      Maximum warpage
      0.05 mm (0.00197 in.)

      If the warpage is more than the maximum, replace the cylinder head sub-assembly.

    2. Using a dye penetrant, check the intake ports, exhaust ports and cylinder surface for cracks.

      If cracked, replace the cylinder head sub-assembly.
