Cylinder Block

  1. If maximum deck warpage exceeds specification, resurface deck. See CYLINDER BLOCK  under ENGINE SPECIFICATIONS. If resurfacing reduces deck height to less than minimum specification, replace cylinder block. Maximum resurfacing limit of cylinder head and/or cylinder block combined is .008" (.20 mm).
  2. Standard diameter of cylinder bores may differ from cylinder to cylinder. Grade number on cylinder block deck surface, next to each cylinder bore, represents standard diameter of cylinder. If installing standard diameter pistons, ensure grade number on top of piston matches cylinder bore grade number.
  3. If cylinder bore diameter, maximum taper or maximum out-of-round exceed specification, bore all cylinders and install oversize pistons. Before boring, install main bearing caps and tighten bolts to specification to prevent cylinder distortion. See TORQUE SPECIFICATIONS  .
