  1. Check the cylinder condition. Some light vertical marks may be visible on the cylinder wall. In these areas, check that the honing marks are still visible in this marked area. If they are, the cylinder surface has not been compromised and the engine block can be used.
  2. Measure the cylinder bore diameter 37 mm (1.457 in) from the deck face using the EN-8087  gauge.
  3. Compare your results with the Engine Mechanical Specifications (LAF, LEA, or LUK) . If the cylinder diameter exceeds the specifications, replace the engine block.
