Measuring Cylinder Bore Diameter

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
  1. Measure the cylinder bore diameter 37 mm (47 in) from the deck face using a cylinder bore micrometer.
  2. Compare your results with the Engine Mechanical Specifications . If the cylinder diameter exceeds the specifications, the cylinder block must be replaced. There are no oversized pistons and rings available for service.
