Cylinder Block

WARNING: This page is about a different car, the 1995 Jeep Wrangler and 1994 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.
  1. Measure cylinder bore diameter crosswise to cylinder block near top of bore. Repeat measurement at bottom of bore. Subtract smaller diameter from larger diameter to determine taper. Repeat measurements for each cylinder.
  2. Repeat measurements with measuring device rotated 120 degrees. Repeat this step for a total of 3 measurements. Cylinder out-of-round is the difference between measurements. Repeat for each cylinder.
  3. Bore and hone cylinders for oversize pistons if taper or out-of-round exceeds specification. Move hone up and down to provide a 60-degree crosshatch pattern. DO NOT  use a rigid hone. Refer to CYLINDER BLOCK  table under ENGINE SPECIFICATIONS.
