Cylinder Bore Taper: Notes
WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
- Measure the cylinder bore with an internal micrometer.
- Carry out the measurements in different directions and at different heights to determine if there is any out-of-roundness or tapering.
- If the measurement is out of the specified range, install a new block or hone out the cylinder block (if applicable/allowed).
NOTE:
The main bearing caps or lower crankcase must be in place and tightened to the specified torque; however, the bearing shells should not be installed.
