WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
- Measure the cylinder bore at the top, middle and bottom of piston ring travel in 2 directions as indicated in Fig 1. Verify the cylinder bore is within the wear limit. The difference indicates the cylinder bore taper. Bore the cylinder to the next oversize limit.
- Refer to appropriate ENGINE article for the procedure.
