Connecting Rod Large End Bore

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

Tighten the bolts to specification, then measure the bore in 2 directions. The difference is the connecting rod bore out-of-round. Verify the out-of-round is within specification.
- Refer to the appropriate ENGINE article for the procedure.
- If out of specification, install new components as necessary. Refer to the appropriate ENGINE article for the procedure.
