WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, and 2012 Ford F450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Refer to the appropriate ENGINE article service information for the specification.

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.
