Connecting Rod - Large End Bore

Tighten the bolts to specification, then measure the bore in two directions. The difference is the connecting rod bore out-of-round. Verify the out-of-round is within specification.
- Refer to SYSTEM & COMPONENT TESTING - GASOLINE for the procedure.
- If out of specification, install new components as necessary. Refer to REMOVAL & INSTALLATION - BLACKWOOD, EXPEDITION, F150 PICKUP & NAVIGATOR - GASOLINE for the procedure.
