Connecting Rod Large End Bore

NOTE: Refer to the appropriate ENGINE MECHANICAL - 3.5L article or ENGINE MECHANICAL - 3.5L GTDI article 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.
