BUICK ENGINE KNOCK

Im Hearing A Lound Knocking Sound In My Car As I Drive.I Was Told That Its A Rod Knocking.I Was Wondering Would Rebuilding Be The Best Idea...

I Have A Knocking Coming From The Motor When You Crack It And When You Take Off. It Quiets Down When You Get Up To Speed.

My Car Makes A Knocking Noise When Idling But Disappears When Accelerating But Otherwise Drives Fine
