One of the main and crucial areas of rebuilding an engine is to recondition the connecting rods. There are many different types of connecting rods from cast steel to powdered metal “cracked” rods to all the various types of performance rods. The processes used to recondition this engine component may vary a little from one rebuilder to the next, but the end goal is always the same – straight rods with round bores. Sounds simple, but like anything worth doing, there’s always more to it than you think.
