Tech Feature: Reasons for Piston Replacement
Though pistons can often be salvaged when rebuilding or remanufacturing an engine, sometimes they have to be replaced. The original pistons may have worn or damaged ring grooves, wrist pins or skirts, or they may have cracks. New pistons may also be necessary if the cylinders have too much taper wear and the block has to be bored to oversize. Or, maybe you just don’t want to reuse the original pistons if you’re building a performance engine or a high load engine like a diesel light-duty pickup truck.
