No need to replace the piston. You do need to replace the rings and have a new cylinder liners pressed in. The cylinder liner is a high wear item which over time and age will become 'ovalish' shape.

About 10 yrs ago, we rebuilt our 300D engine. Had the cylinders honed by a machine shop and put new rings on the pistons that were one size larger. Car was awesome after re-installation, lot more power/torque. Drove it for another 6yrs before selling.
