But my question is in a 15 year old car does the piston actually wear out/break and need replacing so as to prevent damage? Is it designed to last 15-20-30+ years?
Thanks,

The piston doesn't wear out, but the original is more prone to jamming in the bore, leading loss of pressure than the updated replacement. The question is whether the piston jams in the bore, resulting in bearing damage, etc., or if debris going through the oil pump and through the oil pressure regulator (relief piston), causes it to stick.
