Assembling short block tomorrow. When checking the delivered piston rings for accurate measures I noticed this stepped slot in the second compression ring groove. When I pulled the engine apart I just discarded the old rings. I never noticed this "step" in the groove. I never recalled seeing this type of piston before. The second ring groove and second compression ring are correct for size but (why) would the bottom half be open? Just wondering.
