engine would pump oil.
Look at these ring side views...it's about 2/3rds down..

This is taken from the original post.
Of the two remaining compression rings, one has no camfer or bevel on it and no identification on either side. Instructions say it can install with either side up.
If it has no Chamfer ,Bevel or outside scraper design to scrape oil and can be installed with either side up then it is probably a second compression ring
with a rectangular cross section.
I agree the more modern second groove rings have a outside scraper design to scrape oil down and must be installed with the scraper edge down.
But they still serve as a second compression ring as well as an oil scraper ring.
Not trying to argue but I have to agree with the manufacturer.
