Don't you know...gapless top rings don't deal. They are all oil burners. That means they are junk.
Now that we dispensed with that, I've use probably a hundred sets of gapless top rings. In everything from street cars, to street/strip junk, bracket engines and some heads up stuff.
Not one of them has ever had a oil using issue. Not one. The shop I was at when we tested them still uses them. Every day. He still has had an oil user come back.
I would think if the benefits such as increased mileage/power/emissions even in a minute amount existed with just a gapless ring design, you would find them in every OEM application around the globe. J.Rob
