WHICH WAY IS UP
When you are not sure which way the 2nd rings go in or cannot figure out the markings, remember, they are oil scrapers and have a tapered face. I hold one down to see which way it leans vs. a square. The side that leans towards the square is the top and is quite evident. This is a good test that I learned from a Top Ring Manufacturer and felt it is worth repeating. I had a customer who assembled his engine and brought it in as a Dyno Job only. It blew oil out the headers and upon disassembly we found all the 2nd rings were in upside down. They scraped the oil into the combustion chambers!
