The piston rings placement on the piston is crucial to proper compression and oil distribution.

•    Top Ring if it has writing usually will have a 1 and or a single letter that needs face visible top. The top ring is usually polished as well.

•    2nd Ring if it has written will usually have 2 and or a letter or pair of letters that need also a face visible top.

•    Expanding Ring is the wavy ring on the inside with the two thin flat smooth Side Rings on the top and bottom. They make a group called the Oil Rings.
