TOTAL SEAL RING GAPS AND GAPLESS THEORY

TOP RINGS

        Conventional top rings with conventional second rings should be about .012�. (.0035� per inch).  

         Conventional top with Gapless 2nd ring sets should be around .020�.   This wider gap is needed because pressure builds up between conventional top and gapless 2nd on the power stroke.  This pressure needs to vent after BDC of the power stroke or it will unseal the top ring in the next cycle.  

        Gapless top rings heat up more than conventional and requires about .020" end gap to allow for expansion

SECOND RINGS.
