The oil ring is 3 piece but not the flex vent that is popular but it does use the same rails as the flex vent.If there is room the groove could be widened to 3/16" as there is a oil set that is produced in flex vent that could work if the groove depth were the same.The conventional flex vent 3 piece uses a #860 spacer,and the spacer in the 5/32 set isn't the same as a standard flex vent,but it is 3 piece.
