I have Goetze piston rings for an M20 and I am confused on the oil ring expander's (or waffle ring's) diameter. It seems to be too big resulting in no end gap. I have not had to file down any of the other compression or scraper rings as they were set correctly at .4mm (end gap) from the factory box.... Does anyone have a write up and/or pictures of any three piece oil ring installed on a piston? Thanks
