So with a ring compressor you cannot compress them enough? I am confused
do you have a ring compressor?
If you remove the metal outer rings do they fit in block flat alone? What is your ring end gap?
is this how you installed them?https://www.google.com/search?q=oil+control+ring+installation&espv=2&biw=1366&bih=638&tbm=isch&imgil=BSbxz94xgKOreM%253A%253BUONXpWVwpy_EGM%253Bhttp%25253A%25252F%25252Fwww.autozone.com%25252Frepairinfo%25252Fcommon%25252FrepairInfoMain.jsp%25253FtargetPage%2525253DproductsHowToInspect%25252526leftNavPage%2525253DproductsHowTo%25252526pageId%2525253D%25252525090996b43f80a01484%25252526subtitle%2525253Dreplace&source=iu&pf=m&fir=BSbxz94xgKOreM%253A%252CUONXpWVwpy_EGM%252C_&usg=__u0OxHFfBDEpFqBao1pE0ICRGCdE%3D&ved=0ahUKEwjQr7vD7tzPAhUGWSYKHV5OBzEQyjcITg&ei=GigCWNC6IIaymQHenJ2IAw#imgrc=2pLW4mvyUIw2DM%3A
You didn't answer my question. Are you using a ring compressor? yes you can send pic
have you fitted the rings on the cylinder and measured ring end gap?
Remove ring and fit in cylinder without piston. My immediate suspicion is that your oil groove needs to be cleaned. I would suggest soaking the pistons in some strong cleaner.
