      Rear main seal walked out

      Good Day,

      I have decided to finally fix my oil leak on my 2004 Aveo Automatic with 280,xxx KM. I removed the transmission and found the seal was rubbing on the flex plate. It cut about half way through the plate. I have a replacement now but I'm worried about it happening again. It was leaking oil from the valve cover and rear main when I bought it. I did the valve cover and it stopped. I did a dye test to confirm the rear main was leaking (before putting myself through this torture) and the valve cover has a very very small leak again. I confirmed that it had no cracks when it was off. Back to the main issue the previous owner thought they were a "mechanic" I've mainly had to redo repairs they did previously to make it proper. I hope they overfilled the oil and that was the initial cause. But if it's not what should I be going over? So far feedback has been to confirm my PCV valve is working (due to me using stop leak previously) and to do a compression leak down test. Anyone encounter this issue before? Any help or feedback will be appreciated. Thank you

      Photos of the Flex Plate. It feels much worse then it looks. Took off at least 1/16"
