big thanks to this guy for helping me out, the tool he made worked on the first try. got the CPV o-ring and primary o2 sensors replaced this morning. check the garage floor for leaks over the next week, then hopefully it'll be about time to put the EC7s and super sports back on.

as others have mentioned, put a little pressure on the old ring trying to get it off and it just shattered into pieces. Herman the German could've done a better job with this little system.
