So the marker started leaking out through the back, and started shooting extremely hot. I turned the velocity all the way down and it made no difference.
I ended up bringing it to the Tippmann booth at Wasaga this past weekend. After the first unsuccessful repair, they ended up swapping in a new FlexValve assembly. No more chops in the breach/chamber, leaks, and velocity issues. Had some barrel breaks on full auto, but that's probably because of crappy paint and weather.
