What brand filters do you run
Generally WIX or Napa. Sometimes AC Delco. But this filter was a FRAM Tough guard filter from back before I started hearing ugly stories about the cheapies. The new one is WIX.
I've looked at the old filter, and could easily be convinced that the plug came out of the center of it. But I have no idea how it would have gotten to the outer side, nor how it would have found the check valve.
The check valve cycles like I would have expected it to do, so I finished up the oil change and am planning on putting 1300 miles on it this weekend. We'll see how things turn out.
