I didn't think it had anything to do with the oil change until it started again today and realized I had just changed the oil, just like before. Could be completely unrelated but that's the only additional variable to how I've been treating it since. I've driven it long and hard without problems, changed the oil and drive easy and its back. I don't know though.
I'm 99% sure the rings were seated properly and if they don't unseat then I guess it's not a ring issue. I oiled the cylinder walls and the skirt when assembling.
I'm going to try to get a camera underneath while driving tomorrow which should help tell if it's the valve seals or not, but those aren't too old.
