The seal was installed correctly, and the oil was being slung out by the front of the flywheel. I checked the cam retainer both times and it didn't look like the problem. The engine has PCV and a vented cap. No oil was blown out of the cap onto the valve cover. The engine is dry including the pan. It was just leaking out at the flywheel cover.
I'll reinstall this week and hopefully it's fixed.
