Blown fork seal

Hm, well my Expedition model blew a seal about two weeks ago. I thought it might work itself out but it didn't.

I tried a piece cut off at 2 l soda bottle that went up there seemingly but didn't do the job. Then I tried a fork seal tool.

You have to pop the dust seal off to make it work but it seemed to do the job. I noticed that I was cleaning it that almost immediately there was air pressure. I'm thinking that's why the seal actually blew out because it's pretty well covered.

The bike has 12k miles. I have previous experience with SuMo racing and commonly with WP forks you want to have the air pressure release valves on the forks. It was a factory accessory at the time but I'm sure there's others. It's a very simple spring loaded pressure release. There are T20 screws already there but not seeing that one in my tool kit.

Is anyone else having issue with the fork seals pumping up?
