take it out, clean it, wire brush it, degrease it, and the inner threads.

Maybe you can use a bit of plumbers tape since it seems to be gaps around the thread?

Anything to do the breather being blocked? Excess pressure and all!

I always put some ptfe tape on all drain/filler plugs. Replace it everytime and never had one leak yet.
Shame you cant wrap it around the engine, gearbox, transfer box, front axle...................
