Why is it doing this? Is it overfull?

Should I install a breather tank? Just remove the vent and put a different fitting in the case plumbed to a catch can? Should I do it in -4an or -6an line?
Any particular catch can yall would recommend?
I found this one earlier...

Any other suggestions?
Thanks beer



Next time it’s apart, use a A518 overdrive retainer gasket cut down, and punched for the holes, between the output shaft support and the case. Hot cross leak from the return flow, charging the vent cavity. You’re welcome.
