Power steering leak on my 5000

[fatchance]

Hey folks,

So I'm having a leak out the air vent on the top of my power steering pump. Any have this happen? Before I crack it open wanted to see if I could get any advice. Is there a seal/filter to keep liquid in but allow air out that needs replacing?

I have a picture but dont know how to post it.

Thanks.

Replaced the whole air vent piece from a space pump I have. Solved my problem. The gasket on the old one seemed to be in the same condition as the other one though so not sure why this has made a difference. But it doesn't leak so who cares!
