P/S reservoir cap leak?!?!

[Milspec180]

Ok so i replaced my steering rack and p/s pump recently and attended a drift event this weekend. I still have old stock hoses and no p/s cooler but even after 3 runs my reservoir seems to be blowing atf fluid all over my engine bay. I have modded knuckles and angle kit so there is some stress on my system. Anyone else have this problem? Any help would be appreciated! Thanks in advance!

It's leaking in air like said above and all the fluid gets foamy and expands fast and leaks out.i bet your power steering pump is noisy once hot huh?check all your lines/fittings for any p/s leaks.if you have any leak then I'm sure that your air leak as well
