Water Intrusion in Bumpstop

Long story short: I was installing my ACOS spacers today, and when I pulled the bumpstop , it was like pulling the drain plug out of a boat. Drivers side was fine, but the passenger side in in question. Tomorrow, I plan on looking for the pathway that the water followed, but does anyone have any experience with this? I did some searches, but only came up with one unanswered post.

Ac drain points into the frame rail on the right side.

Exit path for the water is probably blocked

I should have looked before posting... on the passenger side, there is an opening under the coolant bottle. Used some silicone and on the drivers side, some plugs. Should be all set now, but I will keep an eye on it.

Years ago, I found water in both ACOSs, the result from underwood washing.
Not wanting rust to form, drain holes were drilled in each ACOS, to drain any water that gets inside.
JKS should've provided drains, in the original design.
