It seems as though most people believe that the water got there from water vapor condensing in the intercooler being recirculated from my Radium catch can. Most people are also saying the oil treated air filter would not have allowed that much water to enter the air filter through it.
So my conclusion is to modify my PCV catch can, and instead of it recirculating back into my intake, put a small filter on the exit of the catch can and make it vent to atmosphere.
Radium said this to me: "Condensation contamination is normal with all internal combustion engines. In fact, it is one of the reasons engine oil needs frequent changing. However, the catch can(s) should be collecting the majority of this water vapor."
Obviously I can't prove how the water got there either way, other than waiting to see if the problem occurs again after making a change to my system.
But there are enough smart people commenting in this thread (and getting frustrated with my constant posting) that suggest the same thing. So it's worth going with that solution.
A vented catch can is bad for emission reasons because you are venting the harmful gasses directly into the air as opposed to directing them back into your intake stream to be burnt. That's why strict emissions states would fail you if they see a vented system. That's a no no for the EPA. That's what I was trying to avoid with the Radium setup.
But a vented setup is the best way to go for performance.
