I had a fairly extensive thread on RRORC.com discussing why it was happening. This is the procedure and what we came up with.
I ended up filling it till it came out of the fill hole (which is the original vent location) and putting a catch on it to monitor the fluid loss. I lost almost a full 16oz bottle before the fluid stopped coming out of the vent. That's half a quart.
I know it took a tad over 2 quarts to fill it from MY fill location. Guys on rrorc that have the doubler said it takes about 1 quart to fill it from the stock fill location. With those figures, I have 50% more fluid in my case than what there would be stock. I'm happy with that.
The general consensus was I was overfilling it, and the fluid would aerate to the point that it would push the fluid out of the vent line. I eventually lost enough fluid that the aeration wasn't enough for it to fill the case when it expanded.
Since it stopped leaking, I removed the catch. After driving it a couple days, I noticed I was losing fluid again (oil spots on the tailgate, drop hanging from the vent line, etc). So I put the catch back on. I don't lose fluid with the catch. I lose fluid without it. This tells me that the wind may be a factor, causing a low pressure that pulls the fluid out somehow. I've just been running it with the catch on it until I re-route the vent to a 'less windy' location. Haven't lost a drop since I re-installed the catch.
Sooo I guess it's not 100% solved yet, but I think I've about got it taken care of.
