Update for anyone interested- I made a couple changed. First I replaced the Verus Oil Return Line with a braided Nylon line that doesn't bend like the one they provide. Second, I added a WRX PCV valve and used the stock hose to route it to the AOS. Third, I separated the two VTA hoses and kept them as two hoses. Before, I used a Y Pipe to turn the two hoses into one VTA hose. I took the car to the track with this set up. There was still a small amount of leakage but not nearly as much as before. I attribute this mainly to the reinstallation of a PCV valve. The problem definitely isn't solved, but at least this is a start and I can track like this. I may try a different AOS to see if that provides a long term solution.
