Well I ran the turbo this morning without the compressor housing and the drain line disconnected from the turbo and I just let it drain into a bucket. So I started it up and revved it up top full boost and it leaked like it did before. Then I revved it to full boost again and it stopped leading and did not leak the 2 times I revved it again after it stopped leaking. I bought new an fittings and I'll try to run a better drain line when I get back home on tuesday. Ago I'm pretty confident it was just that drain line. I can't explain why it leaked for the first couple of revs though without any drain restriction...
