Rebuilt k27 7006 f$&@ed

I have installed my rebuilt k27 and have oil pushing out through both sides, turbine into the exhaust and compressor into the intercooler. There was an oil slick on the garage floor 3 foot plus long from the exhaust and new clean oil leaking back down from the intercooler.
I tested the scavenge pump and it appeared to be fine as it was pumping oil well when tested. I spoke to the rebuilder and they want a compression test for some reason yet the engine starts fine and does not run rough it is running on all six. My mechanic said there is nothing wrong with the compression. So even if there was a hole in a piston or oil getting past the rings it could not pump this much oil into the exhaust.
The rebuilder has said it is unlikely to have both seals fail, my mechanic feels it's the turbo.
Any other ideas would be appreciated before I remove the turbo again. At least it will be a lot easier to remove this time as I only ran it for 5 to 10 minutes and did not drive it.
