Re:check the PCV check valve too.

Under boost, the PCV check valve prevents the positive pressure from pressurizing the crankcase. If the check-valve fails, the positive pressure in the crankcase can prevent the turbo from draining properly back into the oil pan. If that happens, the oil-level within the turbo gets too high and leaks into the compressor side. Then it's sucked into the intake manifold. I'm curious how many miles are on your turbocharger? Mine was replaced and I know the radiator was removed but not the front-end. It's an odd setup as the turbo is part of the exhaust manifold. Garrett turbo GT-1549 I think?
