The whole OEM CCV system is eliminated with the TS supercharger. It replaces the stock manifold. All there is, is one hose from the valve cover to the PCV valve on top the the supercharger manifold. My bet would be that PCV valve got frozen. That PCV valve is a BMW part but I don't know the part number.
My car had mayo in that PCV valve and it's been down here its whole life. Michele, I'd consider getting an oil catch can. That's the route I'm going to take. I already had one in it but the baffling wasn't good enough. It's gotta have good baffling
