    S6 oil supply leaking

    I've tightened the oil supply to the turbo 4 times with new gaskets and I've even tried sealant but it keeps leaking oil. When I take the oil supply off the oil keeps coming out of the supple pipe and there is oil in the turbo, it's not draining.
    could it be the turbo or should I try a different drain hose?

    If it were me, based on that info, I would want to check the turbo oil return (to the block) line. If it is plugged, there would be considerable pressure on the oil feed line connection.

      I've taken the oil return off and it's not blocked. I also took the turbo off so I can take it to the guy that built it for me. It's a brand new RS2 thats never been used, maybe there's something wrong with the bearing housing

        Have you checked the feed line flange for flatness?
