i wouldnt take the turbo off. thats a lot of work and a few other gaskets for just a little one. just completely remove the return line, clean it up real good, go get some gasket paper sheets, cut 2 new gaskets, put a lite coat of RTV on them and reinstall. wait at least 4 hours before driving the car so the RTV can harden.
Edit: a floor jack and set of jack stands should be more then enough.
