Oil leaks on the N54 twin turbo can come from a number of places and the oil lines to the turbos are one of more likely. Usually it's the o-rings where the line attaches to the turbo housing. But in some cases a leak remains even after replacing the turbo oil line seals and in those cases it's probably the line itself. BMW uses a braided stainless steel line with metal ends crimped on and leaks develop from inside the crimps. The most cost effective fix is to replace the leaking N54 oil lines with new factory lines.

Another reason to replace the N54 turbo oil lines is that the lines can become plugged and restricted by burnt oil residue, causing the turbochargers to overheat and fail.  If you're replacing your turbos, we recommend replacing the oil supply/return lines while you're in there.

The supply and return lines can also become kinked during the turbocharger removal process.  If you suspect that your lines have been bent or damaged, it is wise to replace them preventively.
