I took the stock oil lines off with the turbo still bolted up, and I would absolutely never do it again. It took me somewhere near 6 hours of goofing around. Then when I went to put the braided lines I bought from DM on, I found out they wouldn't fit without loosening the turbo to manifold bolts. I hobjobbed it and fixed it months later.
DON'T HOBJOB IT. DO IT RIGHT. Once you learn how to take the braided line off and put it back on it's pretty simple but it won't just 'go on' without finangling for a bit, you'll learn how to position it after the first try though. Takes less than two minutes to take it off/put it back on once you know what to look for.
