I have a 2010 mini with a r56. the loss of power light comes on when I step on it. I know the PCV valve is bad on it and can set this light. I also have a rear main seal leak so the turbo has to come of, 160k miles on it and has a ticking noise should I while it's off replace it or does the turbo make any noise already? Another route is turbo rebuild and clean. Possibility? And any video of pulling the r56 for reference would be helpful I've been looking online there is not a lot of help in that Era of mini.
