Recently bought an sfs 3 inch tip to fit to my lcr, been having a quick look/ feel around the engine bay to see how easy fitting would be. After putting my hand on the underside of the turbo, there seemed to be a bit of oil gathering on the bottom of the unit. As it was getting dark I couldnt really get a proper look around it, does anybody have an idea as to what may be causing this? Any info would be greatly appreciated.
