While installing an uppipe my son and his friends inadvertantly pulled out the oil return line and of course didn't realized it until there was a puddle of oil on the floor. Late at night they were unable to get the line on and trashed it. Do we have to get a new one from a Subaru dealer or is there a particular high heat reinforced hose that we can get from an auto parts store and cut to length? If so, what are the inside and outside diameters of this hose, what type is it, and how long is it? Also, I have read that it is almost impossible to get this hose on without pulling the turbo first. Is this correct?
