My shiny new 2013 WRX Base 5-Door went in for its first oil change at about 1,100 miles, and to my surprise the dealer found an oil leak coming from the Turbo Oil Outlet Tube (part #4 on the attached illustration). It's a slow leak, but still needs to be addressed. What surprised me is that this part was not in stock, leading me to believe that this sort of leak is pretty rare. The part is coming in and will be installed this week.
Just out of curiosity, has anyone else encountered this problem?
