Hey so the banjo fitting leading to the top of my turbo is leaking oil at the block. Does anyone know where to find a good diagram of the turbo for 2011 WRX? I'm trying to figure out if there is an oil return line from the turbo back to the engine block and whether or not there is a screen filter in a banjo fitting bolt on these later year WRX's. I found the line leading from the engine to the turbo and the two coolant lines going in and out of the turbo but I can't see a return hose for the oil going to the turbo back to the engine block.
Any suggestions would be a big help!
