Hi everyone! I am new to the saabforum and was hoping someone could help me out. I have a 2004 Saab 9-3 2.0t and it has a small oil leak. It seems like it is coming from this nut behind the engine, under a hose that goes to the firewall. I have a few pictures that should help explain the problem better. I've tried tightening the nut but that didn't seem to help. Any help would be greatly appreciated.

that last picture was just supposed to show the oil collecting in there, sorry it's a little hard to see that one

Thank you, Alex
