I thought about tightening it up, but I can't find/see where to tighten it up. I see a big square nut on the injector side - the other side is where I can't find anything, and I don't know the torque needed. I don't know about this, I'm beginning to see this might be way over my head. Anybody know what a shop would charge to change the seal? When I was looking at my oil pan I called the Mercedes dealership in Bowling Green and they said $600. I called a shop in Nashville, and they said $900. Anyway, thanks for the comments.

Happy New Year,
