While replacing the air filter bracket on my 300d, I unbolted the turbo oil supply line and noticed that there isn't a gasket installed between the two surfaces. I thought there was supposed to be a gasket. I ordered one from the local mb dealer but it doesn't fit - it's slightly too large and I think is the turbo's oil return line gasket.

Can someone confirm that the turbo's oil supply line should have a gasket installed? Is this it?
