while changing my oil, I noted a film of oil on a vertical rubber tube on the underside of the engine which connects to a metal tube with a small clamp, the metal tube then connecting to a large metal housing behind it. It looks like part of the dry sump system. I have never noted oil on the top side of the belly pan or on the garage floor. Its almost like it was weeping minimally. Was wondering if this was just a loose clamp issue or? Dont want to mess with this unless I know what I am messing with
The pics attached are taken from the underside of the car looking up. For orientation I have labelled the bow(front) and stern (back of the bus

 

Check out the blown up Aston parts diagrams on the Scuderia web site....model specific and very helpful.

 

Doesn't look to be part of the oiling system, as best I can tell.

 

Air/oil separator drain tube back to the crankcase. Its a plastic tube and if you fiddle with it may really start leaking. Look up AOS valve about the O-ring leaking.

 

thanks J DoubleU, thats it
