Oil Drain (Turbo)
 

New gasket, bolts are tight, surfaces were clean before assembly, still got a drip. :argh:

I hope I don't have a cracked flange on the turbo side. :s:

I would probably try replacing the tube itself next.

IIRC, its got a flange on it? Could that be distorted and not sealing correctly?

Could be, it wouldn't take much to remove the tube (just hope the o-rings aren't a weird size) and look at it.
