Fix or replace oil pan on A6 Avant Quattro

[David Kase]

I would bite the bullet and get a replacement and be done with it.  An 
area that has constant oil coming through the crack will be next to 
impossible to fix.  The only real repair is welding and you will not 
have a good weld without removing the pan and cleaning the inside.  Plus 
the crack goes up to the drain plug which would be affected by the weld.
Sure you can use some sealer or other hokey aluminum filler but it 
-will- leak again.  Gotta get a new pan my man...
