[V6-12v] oil leaks driving me nuts....

Patient is 1995 A6Q Sedan standard, with 220k miles.
I am getting a persistent oil leak(s) in the valley between the cylinder
banks. I have replaced the valley pan gasket and have also RTV'd the valve
cover gaskets temporarily as I am planning on buying replacements, but
wanted to be sure of my leak source 1st. I thought I read somewhere
something about the 12V head gaskets sometimes being prone to leaking oil
and water. Which would explain the reason I have to add water every once in
a while.. Will a compression test show if there is a problem? Car runs
great, just has a highly annoying burning oil smell that I really want to be
I know there are also places on the rear of the heads that can leak, but
that doesn't explain oil accumulating in the valley after I replaced the
valley gasket. Not to mention, valve cover gaskets should leak on the down
side, not on the upper side. Head gaskets though, since its under
compression, I could see them leaking upwards.
Anyone got any thoughts or suggestions?
