oil in my intake, bad piston rings? bad valve seals?

Do a compression test before you get too worried. Doing a dry then a "wet" compression test will give you a rough idea if it's rings, stem seals or even a head gasket problem.
The best scenario would be an overfilled crankcase: 16Vs are really sensitive to oil fill level, and have a way of "puking" oil out the breather into the intake if even slightly overfilled.
Hoping for the best...

i think its pretty normal if you just have a tad. but if there is a puddle or the sides are soaked. then you may have a problem.

back from the dead after 10 years :laugh:. Im having the same problem with my aba 16v. The engine was freshly rebuild top to bottom and i have put about 4k on it since. The engine doesn't smoke at all (or at least not noticeble) but im having to top off the oil about 1 litre every 600km. So today i took the intake off and sure enough the walls on the bottom intake where covered in oil. Anyone know if this is a head or bottoms end problem?

Have you done a compression test? Dry and wet. Do you have a catch can for crankcase ventilation, Or is that still hooked up to intake?
