Reviving the Cheapest RS4 from Bring a Trailer

That leak on the right side near the water pump could also be the oil filter housing gasket.

The oil passes down the valley through under the intake manifold and drips in invisible areas from the front of the engine down to that area. In my case a new number 8 oil filter housing gasket fixed that leak. peek through the I/m with a flashlight on the drivers side and you will see if there is oil on that side of the valley. I/m has lots of flashlight openings to check to see if yours is coming from there. I've changed lots of seals though, so yours might be another one. The oil leaks never end... lol

Intake manifold.

Gotcha.
I spend the weekend under the car with degreaser and a brushes to remove everything. Hopefully this will aid the search.
