You likely have the same leak as I do on one of the AlfaBill fleet. It's 
not the oil sender, it's possibly, likely the head gasket about 2/3 back on 
the front head, there's an oil passage close to the edge and mine has the 
tiniest little trickle that pools up after a while. It can be a hazard in 
left turns when the puddle flows over the water pump area and does a 
misting when it hits the belts.

Mine is so minor that I keep it clean and I'm waiting for another excuse to 
pull the head on an otherwise sweet running car. This leak stumped 2 
different shops. At the shock of others purer than I, I have a piece of 
"absorbent  material" deftly placed to catch the minor flow forward. It's 
more annoyance than anything else. It hasn't gotten worse in 11,000 miles.

YMMV....
