When the 3.6 was in my V8 there was a persistent oil leak that kept the lower 
block awash in oil. After going through the usual culprits of oil senders, 
and valve cover gaskets, a wash down of the block and a black light found the 
culprit to be the upper oil pan gasket. It cost a bit but I had both the 
lower and upper oil pan gaskets replaced and the oil leak was cured. 

You're probably going to have to use a black light to track the leak source if 
you've looked at the usual places.
