Didn't notice this thread was still alive. I've been trying to close out the threads i've started with what I did to solve the problem but I forgot about this one. It ended up being bad orings on the oil thermostat housing, where the lines go into the housing(picture 2 on my imgur link). Needed 3 seals(2 orings for the lines, one rectangular-ish one for where the Tstat housing meets the oil pan) Make sure the orings and the area where the orings are going is clean of any debris. The hardest part was getting the rectangular seal to stay in place. If i remember right the oring was rectangular, but the groove where it sat had some sort of notches that made it hard for the seal to stay in. I thought I got it so many times, just to feel around the area and feel the seal had slipped out while i tightened it. To make matters worse, it kept falling on the ground and picking up debris, so I had to keep cleaning it thoroughly. I ended up using a little liquid silicone gasket in the groove to get it to stick in place while I was tightening it down, and after a few tries with that it ended up going in...no more leak.
I haven't stuck my head under there since I did it, but I don't see any oil on the ground. It got to the point where I was losing over a quart a day, a decent oil puddle would form any time I was idling in place. This job is cheap if you do it on your own, even using genuine volvo seals(less than $5 if i remember correctly), but it can get frustrating if you don't take your time to do it right.

Imgur link I was referring to. Second pic down is where the leak was coming from.
