Oil leak above front differential

I noticed a pretty sizeable oil leak that seemed to originate on the driver's side just above the front differential. I replaced the oil pipe O-rings that feed into the adapter with thermostat to the engine block and no change. Please see the pictures's a difficult area to access and picture with the differential in. The last picture is from realoem and is labeled "adapter with thermostat." It looks like the leak is coming from on this unit or where it mounts to the engine block. There is indeed an O-ring that fits between this unit and the block. Does anyone have experience replacing this or is it known to fail? Thanks a lot
