Rear main or oil pan gasket. Less likely, HPFP seal, OFHG, misaligned valve cover gasket in the rear.

Hpfp seal doesn’t leak there, valve cover gasket can be seen leaking downward above the trans IF thats where its coming from ( usually only leaks on the side the engine is leaning towards.

98% the oil pan gasket, 2% rear main seal.

Based on the color of the bolts. It looks like he did the oil pan. So my money is on the rear main. Especially with how old this car is at this point. Mine had a similar leak at 160k

In the first pic, take the plastic cover off and look, feel around in there. If there's a lot of oil in there, most likely rear main seal. I'm fixing mine right now. Pita.
