Massive Oil Leak

[thebenstenator]

So my car ('92 300D) leaked about 5-6 quarts of oil in the last month or so. Here's a video of the drippage.

Pretty insane. I know.

Any ideas where it might be coming from? The video shows just below the IP. It's dripping onto the motor mount. That's the fuel thermostat (or whatever it's called) in the picture as well.

Also, I'm not sure how the oil pressure gauge in the car is suppose to read. But as of right now it will go up to 3 while I'm accelerating and it will drop with each gear shift to around 1-2 (exactly in time with the rpm's) until I reach a steady speed it will drop to 0 or just above 0.
