1990 Volvo 740 GL
Suddenly it has started leaking oil from the underside. I believe it is dripping down to where the spot in the video is. This part connects to belts. I can easily move it. Not sure what the problem is, or if im diagnosing the source correctly.

Any help would be appreciated!

You'll likely need to clean it up some and check it again. It looks like the oil is everywhere under there. You may have a crankshaft seal or camshaft seal that has lost it grip.
