Hi guys, and thanks in advance for reading this.

I recently bought a Volvo S60 2.4 NA (12/2001), and soon realized I had an oil leak. Under normal driving there are no issues, but as soon as I put a bit of pressure on the engine, it "sprays" out oil on the exhaust/exhaust manifold. It's hard to see from under the car where it's coming from, but at first glance it doesn't seem to be the head gasket as it looks dry in that area.
I've tried to rev the engine myself and it starts smoking like crazy, but it's impossible to make it under the car before it stops spraying and smoking. I'll get someone to help me of course, but do any of you have an idea? What could it be?

I'll include a short clip that shows the severity of the smoking:

Thanks you, I hope someone has an idea.
