From the top of the engine on a cooper S

Sounds like a diesel and if I take the oil filler cap off the noise increases making it obvious it's coming from within

The noise reminds me of an old cortina with a shot Cam

Any thoughts?

Slapping cam chain with possible broken guides would be a guess.

They sound terrible when they fail.
If one of the guides snap, especially the guide between the cam sprockets they sound like it's the end of the world.
