It's a tic-a-tac-a-tic-a-tac-a noise if they're loose.

It could be something simple. Mine did something similar and it turned out that the bonnet prop was rattling once the engine hit a certain frequency.
Just put bit of rubber around it.
Something to check if it sounds like metal on metal.

You will have to give into slightly. That said, you might completely overcome this, just don’t hold your poor mini to it if you don’t :-/

I've had the bonnet prop and exhaust clamp (didnt rattle all of the time) come loose before also. Start it up with the bonnet open and see if it makes the noise at 2.5k (once warm).
I believe some also had heat shields fitted (maybe just the MPI?) so might be that (if its got one)?

You sure the rattle comes from the engine? I had rattle a year ago and it was the catalytic converter after my JDM coil failed and gasoline went straight to the cat and damaged it.

Without knowing exactly how the rattle sound there is only one thing to check details in the engine bay. I started out to control major bolts and nuts such as donuts in front where maybe the shims are missing, Engine steadies rubbers and metal tubes inside the rubbers, radiator, horn, relais and so on.
I had a terrible time to find it,
If you can hear it when the engine idles you shoul find it listening to the engine with an open bonnet.

Does it happen only at certain RPMs? If so, will it make it parked up with the car revving to that RPM? Get a length of tube and hold it to your ear and start poking around in the engine bay. Really helps isolate noises.
