That's good.
Still worth looking at as i have seen the bolts come loose.

If it was not new those two piece pulleys have an inner rubber vibration absorbing ring and they do crack and go bad.
If it is the pulley i would look immediately as you don't want to end up with a damaged crank end.

Drove to work today and it hasn't made the noise! I like the idea of just checking to see if the water pump and alt spin freely. While I am there, I will have a look at the pulley. I changed the original Rover Mini pulley to the "S" 2-piece pulley...and had it balanced prior to install. Being that its 2-piece, I'll confirm its stall all tight.

If I get it to make the sound again, I will try to removed the belt and see if it continues. That would rule or confirm a lot.

Also look at your crankshaft pulley to see if it is coming loose and maybe hitting the lower radiator bracket, personally i can't see that much noise coming from the water pump, fan or alternator but you never know.

I would sooner than later Loosen the belt at least and check the Water pump Pulley + alternator pulley like suggested for smoothness.
It could start making the racket and be self destructing faster than you can stop to check it out.
Its for sure rotational with the engine.
Also mentioned fan touching shroud or rad or such= Same worth checking,

Looking at the video specifically the rotating fan the engine load/idle changes when the noise starts so something is rubbing or grinding.
As Alex suggests take a look at the inside of the rocker cover its only two bolts and 5 minutes.
Also did you try running it with the belt removed yet?

High lift rockers ?
Not all rockers clear the Minifin rockerbox, with 1.4:1 and above you need to relieve the inside by quite a lot.

I drove the car all weekend and it only happened a few times, but stopped before I could pull over safely and check. Seems to be happening less and for shorter periods of time.
I am going to have to see if the tips of my fan blades look damaged. Maybe the bottle caused some damage...but strange that it comes and goes.

Any chance this might be related to the water bottle episode you mentioned in another current thread?

Drove it another 30 last night and then back to work today and it hasn't made the noise again. Never a fan of mystery sounds that just pop up and then go away...

I do have the factory aux fan and it comes on and off on its own, controlled by a sensor and relay. When I filmed that, I had just parked up after a 20 min drive to work so the fan would probably be kicking on and off.

I, too, looked at the belt and wondered if it was fluttering, but then decided the white marks on it just fooled me (?)
also , do you have an electrically activated secondary cooling fan? Normally would only run when hot.

Right on. Im going to have to get it to make the noise again. My drive to work is 20 mins of backroad fun. Didnt hear it until I was within a mile of the office so I'll see if the same is true about the way home.
I just looked any I bought the pump in July of 2017 and it is covered for 3 years so if I had to hope for either to be the problem, I really hope its that one

Remove the belt and run it for a short period to see if it changes anything.

I was thinking the same as I noticed that. The water pump was replaced with one from Mini Spares. Their upgraded one with composite impeller and rounded seal surface. I seriously hope its not that BUT i'll give that and the alt a better look.
I went out before and started it again and the noise is not there. Makes me think heat is involved...hot bearing perhaps.

Near the end of the video clip the noise picks up and becomes more constant. When that happens it looks like the fan belt begins to flutter quite a bit. That makes me suspect either a water pump or alternator bearing.
Try using a long screwdriver as a stethoscope. Put the screwdriver's tip against various points on the engine, water pump, and alternator then rest your ear against the handle.

On my way into the office, this new sound just cropped up. Does NOT sound fun:-( As I’m at the office, I can’t really dive into it but you better believe I will tonight. Anyone have any clue what this could be? I opened the valve cover and the noise didn’t change so it’s not from there. I rebuilt the motor a few years ago and its been solid since. Oil pressure is where it usually is and water temp was spot on. Just when you think all is well in your mini world...
