Someone diagnose this noise please

I say sound but not sure if I have more than one problem here, basically car sounds rough as fook at the moment.

That's the car fully warmed up. Don't think it's the dephaser as with the bonnet open there's no definitive noise coming from the top end, although it is on 101,000 miles original pulley.

Pure motorsport air con delete kit with new alternator, not sure if it's the PAS pump or water pump?

Sounds like a bearing. Possibly alternator or power steering pump if the noise is that area.
Take the aux belt off and briefly run it to see if noise has gone.

Try turning the steering and see if the noise changes.

Well the alternator is barely a thousand miles old and I'm sure the sound was there before so my bet would be on the pas pump or water pump.

Whats the average lifespan of a dephaser? I've been expecting mine to play up since 80k, perhaps it may have finally happened.

How long is a piece of string regarding a dephaser. Water pumps are not indestructible mine has been changed on mine before I owned it due to it dying.

Mine sounded like that... Thought it was the dephaser but turned out the plastic cambelt tensioner broke into 4 pieces. Hard to tell by the sound on the vid but mine all of a sudden sounded like a tractor.
