It's definitely the injectors rattling if it stops dead at 3k...
When they get older they tend to rattle on preinjection... Get a screwdriver and put it on the injectors and place the handle in your ear, you'll hear the rattle you're on about through the screwdriver. If you're that bothered by it, you can replace the injectors for those from a doner vehicle, but it doesn't cause any damage them rattling...
The crank pulley is fairly obvious, it wobbles if it's failing and it won't be the turbo bearings, that's a police siren noise or a whining whistly noise, followed by blue smoke, LOTS of oil in the inlet... I've not heard of a HDi popping a turbo for a long time though, they don't really tend to fail as standard until very high miles, or through lack of servicing.
