Strange Noise While At Idle

[PLEEZN]

There is a rattling sound coming from the rear of the engine when its idling. It sounds like a dry bearing of some kind. i thought it was a idler bearing at first but ruled that after some further investigation, found that it was coming from the rear of the engine bay, so then i thought it might be a turbo bearing but its coming from the opposite side of the engine, so i have only one idea left and that is its the thrust bearing from the clutch, but not entirely sure. anyone got any ideas or know for sure what it is? any help much appreciated.

I like your last idea.

There is a thread in the "drivetrain" section covering similar noises. If you can push your clutch in, and the noise stops, then I think that was indicative of it being your spigot or thrust bearing in the gearbox?
