Ermm have you pulled the intake off the front of the turbo? Sounds like metal on metal

When it makes this noise you can feel it throughout the whole car. It doesnt change when the clutch is depressed and happens if its in gear or not. After a bit of a blip on the throttle the noise goes and the revs stay the same.

My point above would be my first point of call before looking deeper as it will take 5 mins to check the play in the turbo
The IVC my be sticky causing the revs to hold
-
Guest
Yeah I have a couple of hours spare tomorrow but I doubt its play in the turbo as you can feel it in the whole car and its sommin big lol

Was it running ok then all of a sudden started? Does it run smoothly throughout the rev range etc? Boosts all ok?

Before I go out and inspect just thought I'd bump this for anymore suggestions.
I'm trying to stay positive and not think its a bearing thats dying and not the engine needs a rebuild as I'm hoping the fact the engine aint knocking or banging and the running isnt effected when the noise happens.
I'm hoping its a clutch/flywheel/gearbox issuse as when the noise happens you can feel it throughout the whole car and in the gearknob surely if it that a big end or main bearing in the engine and it was that bad to feel it throughout the car and gearbox would dramatically fail streight away and not go away after a short few seconds?!?

It sounds to me like one of the belt-driven ancillaries is seizing.
You can hear one of the drive belts screeching like its struggling to turn something.
Try taking the belts off and starting it again (only for a short period of course) and see if the noise goes.
I'd check; water pump, viscous fan, steering pump, aircon pump and alternator.
Edit; although it sounds hideous, i dont think it sounds engine-internal related.

Right had a good look round it started up fine no noise so switched everything on ac lights heater and the alt belts squealed then the grinding noise happened had a look and can see the crank pully moving slightly back and fourth crank walk??

EDIT: read the past posting before writting.
Alternator belt? When your putting it under load, when having everything turned on

The pully has a good wobble on it

vid on private again.
and in the first vid it sounds like the bearing has gone on the pulley. try spraying a bit off wd40 on the back off the pully and if it goes silent theres the problem

Crank pulley has maybe delammed
Wouldn't keep doing it as its possably grinding up against your oil pump cover.

looks like that botton pulley is going in and out to me ethier way its had it im affraid. i guess next thing is to take the pulley off and lay it on a flat surface to see if its the pulley or the crank .
