Turbo noize

[dippy]

Hi guys

Recently starting getting a metalic whirring noise from the turbo side of my  05 ba and I'm wondering if anyone would have any idea what it could be... sounds like metal rubbing and when the car stops or is turned off it sounds like it spools down much like a turbine. I figured the turbo might be oil starved. Possibly clogged oil feed filter. Already ordered a replacement however I'm a newbie to fords and have never heard this type o noise before.

Any input greatly appreciated. 

Car is mostly stock just has turbo back exhaust.

Cheers

Hi mate, it's normal to hear the turbo wheel still spinning when you turn the car off. There is a difference between hearing it spinning freely, and metal grinding however. Unfortunately you need someone experienced to tell you the difference - nobody on a forum can tell you without hearing it

Take the air intake pipe off the front of the turbo and gently push on the nut on the front wheel (obviously once it's cooled down or with nice thick gloves on) backwards and forwards and side to side and if either the blades touch the housing or it moves backwards/forwards further than a few mm then it's possible the CHRA on the turbo is damaged in some way (by oil starvation is the most common occurrence in these vehicles).

If it sounds like this, then its probably cooked. Like tucker said, you will hear the difference when the bearings have given way. Its a very obvious noise.
