Strange engine noise (Turbo screech?)

[Garf]

Linking to a video of what I'm talking about, You'll notice the noise after I shut off the engine. Sounds like slight metal on metal contact to me but I'm not 100% sure if its the turbo or what it would be. Anyone have any ideas? Am I just being paranoid or is my turbo unhealthy?





UPDATE:

IT WAS THE FAN!!! Thank you so much guys! I'm going to keep this thread up for anyone in the future that runs into this and comes here for answers.

That gives me some comfort. I still would love some more input from others but glad it's not something totally alien. I've had boosted cars before so metal on metalish noises are a natural fear.

Sounds normal to me. My 6.0 turbo spins for 15-20sec after the truck is shut off. Sounds a lot like that.

Seems like it's your fan. If you look at the right side of the screen it looks to be like the fan slows and stops with the sound. As the fan slows down the squeaking subsides then it stops.

It's hard to say for sure with vid but i have to agree it sounds like the fan.

If anyone is ever worried about turbo issues there are some things to you can check and good chance will show issues (bearing wear ones).
If you remove intake to turbo so you can touch intake side, with little effort move the impeller sid to side and slowly spin it.
1)does it ever touch the sides, are there any rub marks on housing etc.
2) can you move shaft back and forth (front to back).

If any of those are yes you need to look at whats wrong, could be thrust bearing, shaft center bearing etc.
When engine is running the oil pressure will also cushion and float the shaft to.

PS: Of course do this with engine off
