Strange noise part 2

I think I have now accurately made a video of the sound that my truck makes. I don't think this is a tea kettle noise, its loud when you shut the truck off then fades once the turbo stops spinning. I am going to buy an edge cs tonight and will be better able to give EOT and ECT temps to determine what the problem is..

Sounds like a slight boost leak to me that causes a whistle as it leaks out under the lower pressure. Double check the boots and all the clamps.

No egr block at all.. At least not that I know of.. Just recently purchased the truck. I feel a bit more confident that its a turbo noise as opposed to coolant pressure. I honestly don't see how that sound could be coolant pressure at all.

Stick your head near the coolant degas bottle and give a listen. Knock on wood that that is not it.

I agree - sounds more like a turbo bearing issue than the tea kettle noise. Can you use a hose like a stethoscope and put it on the turbo as the engine winds down?

Another thread to follow, lol

I hope this turns out well for you. Then I'll know what to look for on my truck. I'll be following closely.
