Turbo Noise

I hate starting new threads if I don't have to. I did search and found a number of threads already but the descriptions didn't match up for me I don't think.
I did see several had at one time left links to videos but those links have expired.
So anyway, I recorded a 30 second video hoping you guys will give it a listen to and tell me what you think.
In this, I am driving it a bit harder than I normally would, but I'm also getting up to speed on a busy highway.
I am asking more of the turbo than I normally would. It doesn't do this when its low boost.
Also, when rewatchibg the video I thought the car and exhaust sounded awesome. It's not quite as nice in person unfortunately.Yet

Listen Here

I would take off the inlet elbow and give the small nut that holds the compressor wheel in place a good move. If it moves or has any play in it, your bearings may be going. Try also to spin it by hand and feel for any binding or interference at all. Also check your connections for the intercooler to be sure that no air is blowing past them. Let us know.

That sounds daunting, at least the part about getting in as far as the inlet elbow. Will be doing the exhaust soon, would it make sense to check then at the same time?

Inlet elbow comes off with 2 bolts after the turbo inlet hose is removed. Takes under 5 minutes to remove the hose and elbow if you work very slow.

Yes, with the elbow off, you can get your fingers right on the compressor blade nut and give a spin. The exhaust side is actually harder to get to with the down pipe elbow on it. Your better off checking the turbo bearings through the front at the elbow.

I can see the elbow, it looks like it would indeed take 5 minutes to check. As long as you don't count the 15 minutes of me searching my manual for a diagram to see what and where the inlet elbow is exactly
So I do see it.
I had my car in a shop last year, he replaced the wastegate actuator for me, I can see he has used red rtv as a gasket between the elbow and the turbo.
Will that gasket be OK if I remove the elbow or would I need to redo that?

Rob,
I added a pic here so you can see what the elbow looks like, I know you said you found it, but good reference anyways. I would replace the gasket with some parts store bought gasket material rather than RTV. Simply trace out your desired shape using the elbow and cut out. I would not want any RTV near the intake of a turbo. Keep the questions coming if you have them, glad to help.

Alright thanks Kuch I'll ask when I'm over there Monday. Any idea what the material is in case there end up being options?

Just use the standard "paper" type grey gasket material. It is usually sold in a roll at most auto parts stores. Easy to trace and cut with scissors or an xacto blade

Agree 10000% with Kuch on using a real gasket. Imagine if a piece if squished out RTV broke loose and hit the compressor blades spinning at 120,000 RPM!
