Tin can rattle upon cold start and driving m: UPDATE not wastegate

[patire19]

Hey guys when I start my gen 2 all of a sudden I will get a tin can rattle upon starting and driving for usually the first 5 minutes. It sounds like there’s a marble inside of a tin can bouncing around. I’ve checked the heat shields but that hasn’t seemed to fix it. Any ideas?

probably need the wastegate spring mod..

mine was quite bad since i got it at 9K miles but i did this last year or something and its been nice and quiet ever since..

a very tinny rattle noise that suddenly disapears after a min or two of warmup..

2015 - 2020 Ford F150 - 3.5 Wastegate rattle fixed! - To justanengineer ...THANK YOU!!! This really works! Adding a spring from the wastegate linkage to an anchor point on the turbo, the light spring pressure keeps the linkage from chattering. This is the Lowes spring and part number he posted...

I have the same problem on my gen 2 with 37k miles. Just curious, What and where are the heat shields you mention?

absolutly not, have you ever hear cam phase during five minutes, and it' s not at all the same noise...
No doubt it 's the waste gate rattle during warm up as said @downforce137
This sound is well known, you can avoid it with the spring, others say don't put the spring, so it's up to you...

mine as riight in the center of the car and had two or three clamps that i replaced

So It’s definitely not the wastegate. I did the recommended spring fix. Below is the video I took of the sound. It’s definitely in that area that’s creating the tin can sound. Any ideas?

Did you check al the heat shields and associated band clamps under the truck? I had one let go and it took me a little while to track down.

I checked the clamps under the truck, the sound does go away a bit once things warm up. Are the heat shields all in the engine bay?
