Turbo squeak/rattle

[jayson86]

I've got an 08 6.4 w/ 74000 miles. It's dpf delete, 4" straight pipe, h&s mini max. The day after I bought the truck it developed a bad squeal which was tracked to the tensioner. Replaced that and it helped but still a squeak. It seems to be coming from the turbo closest to the drivers side. The one with the box attached to it. I Also noticed oil under that turbo. I still get boost but not as much as I did, and tons of black smoke even without tune. I have a video if anyone knows how to post it

read johncasey37 's post about r&r turbo without removing cab. Then go look in your turbo intake and see if the fins are chewed up. From the sounds of it, it just might be the same problem. Hopefully not, but it sounds like it. Good luck....
