I think I had this posted in the wrong forum under the engine 911 so i am re-posting it here.
I have a 2006 PSD 6.0l that blew the turbo. Has 106k miles. I had a large truck diesel mechanic near where it blew up replace the turbo. Everything seemed to be fine but started noticing a chirping sound that would start at 2500 rpm but only with a load like pulling a trailer or going up steep grade. I have looked everywhere online to try to find something similar with no luck. The problem is getting worse and I need to find out what it is. Now the noise has gotten worse and it sputters after each chirp. It is still only between 2500 rpm and 2750 rpm. The more I push it on that rpm range the more it will sputter. If I push it enough that it down shifts, it all goes away and drives fine.
I have checked everything attached to the turbo, installed a 5” turbo back exhaust and have bought a Edge cts2 with EGT sensor to help diagnose with no luck.
Here is a link to it going up a hill without towing anything. It didn’t sputter much that you can hear but it would be much worse if I had a trailer on. I'm going to try to post another link later with the sputtering but it's hard to hear it.
