Folks, I've got one of them there 08 6.4 f350s with a high pitched squeal at high load, and 30 psi boost. Rusty had one a while back with somewhat the same symptoms. I believe its cab pullin' time!
There is three expansion joints back there, one on each up pipe, and one after the diesel oxidation catalyst. I'm betting its heating up and blowing out of one of them.I remember hearing of similar problems on the 6.0... IIRC cracked y-pipes were an issue. Are you thinking a similar problem exists in the 6.4 or do you think it's something more serious?
Nope, the noise I heard, ain't natural!or could he actualy be hearing the turbos?
