1999 ''ringing''
Hi all, I have a 1999 f350 7.3l with 82600 orig. miles on it and it sounds like there is a ''ringing'' inside my engine. Infact I had a friend yesterday say that it sounded like a squealing pulley. I have another friend that has a 2000 f250 with a 7.3l in it and he says that all the 1999's had this ''ringing'' and that it is normal. Is this true have any of you guys herd of this or is it a problem? I remember reading that the injectors are different in a 1999, is this the reason? What do you guys think?

Thanks for the speedy reply guys, I've had my tranny checked about 4 different times and the fluid is clean as could be, and I dont tow with it, so im sure its not that. I replaced the belt myself last summer with a genuine ford belt from dealer. I guess i should've spun the pulleys to see if any one of them squeaked but would'nt a bad pulley be pretty evident?

if its a high pitch ringing, it could be the impeller on your turbo. Shove your camera in there and take a photo and examine it. Or maybe your turbo bearing is going and the impeller is touching the sidewall ever so slightly under load. That is very possible.

I've had that high pitched ringing for a while, but I may have found the cause. I'll be replacing the turbo as soon as I get a new one.
