Ok i have been noticing a noise lately i think it is somethin with the turbo, it is a noise in addition to the turbo whistle, it is kind of a whine and gets louder with the more rpms and it is not noticable all the time, is this normal or what is it?

 

When do you notice it? At first startup when cold? all the time? or any specific time or condition?

Play in the turbo shaft?

 

Depending on load, turbo whine will get louder. Perfectly normal.

 

i never notice a patern as to when i hear it, sometimes when cold and sometimes when warm, but it is not noticeable all the time.

 

Your plumb safe. Just the turbo singing a happy tune. If you got a trailer, hitch her up and find a fairly steep hill. If it doesn't make kind of a metal on metal noise, your ok.

 

Make sure your turbo pedalstal gasket isn't leaking. Mine starting leaking and I was getting some weird noises from near the turbo. Found the leak by seeing the soot build up under the pedalstal...

 

Ok where do i look at, i guess i don't know where that gasket is?

 

Man,

Of course i'm going to be away on business with no way to get you a pic. If you look where the turbo is, right underneath it is, well, a pedalstal. Probably not the right term, but essentially it holds the turbo in place. Between that pedalstal and the turbo is a gasket. Mine was leaking, which was causing some weird turbo noises... hope it helps

 

Hoffdog, I believe I have the same noise, mine does it more when cold as the turbos starts to spool up it has a whistle to and then a differnt whiring type noise starts in addition to the sound of the turbo as the rpm increase more it goes away and after warmup it is not as noticable.. I have checked every thing but can't find anything wrong. I've wondered if it's the waste gate bypassing?

 

rv that sounds exactly what the way mine sounds
I guess if i get underneath the truck i can see the pedastal, i think i will wait until the ice melts here before i do that.
