well, this may be a dumb question, but i dont know if this is a normal sound or not... was just under load for the first time with my ’new truck’ 01 24v, towing about 9000# total, going up hill, when I was getting on it and boost was at 20 or so, id let off the pedal and hear a loud windy noise unlike anything ive heard yet (though i havent pulled with a turbo diesel before either). The sound of the turbo ‘relaxing’ was similar to going through a puddle on the right front side of the truck if that makes any sense- it wasn’t water, just that sound, and again, it was unlike any sound id heard without a load, and ive gotten on the pedal before.
Is this normal?

 

sounds like turbo bark happens when you get off the gass real fast maybe?

 

actually, i WAS letting off the gas quickly- that a no-no? i was trying to make it happen- like touching a toothache - haha

 

It's not what you should try to do. A crown and a root canal would cost in the same neighborhood as a new turbo.

 

sounds like the bark to me also. if u ease off it probably wont do it.

 

yeah, reading up on diesel bark, it DOES sound like thats it. i was seeing how towing with the 5.9L compared to my crappy f250 going up my hill (awesome) and now i know... and will engage my right foot govornor.
Thanks again for the info. this is a great resource!
