04 duramax turbo
I have a 2004 Duramax and the turbo has a high pitched sound on acceleration, especially when cold. Power and fuel economy seem to be the same. Any ideas what is causing the noise.

could just be the turbo spooling up. they make a high pitch whine that increases with throttle. it takes more to compress cold air. this is normal. if the power cuts out, or throttle response is not the same as normal, it's possible it's the bearings. you might also check the hoses at turbo and intake to make sure they aren't worn or cracked or loose.

Thanks for your info, This only started about 1 month ago, I know that turbos do have a whine to them, but this is more excessive than I am used to. I have owned the truck from new. I had checked the hoses, they are all in tack. My thought was bearings, but if that was the case, the turbo should have blown a while ago as faulty bearings dont last long at the revs they are turning in there.
