Turbo Problem?HELP?

[Im_Your_Hucklberry]

I live down in Texas and it never gets as cold as its been getin and ive noticed that ive been hearing a whooshing or rubbing nosie from my engine and a slight squek when i start it and it only does it for the first 30 to 45 min. the truck is runing and the sound is really noticable when i keep the truck at a constant speed. The sound seems like its coming from the turbo. The truck has 212,000 miles on it and the specs on the truck or in my sig.. So i was wonderin if it was just the cold temp. keeping oil maybe from the turbo. please help any info on the problem is helpful....

does the sound increase/decrease with boost or does it stay constant to motor speed?

I would not imagine it is the turbo. You can pull the intake tube off the turbo and check for scrapping marks on the housing and play in the shaft.

the sound stays the same until i acclerate then it goes away... could it be the bearings in the turbo not getting oil due to the cold weather because i drove it today after it got a little warmer and it didnt make the noise

[MrJohnWayne]

I doubt it. if the turbo was lacking oil you'd know it. It would be a loud screeching, than no more turbo... might be waterpump or fan clutch.

Its the warmup valve doing its thing, it restricts exhaust flow to warm up your engine faste, its perfectly normal dont worry about a thing.

sounds like the exhaust back pressure valve to me, its just doing what its suppose to be doing.
