turbo noise when cold
This usually happens with the first drive of the day. after, it's gone. Thu turbo makes a noise likebad friction in a bearing but not with a loud pitch. It go's away when I gas it a little more which will than make a turbo release noise. than repeats. I could make a drive, the turbo will make the noise, than ten minutes later I'll drive again and it'll opperate like it should. But the turbo will always apply boost when it should.
Any ideas?

Pull the intake off to get to the turbo.
Reach inside with your hand and see how much play there is on the wheel.
check inside with a flashlight to see if the wheel is contacting the housing.

I think you are describing the EBPV closing on cold mornings.

The EBPV would close even when its warm briefly on start up.
But yes Jim, it probably is that.
The Turbo Wheel can make some strange noises when they contact the housing.
My turbo makes a bit of noise when I first start up in the cold, its not quite lubricated as well as it could be.
If he's not getting enough oil into the journal bearings, then it will rattle around a bit and make strange noises.
When its making the noise on start up, does it make a "wooshing" sound at the tail pipe?

I also discovered that if I let it warm up for 15 min or more, than no issue.

Lots of guys unplug them. If you don't mind letting it warm up good (which you of course should do anyway) sounds like it is working, leave it if you wish.

It is just below and in front of the turbo. A two wire plug connector, the only one there. The computer (PCM) will store a code that it is not working but does not CEL. I've had mine disconnected for the past two years but plugged in back in this winter to see if I could get quicker cab heat due to (global warming) cold. But it warmed up a bit here so the verdict is still out on that. Although I do think it has a purpose to get the cylinders up to temperature quicker in cold climates.
