'03 2.7t 6sp w/ 68K. Noise upon start up.
Please help me diagnose the problem. The noise seemed like a high pitched grinding noise, like a band saw, sounded like metal on metal to me. It was really loud the 1st (Monday) & 2nd (Tuesday) times I started engine cold a week ago. Did not drive it either time. Smoke came out from under the car the second day I started it, I quickly turned it off and I have not seen the smoke again.
The third time I started it (Thursday) the noise was present but was not as loud. The noise seemed to go away after it warmed up and the choke turned off. Same thing on the 4th start up (Friday), I then drove it to my indy mechanic. I did not hear the noise while driving it. The Indy thinks the noise is coming from the left turbo but he is not sure, he said the noise is defineatly from the back left section of the engine as you face it. I did not notice any loss of power when I drove it either. No engine CEL codes or alarms.
Can it be a turbo impellor? Why is the noise present when the engine is cold? Is it a sign of complete failure to come? Any other ideas would be appreciated.
Thanks in advance!

I'll look into that but do you really think its the pump? If this happened to you was it a similar sound? It is a metal on metal grinding sort of noise. It really could of sounded like a impellor hitting the housing. But then I hear that turbos don't even come on until 2000 rpm or so and Icouln't hear it when I was driving.
Thanks!
Thanks!

Same problem and yes is is the secondary air pump that sound like a meat grinder under your hood. I just bought one to replace it cost $424.00, seems like alot for something that you don't really use much.

Hey Let me tell you there is nothing wrong with it. Trust me here. If you replace it you are wasting your money. I don't know where you are located but when it warms it will resolve itself.
