Whistling noise after cam install??? ideas?
Just thought i'd throw this out there and see if anyone else has heard this same thing.. I just put a TSP V2 cam in my '02 A4 firehawk recently and also a new dbl roller timing chain and pushrods, 921 springs and melling oil pump.. Since installation i now can hear a faint whistling or whine coming from the intake or general area, almost sounds like a blower???? Ive just taken off the intake completely and put new gaskets and new vacuum lines on it and still hear the noise? Could it just be that now the intake is just taking in that much more air because of the cam and it makes that noise?? The timing chain is not making the noise, i very carefully checked it before and after for rubbing and or clearance issues and besides it is most definitely coming from the top of the motor somewhere.. It almost sounds cool but a little annoying at the same time... Any Ideas??? thanks....

Your double roller is grinding away its own clearance into your timing cover, which you didn't clearance enough for the timing chain.
Ask me how I know this. Static clearance check isn't enough. The chain/sprockets will move outwards towards the cover during engine operation.

never pulled intake when doing cam install, but i did pull it afterwards and put new gaskets and fixed some problems behind intake as well as removed the air system, but still have noise? Also checked the IAC motor today seems clean... I dont know what to think, just live with it i guess until i can afford a FAST set up or something....

The GM procedure is a 2-step process in a specific sequence, and manifolds don't crack or otherwise leak when they're tightened this way.

That's all great, but not what I asked..."Did you torque the intake bolts using the GM procedure and torque spec, or just wrench them down by feel?
