Whirring Noise, anyone feeling lucky?

Adam Birnbaum #171 Hello everyone, As I was backing out of my garage this morning, on my way to another glorious day at SIR for a much anticipated DE (track testing rear sway bar steroid treatment) I noticed a faint whirring sound. Did I stop and check it out? Of course not. I needed to run by my office first, so I thought I'd check it there in hopes that my prayers to the shark gods along the way would make the noise go away on the trip out. Well at my office the noise was still there. So, before I leave for home again, (I'm at my office now) I thought I'd post to see if anyone would like to take a guess as to what the problem is. I know there are million things it could be, and without hearing it personally it could be anything, but hey, it's 7am on a Sunday so humor me a little. The noise is a low toned whirring noise, that increases with engine RPM. For the life of me, I cannot pinpoint the source of the sound. It seems to emanate from whatever part of the engine I'm listening to. I am convinced that there is some kind of audio warping field surrounding the engine that was designed by Porsche, which requires a factory stethoscope to discern the source of odd engine noises. No doubt installed to protect shark and foolish but somewhat mechanically inclined owner from doing harm to one another. The sound is reminiscent of a small block Ford with a burnt out water pump bearing, only much more quiet. (I never understood the need for the weep hole in those things) I say Ford because I replaced many in my big brother's armada of Mustangs, but never had to in any of my chevy's (yes, that's a dig) My water pump was replaced about 4K miles ago, so it should still be under warranty if that is the case. So, for my eternal gratitude, and a free can of Spam or chipped beef (your pick), anyone want to take guess? Also, any ideas on how to a make or where to purchase a stethoscope so I can do a better job of pinpointing? Lloyd (Johnston), if you're reading this, hold up on that stroker order, we may be going for the bulk discount :). -Adam Birnbaum '88 S4 A/T
tmm #172 Hi Adam, or should I say good morning, Im not sure about your sound, but my tranny make a whirring noise too ususally only after start up and only if I pull the selector to 2...... Ive sat a light and listened to it thinking what the heck and pushed the selector to 3 and it disapeared?? Could be a pump in the tranny just pumping things up to pressure ??? Seems to go away after things heat up. Good luck at the track.
