Engine whine.... part of the usual LS1 language or is something up? Got a 99 WS-6 w/ about 70K on the clock. Ever since i bought the car, the engine seems to have been pretty noisy. I never paid much attention to it because it performed like a champ ('cept for the power steering but i'll get to that). It wasn't until i rode in my friends 00 SS (M6) that i started to worry. His didn't whine really at all and the steering was excellent (again, i'll get to the steering).
My car startup sounds fine. Once i start moving though in 1st gear, as the tach climbs the whine intensifies until i shift. 2nd gear isn't as bad but it still whines. I do have a bit of trouble with steering when the car is going slow. Takes alot more effort than needed to turn the wheel at low speeds (i usually have to use 2 hands, can't do the "palm spin" with mine). At low speeds when i turn the car whines even more. So i thought it could be the power steering... i check it but nothing seems wrong. Not to mention that wouldn't really explain why it whines when i'm driving in a straight line.
Transmission maybe? I would think unlikely because i had it taken in to a local car shop for a tune up (after i did my header install) and they checked all the fluids saying everything was as it should be.... still whines though.
Can't really think of any other way to give a better description of my problem so i'm just gonna ask straight up.... why does it whine?

Mine has a whine as well, but it will do it in neutral. Actually sounds like it's coming from the back of the motor/intake area. I was wondering if I'm hearing a vacuum leak, like maybe the MAP sensor line is leaking or whatever the heck is on the back of the intake. Anyway, I haven't been able to figure mine out.

Duh, I'm an idiot, I dunno why I always thought the car would need the serpintine belt on too run, but I guess as long as it isn't running long, it doesn't need a waterpump or alternator, huh?

My 98 m6 z has whined since I bought it in 99 in low gears, 100k miles later no ill effects, except ac compressor died but still whines today, my rearend has had a leak for ever now but I have never seen any spill on the ground, but never had any problem with power steering either. I always liked seeing the look on mustang owners face when I cruised by in first, they must think i'm s/c because they freeze up like they saw a ghost as I pass by lol. I don't know what is causing it but I would sware it is coming from the motor area??
Oh my T56 has been anything but spectacular, It has needed a rebuild for couple years now and I'm still running factory clutch at 122k WTF?? I wonder if this has to do with the whine?? My t56 began giving problems on cold mornings shifting to 3rd, it would grind know matter what I tried. I'll find out soon since college is done and paid for and my car will be my new hobby. Good luck.
