Thread: Whine at cold idle

hey guys, how are you going?

i've been trolling the forums for a few months so far, lots of good info to be had.

i've just done a search, and for the love of me, i couldnt find my situation with the search terms that i was using. so here goes:

car: 1995 build disco 2 3.9L V8 auto
mileage: ~230,500km's
mods: none, all OEM parts replaced
upkeep: just had a 230,000km service

issue: no driveability issues, vehicle starts fine, accelerates as-per-usual , etc etc, but there has been an unusual whine/ vacuum cleaner sound develop. tonight, for the very first time since i've driven the car [had it in the family since new], there was a high pitched, but rather subtle whistle/ whine/ vacuum cleaner sound, that made itself apparent upon cold start up, disappeared when loaded, but then repeated itself during idle/ deceleration when in "D".

my old man reckons it's not mechanical, and from what i've read here the closest thing that it could be might be the transfer cover, but im not sure if im even in the right ball park with this one. the sound seems to be coming from under the passenger cabin.

sorry if my post was vague, but thanks for taking the time to read over it, and any help would be appreciated- just want to keep the old girl going as smoothly as possible, forever

cheers,

it'd be interesting to see if it is either the exhaust mani/ intake mani, get it fixed and keep her going smooth

thanks again guys- i'll update this thread when i've zeroed in on the noise.

cheers!

Check the Power Steering pump reservoir and make sure it has oil, with the engine idling get someone to turn the steering wheel and listen for noise, also check tensioner pulleys by removing belt and see if the noise stops, Regards Frank.
