Strange noise with 850 on cold start

posted by  someone claiming to be Hank on  Sat Dec 28 12:32 CST 2002 [RELATED]


Greetings..

When I first start my 96 850 turbo sedan it spins up to about 1400 rpm when you first crank it.... Anywhere above 1000 rpm when first started the driver can hear a strange moaning sound coming from the engine compartment. If driven cold this sound will get louder as the car is accelerated and fades in and out getting louder and softer in turn independant of speed. However if the car is allowed to come up to operating temp, the only time the sound will be heard is when it is first started and spins to to 1400 on start. At the idle speed of 900 rpm there is no sound and when warm, never any sound.

Thanks in advance!!
