turbine sound while driving
Got a 1983 300 CD turbo with 400,000 miles. Car is still in mint condition inside and out and drives smoothly and doesn't idle rough.
The last few days the car began to make a sound that sounds like a turbine engine coming up to speed when I accelerate and decreases when I slow down.
The car runs great, no change in performance or handling. When standing still the sound is gone and the car hums beautifully.
Any idea what that turbine like sound could be and what to do about it?
Thanks, appreciate the input
