my 97 z34 whines occasiounally when driving, it is coming frome either the engine or transmission. it has made a slight whine ever since i have owned it but only around 3-4 grand but recently it makes a real loud whine and all rpms. it only does it once it after about 10 mins of driving. if anyone knows what it could be please let me know.

Dose it do it when you turn or just drive. poss. a littel better exp. will help
