1998 Buick LeSabre with about 60,000 miles on it … for the last 6 weeks there has been a constant whirring sound that is loudest right after ignition. When hitting the accelerator, it volume goes up, too. Initially thought it might be a belt but it’s not. My mechanic suggests it could be the alternator.
Thoughts on this? Advice? I figure that the low mileage (I bought three years ago at 35,000 miles) makes it worthwhile to pay for the fix. Also not sure how long it’s OK to keep running it with that noise.
Had the intake gasket replaced in February.
