I have a 1997 Infiniti I30 with 90,000 miles on it. In recent days it has developed a whining sound in the engine. The sound increases in volume and pitch along with rpm (rev the engine and the sound gets louder with higher pitch). Makes the same sound whether or not the car is in gear. The serpentine belt was replaced 20,000 miles ago. The car runs fine with no loss of power. Does this sound like a timing belt issue?
Before I take the car to the dealer (who always tries to upsell me a litany of things) I thought I'd ask this group if they had any thoughts on the matter.
Thanks.
