I own a 2004 Grand Prix GT1 with slightly higher kilometers (I think we're up to around 146K) When accelerating with higher RPMs, usually I'll hear a slight whining sound from within the engine but I'm not too concerned as I think I'm just hearing noises that were always there. When the car is idling, it sounds normal, and even if I rev it a little while in park, I hear nothing that seems out of the ordinary. It cruises fine at just under 2000 RPM going 110km ish and has a very smooth ride. Only when I'm accelerating do I hear it, and it only seems to be heard from within the car.
I think I'm just obsessed with having my car run perfectly and am just starting to hear noises that are completely natural.
