like a said, i just put this new 30 valve in after i resealed it. at idle it makes a unrecognizable sound. using a stethoscope i listen to my accesories, power steering ect. and all sounded fine. Once i give the engine gas it goes away, sounds like its coming from somewhere near the intake manifold on the firewall side. need help plzz

i have the same problem. ive been told that its the ac condenser belt or serpentine belt... do these happen when the ac is on or off. mine only does it when its on and as soon as i turn it off it goes away or when i rev it up. hope this helps
