#1 of 3 2004 Sienna Exhaust Noise by djflurry

my sienna has a noise originating from the exhaust that sounds like a belt squeaking. the dealer has replaced the gasket 3 times. each time, the squeak goes away for several weeks to months, but then comes back. has anyone else had this problem and what is the final fix?

Is this noise RPM related? Does it go away, or get quieter/louder if the gas pedal is pressed?

the noise is heard when the vehicle is idleing and it can be very loud. it sounds like a belt squealing. the dealer has identified it as being associated with a gasket in the exhaust where the manifold connects to the rest of the piping. the gasket has been replaced multiple times but the noise returns within a few weeks or months. i was wondering if anyone had an alternate fix since replacing gaskets isnt working. thanks
