#1 of 3 2004 Sienna Exhaust Noise by djflurry Apr 27, 2009 (11:31 am)
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?

Replying to: djflurry (Apr 27, 2009 11:31 am) Is this noise RPM related? Does it go away, or get quieter/louder if the gas pedal is pressed? Replies to this message: djflurry (Apr 30, 2009 12:52 pm)

Replying to: samilcar (Apr 30, 2009 10:05 am) 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
