RE: Name that I-5 noise!
I second that diagnosis. I had the same warbling sound before,
didn't we describe it as a turkey sound, was that another thread?
Anyway, I speculated that the shaft on my new replacement water
pump stuck out further than the original one, and was actually
making contact with the inside of the timing belt cover. I spaced
my cover out with some washers, and the noise was minimized if
not banished. I forget if it went completely away.
