So I've been looking at old threads like this one-
Well, a couple thousand miles ago, I noticed a whining noise coming from my engine when it gets revved up a little bit. It seems like the sound has been there since new, but it got louder. It finally prompted me to take it in for timing belt change. I am awaiting diagnosis, but it's likely...
And I'm wondering if it's been confirmed what this noise is? I'm just under 99k miles and it seems early if this is something associated with an idler pulley. Even if it is, I'm wondering if I can stretch replacement until 110k or so when it's time to do the timing belt and everything else? Car is Trifecta tuned so I guess it has had some added stress the past 30k miles or so.
