tooter's manifold adventure...

Setting the record straight:

1. The Yaris stock pulley DOES have a small rubber damping strip.
2. Straight from a Toyota engineer: "The purpose is to reduce noise in the cabin ONLY; it has nothing whatsoever to do with engine longevity".
3. Conclusion: An aftermarket pulley might cause a bit more cabin noise/vibration, but that is all.
4. #3 is proven by the hundreds of aftermarket Yaris pulleys out there with not one provable engine failure or shred of evidence that a solid pulley causes damage on this car.
5. This has all been covered over and over again on this forum and many others -- anyone bothering to do a search first wouldn't need to rehash the argument, at least in reference to the Yaris.

Are we good now?

They didn't do a damn thing else to reduce cabin noise....why'd they pick the crank hub to sound deaden?

probably because it fit, and it came from another car.
