Yours looked pretty good, I'm kinda curious if there's anything that Fluidampr might have as an upgrade, if Damper Doctor is just remaking the factory unit the same way. (I have no idea, I'm curious your thoughts too - can you post pics please?)

Then again... A balancer might not need an upgrade if the factory unit is good enough of a design... But this is an area where I just haven't spent a lot of time thinking about it. They kinda just work or they don't.

The nice thing about the factory dampener is that the dampening ring is contained inside the pulley.
So when the rubber holding the ring to the pulley degrades, the ring bounces around the inside of the pulley, making noise.
The TCI "rattler" crank dampener works similarly in that it makes noise when the dampener goes bad.
This is the principle for SFI approved parts for racing.
So that when a part fails at high rpm, pieces aren't sent flying everywhere. (most of the time)

On many factory engines the dampener ring is on the outside of the crank hub.
When the rubber fails the ring can fall off.

Hadn't thought about it that way - that's actually a really good idea, and could show yet another way that this engine is designed a lot better than what Chrysler would have specified. The sleeves around the pistons are a big feature of this kind of rebuildable design, just like much heavier-duty engines. Sad that the valves ended up being such a weak point.

I Just want to say thanks for all of this great information! I was finally able to locate the super annoying noise coming from the harmonic balancer! Will be sending out to refinished ASAP!
