Plan on adding a timing cover to your list of parts. Looks to be about how far mine had walked when I did it last summer. And the water pump was seeping. So, cheers. 🍻
lol. Good luck.

That doesn’t look good. Was your balancer marked? I’m wondering how this was missed during oil changes etc. that type of movement doesn’t happen over night.

The powerbond made by dayco is the go to part. You will find it in a stock replacement form and an SFI race version. Both are proven very reliable, and the stock replacement version is great if you're not racing your car. Also if you are looking to spend extra cash ATI makes a nice SFI approved balancer as well.

I’m in the middle of putting on an ATI balancer on my 1999 6-speed with 75k. I noticed a little wobble so I knew what was happening. So far so good. Read about everything I could about the process before beginning.

The OP's balancer moved forward, almost taking out the steering rack. The only time you replace the timing cover, is if the balancer moves backward, and starts to grind into the timing cover. You DO, however, replace the crankshaft seal, which is pressed into the timing cover.

I replaced mine with the stock powerbond item. They don't come with weight holes anymore, just zero balanced. You can't transfer weights anymore anyway as your balancer has slipped, so you will never know where there weights should be.
I didn't change the seal and don't have any leakage.

B) given all the work that's required to get at the balancer before you can remove it, and with it removed, the seal is right there, and just a several minute task, why would you NOT replace it??

Strange to see it moving forward like that, all the ones I've seen so far including my own have gone backwards, but I guess once the rubber fails it can move in either direction. Probably a bonus for you though as if it had gone that far the other way I imagine it would have been into the timing cover. I went with an original ac delco unit but only because I'm in the UK and found one at a good price here saving import costs. I did have the timing cover seal replaced and opted for the ARP bolt.

Because it was in good condition and an easy job with the car I have.

Often when the balancer moves forward it was the result of the TTY bolt came loose. This happens more often when some one is tracking their car and runs a course that has a long stretch where you are at the top end of third gear
