Default ATI damper fell off. Bolt broke or came out. Bets?

So my damper came off today on my way back to the office after lunch. I can't tell if the bolt broke or came out at this point. Once I get it towed home I will put it on the lift and take it apart. Any bets? Never seen or had this problem in my life.

I attached the best picture I could get in the parking lot.

Hopefully for you the bolt fell out because if it broke that would be very difficult to extract.

I agree. I just can't imagine how the bolt would have come out. the torque rating it very high.

Dude that sucks! I think the OEM crank bolt is a one-time use. Did you use an aftermarket bolt when it was installed or the same one that came out?

Here a link to his build. Look like he got a ARP Balancer Bolt.

Wow!

Be very curious to know the details of the install. After having my OEM come out, not in a hurry to have that happen again.

From the pic, I'm voting for broken: When mine came off, the bolt was sticking out the back of the damper and into the crank snout, and fishing it out was a PITA. The longer ARP bolt ought to make it even more so.

Thanks guys. It's headed home now. I used a arp bolt. I'll have it apart this evening. Praying for the best.

A few other questions if you recall.
Red Loctite?
Washer lube?
Torque Setting?

Yeah, it's next to blinker fluid.

The ARP bolt I got came with a packet of some thick *** greasy lubey stuff. My wife said no, so I used it on both sides of the washer. I did NOT put it on the threads, even though the instructions said to, because that seemed just plain stupid.

My guess is the bolt just loosened up over time.

Well. Bolt came out. That's I guess good/bad news being that I don't have to drill out a bolt. Bad news. The crank is ate up. No clue what I should do.

Dang. Sorry man. Not sure what you would do either. I know worst case scenario would be time for a 400+ CI Stroker. Best case, maybe you just try and reinstall the balancer? Either way sorry for your troubles, sucks seeing this.

it's not stupid, but it probably won't fall out

And here I thought I had issues messing up the first crank thread from pulling the stock balancer trying to install that same balancer this weekend. I am definitely not an engine expert but I would try and press the ati balancer back on there as mentioned with a new arp or gm bolt and see if it holds or causes any vibrations. I would think that is worth a shot given the cost of the alternatives. I recommend the hawk ls tool from colorado speed. If the balancer slips back on by hand then you know your answer at that point.
