LS3 balancer wobble - ok to auto-X?
Hi all - I have a new-to-me 2010 GS auto with about 28K miles on it. The harmonic balancer is (predictably) wobbling, maybe 3-4 mm, and has likely been doing so for some time. It was my father's car and he wouldn't have known it was an issue to look for. I ordered an ATI balancer, ARP bolt, and a crank seal but they won't arrive for a week+.
I have a local auto-X event in a few days and I was hoping to try the 'vette. Do you think it's okay to run it as-is? It's usually a short course (<60 seconds), mostly 1st gear in my T56 F-body, but lots of high RPM work.
Would you run it / risk it or park it?

This is just me...
I can get away with an amazing amount of stupidity, with no ill effects, as long as I'm unaware of any problems.
As soon as I learn of a potential issue, I'm guaranteed an immediate failure.
I'm sure everyone's luck runs differently, but I wouldn't even think of doing it!

Shouldn't drive the car at all with a bad HB. Should it fail completely, it can cause a good bit of damage. Could even wipe out the main bearings pretty quick.
Just wait, replace the HB, then enjoy the car.
