Sounds to me like your harmonic balancer has split.

The question is, has the whole balancer slid out or just the outer ring.
The balancer is two parts of iron with a rubber isolator band between them.
If the balancer has moved then you need to replace it now.
Not a hard task if you get the correct tools. And don't let someone
tell you to beat the thing on with a hammer or draw it in with the bolt.
That's a great way to mess up the crankshaft and main bearings.
If the balancer is fine and the whole crank is actually able to move 1/2"
then that's a "bad thing" and will require serious engine work.
