Flexplate issues

How do you know it just cracked tonight?

If it just started making noise tonight and you found it crack how do we know if the crack just spread and got worst enough to hear today?

2 1/2 hours, wow. It might thou but it be a big towing bill if it had to be a two hour tow.

I think I might go for it thou..does it quiet down at certain rpms, if so I try to keep it around there.

My spun rod bearing wasn't knock loud enough to hear til 2,500 rpms. I drove it for around 30-45 mins all together..creeping along at under 35 mph, lol
