What are the signs of a cracked flywheel in a 1998 Chevy 350 engine?

Answer:
If you are really talking about an automatic transmission flex-plate, then a clicking noise at a lower rpm that seems to go away as yoiu wrap up the motor would indicate a crack. A maual transmission's flywheel that is cracked will generally cause the cluth to slip, and eat the clutch disc rapidly. There will be a strong smell!
