I am pulling my LT1 engine and wanted to see if anyone could tell me how to check the dual mass flywheel. I bought the car with the engine removal in process but the guy stopped when he scoped the overall job. He told me the engine was knocking and getting worse each time he drove it. I am planning on rebuilding regardless with 130K but wanted to ensure the flywheel is good.

Thanks!

Citing article from Motor Age - June 2005:

How do you diagnose a DMF during clutch replacement? You can first check the friction plate. This is done with the flywheel installed and the clutch removed. Partially install two pressure plate bolts into the flywheel 180 degrees from each other. Use a bar and try to rotate the outer portion of the flywheel in either direction. You should feel approximately 8-11 degrees of movement before the friction ring engages.

You can also make this inspection with a torque turn method. You will need to make an adapter to bolt to the outer half of the DME The specifications are as follows: GM 6.5 L-440 ft-lbs.
