If you have a knocking sound while the engine is running, I doubt it's a flywheel, maybe a rod? But why guess at this point? Make sure the oil level is correct and you have pressure. Then do some diagnostic work (mechanic) to determine what exactly is the issue. You might not need a new motor.


if you hear nocking while idle fly wheel cracked
