Can you drive with a bad crankshaft pulley?

Indeed, if it’s the crank pulley and the harmonic balancer comes off with it and the engine continues to run that can damage the crankshaft. Other pulleys could get distorted if a fastener is missing and in such condition could damage the drive belt riding on the pulley.
