Well back in January I wrecked my car. I thought I was fortunate enough where nothing on the motor was harmed because the frame was close. It cracked the power steering pulley for sure and I thought I dodged a bullet. Well today I noticed my crank pulley as a small crack where a piece is ever so slightly indented it, then there is a hairline crack going around the pulley maybe 2/5th around it. So would this make it unbalanced? Should I replace it? I rather not ruin a motor because of something so simple.

BTW a new one is $146!!!
