I had a broken keyway on a crank for a Subaru, way before I was ever comfortable taking an engine apart.
I did a thing you should NEVER do.
I purchased a new pulley and a new crank bolt. I then added JB Weld to the surface of the crank snout. I then pressed the pulley in, added JB Weld to the keyway (filling it), and then tightened the bolt to the recommended torque setting. I then let the JB Weld cure for a whole weekend.
This lasted for a whole year, when I did an overhaul. I planned the overhaul as soon as I "fixed" the pulley. Never gave me a problem.
Of course, don't do this.
Edit: Let's be clear. No one here is liable for your actions. No matter what, anything you do with your car involves risks. Somethings sometimes works. Somethings NEVER work. You have to be the adult and choose what is best for you.
