So my crankshaft timing sprocket keyway blew out and I was able to find a used one only to discover that the key part on the crankshaft is half gone. I can't tell for sure if the key is replaceable. There is a visible gap at the front of the key leading me to believe it may be removable. Any help would be appreciated.

 

Year, motor? If you're talking about the key that fits into the slot on the crankshaft they are easy to find and easy to replace.

 

Its a 90 3.0 v6. Was just able to punch it out. Found some info on another thread. Guess its a woodruff key. Thanks for the reply.
