Am I going to need a new crank and or engine.

Short on cash, and this is the worst possible thing that could have happened right now.

How can I go about fixing it?
Excuse the oil, had a valve cover leak that I just fixed too.. UGH

 

great stuff. New keyway discussion and dozens of real-life 'advice' snippets ranging from idiotic, to idiotic.

Crankshaft keyway repair (Eric Perozziello)

 

"Ideally" you should replace the crankshaft, pulley and key.

Ok, Now that that's out of the way. My freind had this same issue a few years ago. We decided to try JB weld and it worked. It's been ~3 years and all is fine.

 

Its just hard to believe that such a small knick like that in the metal will cause such a huge problem..

the woodruff key wont fit In the same. im guessing its a d series by the timing cover. Those aren't too expensive, I would jb weld that pulley back on and keep on keepin on

 

This was very common on the first Miatas. And the standard fix has been JB weld. There are pages dedicated to this type of repair on miata.net
