That's pretty good. Did it finally fail again? I also found this because early Miatas have the same fecalsample engineering and the same problem: http://www.miata.net/garage/hsue/LoctiteCrank1.html

Here's how NOT to fix the problem: PO had two bolts in here with the crankbolt unevenly on top. Pretty Frankenstein if you ask me and it actually made the problem much worse by having the crankbolt push down on two points only and made the balancer wobble all over the place.

The previous owner thrashed it and I bought it real cheap hoping to fix it. The guy also drilled out the harmonic balancer and installed two bolts in it that went directly into the timing gear and then put the crankshaft bolt on top of that. Can you tell me where to get info on any kit to fix this? I just took it off this afternoon. I think all the rust coloring is metal dust from the keyway that has oxidized over several years. It looks a lot worse in the second picture...the first pic is more accurate. Everything else around the timing gear looks fine, it's just out of the picture and you can't see it.

Here is another picture:

Here is a pic of my "ruined" keyway. What's the best approach to this one? Possibly fixable with Loctite Quickmetal? Please let me know what you think if you've dealt with this... Thanks in advance!
