Hey hey - I just took Larry's initial advice - there's a pretty obvious increase in pull from 5k! All's well that ends well, eh? I'll just be keeping my fingers crossed that the loctite holds...

I'd look carefully at it, FM has found on the high power miatas that the rubber degrades and you lose timing that way also. I've not seen it, but I don't get too many turbo miatas for timing belts, just a few low boost supers.

Probably done < 1500 miles in the 6 months. On the plus side, the wear in the keyway was a good 10 degrees, so I'm just about to load up the high boost map and re-claim the gradual loss of power over the last two years! (assuming all the valve timing was being retarded) Glenn _____ From: Ross Kuhns [mailto:[email protected]] Sent: 08 April 2010 20:37 To: Larry Alster; [email protected]; Miata Powerlist Subject: RE: Crankshaft Loctite Repair Longevity One I did (which had near 100K when I did it) drove all the way across the country and was sold to a friend on the west coast and was still getting the crap run out of it last I heard, had gone a couple years at least like that. Perhaps the mechanic didn't torque it right, or used the newer spec (or even bother to use a torque wrench). Around here the dealers give miata timing belts to the new/inexperienced mechanics because, as I was told by a service guy, it's non-interference and "what can go wrong"... How many miles did it take in 6 months to go from wobble to bad Glenn? Ross _____ From: [email protected] To: [email protected]; [email protected] Subject: RE: Crankshaft Loctite Repair Longevity Date: Thu, 8 Apr 2010 15:15:27 -0400 If it were me I'd drive it like I stole it until it failed and then replace the engine. The question is why if you saw it wobbling 6 months ago did you wait until 2 weeks ago to deal with it after a complete failure? BTW, you're not the only one I've heard of having a crank failure after a dealer did the timing belt. Had a guy in our club have his 95 lose the crank. Of course the dealer denied fault.

Unfortunately after spotting a wobble on the crankshaft accessory pulley 6 months ago, a strange intermittent whirring noise at idle 2 months ago, and finally a loud rattle a idle 2 weeks ago, I found a broken crank key and damage to the key way on my '97 FMII. This has now had the "loctite fix" applied to it including bonding the timing pulley onto the nose of the crank shaft, but what's the list's view of the longevity of the fix? Should I drop the rev limiter and generally baby the car, or is this fix up to normal "bouncing off of the redline at full boost" activity? Annoyingly, the car is only 5k miles (though 2 years) past it's second timing belt change, done by the local dealership when I was feeling flush and lazy.. Any thoughts or experiences? (obviously I've now started saving for the junkyard engine). Thanks, Glenn _____ Hotmail has tools for the New Busy. Search, chat and e-mail from your inbox.
