I keep hearing that the timing belt needs to be changed around 60k, but my car has 97k on it and the timing belt has never been changed to my knowledge.* Some people are telling me to ride it till it breaks cuz it won't hurt anything badly and others are saying change it now, but when I priced changing it one mechanic told me he wouldn't touch it because it has a double overhead cam in it which complicated matters and the dealership tells me it will be $500 to change - ouch!* I would like to know if anyone has had them break and how many miles were on it when it happened and how expensive the damage, if any, was... :wacko: Thanks!
If it breaks, your engine won't be damaged - the Miata engine is what's known as a non-interference design. This means that if the timing goes out of whack for any reason (like, say, a broken timing belt), the valves will not hit the pistons or cause anything else in the engine to break.
So that much is true. But...at nearly 100k, you're basically asking for the timing belt to break exactly when you don't want it to. And that's usually when you're out in the middle of nowhere.
Yes, it will be a little pricey. But you can do much, much better than the 500 bones your dealer wants - find a good shop that specializes in imports and get their quote. I'm betting it'll be closer to $200-300. And really, that's cheap peace of mind.
Let us know what you decide. Oh, and welcome to the forums! :)
