1990 is old enough the average Mazda dealer *might* have one tech who heard about it once reading a technical magazine. Just watch the crankshaft nose run, if it's wobbling around like crazy don't buy it, or prepare to replace the engine. A video of a wobbly crank, https://www.youtube.com/watch?v=P75feCy_MRM https://www.youtube.com/watch?v=tteqBH4jgo4 The loctite fix could work, but it is just a stop gap. You could replace the whole crankshaft, but it is a lot easier and affordable to get a whole new engine and put it in. If the crankshaft isn't wobbling, really do your research first. The usual cause blamed is the timing belt being replaced and incorrect torque values followed. I have a 90 with 161k miles and the crank is perfect right now. The previous owner had inspected the keyway, found no damage, and still did the loctite fix with an album of pictures for proof. We spent almost 20 minutes just talking about it. He was a little obsessive, but ask the current owner about the SNC. If they don't know or try to play dumb with you, they may be trying to dump off a car with problems. The whole problem probably is overblown anyways.

Interesting thread about the issue here http://forum.miata.net/vb/showthread.php?t=206168 Seems like I should: - check for wobble - ask the owner about short nose crank - probably get a mazda shop to do the loctite fix as a preventative measure.

I don't know if any shops would really touch this. Its basically a stopgap ghetto fix that isn't removable in the event you need to redo anything. You would also only do this if the crank keyway is already worn and the pulley is wobbling. Its not a preventative thing.

I asked about the issue and he knew all about it. His opinion was "dont touch it" and "if it was faulty it would have broken by now." Car was in crazy good shape. No real issues at all aside from a slightly torn edge of a door handle. I put a deposit down to buy it tomorrow.

I have read it comes from over/under torquing the bolt, inserting the key upside down, or not putting the key in far enough. My crank doesn't wobble so I don't worry about, and I don't plan to mess with it until I have too. He just loc tited the crank bolt in place, not any key way repair.

Hi. I think I want a miata. But I don't want to spend too much on one. What is a good miata for about 10K? Is that even a thing? Thanks miata crew!

Finally figured out my misfire. I replaced the crank sensor since that's what I got a code for, but apparently it's just there to tell you "you have a misfire". No poo poo. Checked the coils over good with no signs of burning, and cleaned off the plugs which were a bit sooted from all the misfiring apparently. After driving it around some and getting it warmed up it felt like a fueling issue, so I decided to fill the tank with fresh 93 since it has been sitting almost a year with less than a quarter tank. loving runs almost perfect now, just some hesitation starting out in first gear but then revs up fine. Drove it to work and feels like it's getting better every time I drive it. Must have been a bad batch of gas and/or water in the fuel I suppose.

Depends on where you live, but if it's anywhere in the city or suburbs, no way I'd DD a Miata with a commute like that.

Miatas can be fun to drive but not in the city or around the suburbs, especially if there's a lot of stop and go. The car excels in corners and twisty roads. They're also not the most comfortable car to drive in for long periods of time. Assuming you get stick, it can be pretty annoying in traffic too. If it gets cold where you live, it's also a convertible. How tall are you? It's not exactly great for tall people either. With a commute like that, I would recommend getting a DD like a corolla or civic and then having the Miata for the weekends.

Did you have any Sta-Bil or Seafoam in the tank during storage? TheReverend posted:Oh hey one import component here, Ignore the haters, this is totally doable. I'm about 5'9" and fit comfortably in an NA/NB. My '97 got about 26 mpg and my '05 with a turbo gets ~25 mpg, both averages; during a couple of rare long-distance trips they both got over 30 mpg. You should expect to burn almost 4 gallons each day, then, and since the tank holds ~12 gallons you're looking at filling up twice a week. While your fuel efficiency and driving experience totally depend on the complexity of your commute, it sounds like you're going to be doing mostly highway driving rather than stop & go; this means you should expect decent fuel economy (for a surprisingly inefficient car) as described above. On top of that, your commute will probably be a little boring but not unbearable; take my advice and install a good audio system and you'll be fine. Your level of satisfaction with a Miata will ultimately depend on your weather; if you can put the top down most of the time (bring a hat/visor!) you'll love it.

For what its worth, I deliver pizza in an NB so I'm doing stop and go suburb driving (admittedly, 'burbs in the mountains with lots of twisty roads and limited police presence) for about 5-6 hours and around 100 miles a night. When the weather is  its loving fantastic and I cant believe I get paid to do it. When its cold or raining it gets a little claustrophobic inside and our short winter was significantly less fun than I'd hoped.That said, get in one first and take it for the longest test drive you can get away with. Not just twisty funtime roads. Get stuck in traffic somewhere so you can see if you can put up with the car at its worst.

So I've dailied my miata since I got it, part of that was all highway, part was nothing but stop and go city driving. I found it perfectly suitable in both cases. However I have a PRHT GT NC. For 10k with the need to commute, I would be looking for a GT NC1. PRHT is going to be difficult to find at that price point.

I DD'd my NB to work, and I had about 2-3 hours each way through San Francisco / Silicon Valley traffic. It kept me warm and dry during the occasional rain, but it also had a brand new top, which probably makes a difference. Also, mine's an automatic - which some around here consider heresy - but since it was a "sit in traffic car" for 24+ hours a week it made sense for me. The auto trans actually has a really good feel, all things considered, and you can fake a downshift by pressing the overdrive button if you need to set up a pass.

I DD my '13 NC every day and it's half clear back roads and half bumper to bumper traffic. It's not the most comfortable car in the world but it's perfectly fine for the traffic parts and absolutely fantastic at the clear parts. The manual doesn't bother me in traffic, I don't even think about it. The ride is a lot better than the fiesta st which has become my wife's car after selling her lovely jetta.

I'm a wierdo who thinks manuals are more comfortable in traffic because you're car doesn't accelerate by itself . The nc also has a really light clutch pedal... I think as a DD traffic is much less of a problem than the car being tragically limited by snow and cargo space If you do DD it, take care to watch out for reversing trucks....

If it's the fuel pump, it will get progressively worse over time (except when it runs perfectly for no discernible reason). Sure sounds like it though. Can't offer any more help I'm afraid, had a shop handle it. Working with gas spooks me. Also no garage at that time.

ethanol posted:If you do DD it, take care to watch out for reversing trucks.... Basically treat the road as if you are on a motorcycle, , because people will consistently not see you. If you keep that in mind, the Miata is quick enough to get out of the way or stop quick enough to avoid trouble. TheReverend, if you're driving 55 miles a day, I'd highly recommend an NC. It's gonna have more creature comforts and have a bit more space.
