Hey guys, is this Miata worth checking out?

http://stlouis.craigslist.org/cto/1441810589.html

I did some reading on the miata.net buyers guide and a back window fix is said to cost around $400, is that about right? I know kbb values don't much apply to miatas, so how is this price?

Edit: I'm gonna email the owner, but are there any immediate red flags that I don't see?

Sounds like it's got some rough history the owner's pretty raw over...:confused:

Hm, you have a point. I was hoping it was just jokes, but you can never be too safe.

Maybe a better question would be, is a miata a good idea if I want a decently reliable car under 4 grand? Was just hoping to have some fun driving along with it(and there's something about roadsters).

I'm going to look at this car tomorrow, anything particular I need to look at on 1990s? Going to ask when the timing belt was changed because it will be due at 120k assuming it was changed when it was suppose to be, otherwise could I use it as a bargaining chip or should I run from a miata that didn't have a timing belt done on time? Does the price seem high for this car?

I'm bringing the used miata buyer's guide checklist from miata.net with me to run down.

If what hes saying is that closed loop can occur BELOW 4,00rpm due to load and throttle position then he is correct. As far as above 4,000rpm I believe it's always closed loop.

And NCs use wideband sensors for O2 readings. I don't think wideband systems use closed/open loop scenarios.


This should help a bit: http://www.miata.net/garage/hardtop/

There are basically two types of OEM hard top. One has extra insulation and defrost and the other earlier ones do not. That one appears to have a tint on the window.


Miatas are non-interference. So if it snaps your only going to need a timing belt job if that happens. But in all likelyhood if that happens your stranded and will need a tow. Miatas routinely go over the recommended service interval for the belts.

The top doesn't look original. Make sure the fitting is tight.

How serious is the crank shaft issue in 1990s? Google says less than 1% of all cars were affected. Anyone here had experience with this?

Went and drove the car today. 1990, 105k miles was owned by a 60 year old lawyer(allegedly) no records, clean carfax. I'm told it's been garaged all its life(it is being garaged now) and it looks that way to me. The paint is very good, a couple of places(where it's not really noticeable) it's starting to chip away but other than that it's good.

So going down the list, here's what I made note of:

Front/rear underneath:
There is surface rust on the springs, the right rear has been replaced at some point looks newish. I read that I should expect more than usual cabin noise in a miata, but when I started it up you could really hear the exhaust and i'm not sure if it's a good noise or just how loud the car is suppose to be. Gut says it sounds like there's a hole somewhere in the exhaust. Also, when I idled for a few minutes top up, windows down I could smell a little exhaust. I'm not sure if it's coming from outside or not.

Tires/wheels/brakes:

Tires look great, even wear, plenty of tread left. Break pads have just been replaced there's lots of pad left. Rotors look good. There's a bit of a scuff on one of the tires on the rim(scuffed on a curb maybe).

Trunk:
First thing, the battery is not the Panasonic original. It's a duralast(i assume lead acid battery). If I do buy this car, should I replace it with a panasonic one? I didn't see any leaks or rust in the trunk.

Interior:
Things look nice. The guy is replaced the center console plastic because it was cracked at the bottom(OEM part). No apparent stains, scratches or hard wear.

(soft)Top:
Guy says it's original. There's a repaired tear(?) on the right side of the top on the seam where the support bar is(about 8 inches long). Other than that it looks good. How do I tell if it's a mazda part just to double check? On the inside it looks like there's some discoloration.

Under the bonnet:
Looks clean, oil just changed, brake fluid looks good. No cracks in the drive belt or hoses. No corrosion damage on anything.

I tested the clutch on my test drive, still feels ok even though the guy said the clutch hasn't been changed(that he knows of). He wants $3950 for the car, but he wasn't expecting to sell it till next spring, asked me what I'd pay for it and I told him i'll think about it and get back to him. Also planning on calling a dealership to see how much it would cost to have an inspection done.

Edit: any miata savvy stl goons here? I'll buy lunch for taking a look at the car.

This price seems a little high for this car. I was emailing with the guy and he said the car started mis firing, he is going to change spark plugs and wires to see if it fixes the issue. He asked me to post pone the test drive till he can do that. How much is fair price to offer assuming i like it? I think around 4k?

What's a reasonable offer to make for 94 miata(107k miles) no maintenance records except for a replaced radiator? I drove the car, the clutch seemed fine, top is a year old and it's been garaged all it's life. The only thing i found wrong with it is a cracked windshield that's not spreading and it doesn't obstruct vision. Guy wants 3900 for it, I was thinking more like 3200. This is in the midwest.

Picked up a '94 today and loving it. There's a squeaky belt noise when I turn the AC on, but just at the moment when I push the button then goes away. The guy I bought it from only drove it in nice weather and didn't use AC i'm guessing, could not using AC to me using it cause that?

Aside from that it was pouring down rain on my way back home and having never driven rwd car experienced lift off oversteer for the first time :D

94 from a few posts up, it's so tiny compared to everything else I can't wait to park it to my step dad's avalanche. What do auto shops usually charge to do the timing belt/water pump/seals all at once? I'm debating if it's worth paying someone else to do it or just going to our friend's lift in his garage and taking a weekend to do it ourselves.

Edit: AC squeak went away.

It's not hard work at all, and the lift will be convenient a few times but the vast majority of the work is done from up top anyway.

I've seen quotes on the order of ~$1k for the whole job; you can do it yourself for about a fifth of that. It is a lot of work (I took two days to do mine) but it really is all easy work to do, nothing absurdly tedious or anything like that.

I was just reading up on miatanet about the whole ordeal and I guess the lining up of the timing belt sounded something that's really easy to gently caress up and it spooked me a bit. My friend with a lift is into cars(uhh he has a lift in his garage) but I don't know if he's worked on miatas before, but I think with his help we'll get it done. Where is the cheapest place to source all the OEM parts?

I also had a question about changing oil; I've seen some guys on miatanet use full synthetic in their cars and go for 10k intervals which seemed a little long, i would probably feel better with a 5k interval on synthetic since it's suppose to last longer and all that. Should I use synthetic oil and if so, is there a preferred brand?

I have an odd noise when driving my miata(it's a '94). It sounds kind of like rocks bouncing around a tin can; it happens only in the higher RPM range(like above 5k) several seconds after I let off the accelerator. It also seems to be worse when the engine is cold. I can't quite pin point where the noise is coming from though, doesn't seem to be coming from any particular direction just kind of there. Any ideas what it could be?

^^^^^^^^^^^gently caress you and your nice weather! Just kidding, it's been pretty awesome in the STL area lately weather wise, had the top down couple days ago.

Replaced the CAS oil seal today. I bumped the little tooth thing when taking it out of its housing so I didn't really get the chance to mark it off. Tried to estimate where it is.. took like 4 hours all together of loving with it, getting frustrated, chilling out, going back to it.:argh: Good thing I probably won't have to do it again. Then again this was bad planning because I need to replace the valve cover gasket(since it's leaking oil) and could've much more easily done the CAS o ring thing then. Oh well.

I wanted to to my own plugs and wires since I'm getting into wrenching. But when I try to pull them out just the rubber part that slides on the wire pulls out and I just can't take the wire of the top of the plug. What gives? Am i just not pulling hard enough?

Having a weird issue with my tach. At highway speeds it will stick sometimes for a few seconds. I'll be cruising at 75ish, take my foot off the gas, speed will drop 5-7 mph but the tach stays at the same rpm for a couple of seconds then quickly jump down to where it's suppose to be. Is it the instrument cluster?

Can you guys help me diagnose a clutch issue? Recently I noticed whenever I'm doing my usual three pedal dance, the car is jerking a bit/i'm having to give it a little more gas than normal to take off in first. This is the clutch slipping right? When I do the 45 mile an hour clutch test, the rpm needle moves back pretty quick. The car has 113k miles on it and I'm not sure if the clutch has been changed ever. Or could it be the clutch slave cylinder leaking? I haven't taken the wheel off yet to check, it's been so loving cold.

Edit: typos

Ooops i typoed and didn't really explain it well. I meant this from the miata.net garage section:

At 45 MPH in 5th gear, disengage clutch. Rev engine 2k above what it was doing
and pop the clutch. If engine immediately drops back to original RPM area, the
clutch is OK.

I'm gonna do the plugs/wires/filter next week.

Wait, so if at 25mph in 5th it stalls then the clutch is gone?

My fuel economy lately has dropped by 2-3mpg as well, but I chalked it up to winter mix gasoline.

What do I do now? I have a new set of wires that I was going to do today anyway. It appears the PO didn't grease the boots before putting them in. Should I just reach in there with needle nose pliers and try to yank it out the stuck boot?

Russian Bear
Dec 26, 2007


That happened to me too. I would pull the boots out with needle nose pliers and the lead was still attached to the plug. So I just yanked the lead off after that. All went well after I got through the first one. The process was just hosed up - pull the top of the boot off/break the wire(which actually became beneficial because the wire gets in the way when you're trying to get a grip with pliers) then try to get a grip on the crumbling part of the bottom boot as it is disintegrating, then pull out bits of hard rubber from inside the case then spark plugs out, new one in, new wire on. Rinse. Repeat. Ugh.

The weather finally warmed up and I put the top down in what seemed like forever. Driving with it down I noticed the valve tick being kinda loud. Either this just showed up or I wasn't paying attention before, but it seems kind of loud (increases with rpm etc). Last fillup I put half a can of seafoam in the tank, drove it like a motherfucker - got a few more mpgs than before. The weird thing about the valve tick is it gets really loud when the fuel is low, but when I fill the tank it mostly goes away. What's going on here?

I've been changing oil every 4-5k with full synthetic since I do primarily highway driving. When I changed oil in the fall I went to a 10w40 for the winter. Going to switch to 5w40 this oil change coming up; will a lighter weight oil make the ticking worse?

Maybe I got some bad information last year then. The car started every time this winter even when it was like 0 degrees. So what's the recommended oil weight for spring/summer use? (St. Louis area if climate matters)

Russian Bear
Dec 26, 2007


Phone posted:

Replacing the HLAs isn't exactly hard, but it's not easy either. Depending on the severity of the tick, you can do an oil change and see if that gets rid of it. Usually it'll start ticking when you don't have enough oil and switching to a higher weight usually kills it completely.

I had some bad ticking last weekend, but I hadn't started it in like 3 weeks and as soon as the oil was up to temp, it was silent all day.

Thanks for all the info guys. I'm looking in to the HLA cleaning on mnet. Does oil get less viscous as time goes on and it gets broken down?

Got out of class tonight, went to start the car and it wouldn't go in reverse. poo poo. Turned off the car, could shift through all the gears with the clutch in no problem, with the car on though it barely made it into any gear. I had to push my car back out of the parking spot (NAs are so light it's awesome) and managed to get into first and nurse through the gears. My commute back is all highway so the only problem was the speed bump on my street, almost stalled it. I still can't get reverse, the clutch pedal feels like I'm just pushing against the spring and there's no hydraulic pressure. It was dark when I got home so I'll check the reservoir for fluid tomorrow morning. I'm thinking it's the slave cylinder because there was no slipping or any signs of this earlier in the day and I'm pretty sure it's never been replaced. Car is a 94. Any other ideas?

(I'm praying to many gods that it's not something like a throwout bearing)

Russian Bear
Dec 26, 2007


Car is shifting buttery smooth again after slave replacement/bleeding the system. Turns out I'm a huge dummy and didn't bother to actually check the clutch fluid before all this, I just saw the outline on the reservoir and figured it was fine, joke's on me, the prior fluid gummed on the the side and bottom of the reservoir and only looked like it was there. So I don't know how long there hasn't been fluid in the system, hopefully not long enough to gently caress the master as well. The hardest part of this ordeal for me was getting the vacuum line screw into the new slave because I was following manual directions and installing the bolts in reverse order of taking them off and it wasn't working at all because of how it jams the line sideways.

gently caress directions and lesson learned. :toot:

Edit: Unrelated note, is it common for the miata tick to come back after about 3k miles after changing oil? Using 10w30 synthetic.

It's more a part of the bad HLA design. Switch to thicker oil or try to run some detergent through it. If that fails, I do have a spare set of HLAs in good condition. $60+shipping? (Mazdaspeed's price is something ridiculous, I'll look it up tonight)

Thanks for the offer, but I'll try a heavier oil next time. How much work is it to get to the lifters though? By detergent do you mean something like seafoam or another product?
