Commonly Overlooked Maintenance Items (FM Live)

[@roddydykes7053]

Love the one-take format of these videos. Really demonstrates the wealth of knowledge these guys have

[@FlyinMiataVideo]

Thank you! If you ever have any good ideas for topics you'd like to see, let us know!

Coolant overflow tank, which is part of the pressurized cooling system, is now a maintenance item. Either a new one or an aluminum one.

[@synmoo]

Surprised they left this out of the NC.

[@youcanrunnaked]

The NC uses a pressurized cooling system, with an overflow tank made of plastic that gets brittle over time. All of the original tanks out there have either let go, or are about to. Once they break… catastrophic engine failure. It’s really shocking to me that this was not covered.

[@jagboy69]

@@youcanrunnaked Yup! If it's yellow, change that sucker before it leaves you walking or costs you big bucks! Great opportunity to time change the thermostat and coolant flush in one go. (2007 NC, 51k miles) ((wifes barbie mobile))

[@mxwizzard]

Not a matenace item but can you do a video on aftermarket seats that fit a NA that also recline and fit a bigger driver thanks in advance

[@nolahahnshouse3389]

Yes!

[@WASTEssbu]

This please!

[@grahamnelson5376]

If you’re a bigger driver with the seat back then there isn’t going to be room to recline anyways. If you want aftermarket seats and you don’t want your head to tough the top you’ll need fixed back seats with fixed brackets.

[@ChoPi-Eww]

It's a good question, most seats will impinge on the trans tunnel at the front and the door panel at the shoulder

[@Bbeavis]

Well done FM this was quite detailed, accurate, and certainly a concise list of common but not so well known issues.

[@hilgo_velomobile]

This'll be one of the very few -- maybe only -- video that I ever watch more than once. Two thumbs way up!!

[@GR44N]

NB Often overlooked items that apply to me: 6:45 Main Relay 8:15 Slave Cyl /steel braided clutch hose .

[@MaggotAddict21]

I've replaced my slave cylinder 3 times within 40k. Steel braided cable solved most issues. The basic rubber one breaks down and destroys your entire clutch hydraulic system

[@johncrichton5767]

As an ND owner I didnt know about the value in the oil catch can, thank you!

[@ag4allgood]

Yes , the Verus Engineering AOS is the best one out there. Really well made. It took some time to install but worth it.

[@donlemme898]

Really appreciate the info on the radiator. I bought a very low mileage ‘96 NA (32K miles) last year. Will be budgeting for a radiator ASAP

[@FlyinMiataVideo]

Glad we could help!

Replace the overflow tank also. Preferably with a metal one.

Cool video, good advice. Glad I have a 2009 NC Facelift 2.0 Sport ragtop. It's 12 years old with about 35 000 miles, fine-weather-only and a very refined car. I had an NA and spent a small fortune adding stuff that is standard on the NC. Now fitted with short-throw shift, Panasonic 2-DIN AVIC Naviceiver, LED lighting and much more.

I bought a level 3 Thornton chip, $85, for my 06 MIATA with 6 speed AT. Just plug it in and, WOW!!! Bob

[@Millermacs]

Great video and thanks for the info at 16:06, I recently got a NB made in April 98 and the previous owner had all the maintenance records, and I was really surprised to see a "new engine" recipt, and they wrote on it "No oil pressure", thanks for solving that mystery for me haha.

[@FlyinMiataVideo]

@Millermacs You are welcome - sounds like your Miata was one of the ones that was affected, then!

[@elementaljosh]

If I had to take a shot for every maintenance item mentioned that I’ve already had to do on my NA6 I’d be in the hospital right now with alcohol poisoning 😂 also the main relay is no joke, I nearly missed my calc 2 final on my last day of college because one of those blew out. Maybe I’m a masochist but I find constantly doing small things on my car therapeutic, and hopefully it will last another generation if I keep taking care of it that way 🤞

[@markc4768]

30:16 - clutch life... I've been driving and working on MGs - with the infamous carbon throw out bearing - for 55 years. Early on, I had to replace a clutch on a 63 MGB, and because I was ignorant to the rule of never touching the clutch except taking off from a stop or shifting gears (non-synchro trans...) I had to re-replace the throw out bearing after just a couple thousand miles because I was holding the clutch pedal in while starting and at every stop, and while coasting. And, llike the Miata, they are no fun. After that, I changed my driving habits, and learned the art of clutch-less shifting. Twenty years ago this month, I bought my first Miata - with 65,000 miles, and the owner had just replaced the clutch. It now has 246,000 on the odo - clutch release and engage pedal heights haven't moved more than a couple mm' and it never slips. I drilled a hole in the bell housing and threaded in a borescope - the disc is still in good condition after 181,000 miles. I washed it down with bulk brakekleen in a pressure tank, and it still feels freshly broken in...

[@Rumnhammer]

As a long term NA8 turbo owner I would say based on just replacing them the original coolant hoses for the turbo....mine were 20 years old and hard as a rock FM sells new silicone replacements and they are far better. Also the oil drain hose on turbo will need replacement as well. Again I just upgraded to the FM turbo drain hard line, which is great but still the final attachment section is still rubber and will need periodic replacement.

[@matthewkhan3762]

very informative as I have a standard NA and stage 2 BBR NC. Thanks for sharing your Knowledge.

[@FlyinMiataVideo]

Thanks for watching!

[@markw8139]

Awesome comprehensive list.. Which manual do you recommend for a semi competent home mechanic? I’ve done brake discs, auxiliary belts, coolant flush,diff oil changes etc on NA but now looking for the NB2 VVT? Plan on getting one that’s in good shape it’s not my main hobby! Thanks for the info

[@FlyinMiataVideo]

If you can get a set of the official Mazda service manuals, that would be the most complete info out there. Hanes or some of the others have some good info, but forums and online groups can also be a good source of information. We'd also recommend Keith Tanner's "MX-5 Performance Projects" and "How to Build a High Performance MX-5" books, but we might be a little bit bias there. :)

My heater hose blew out for that exact reason and yes it was while driving back from visiting family out of state for Christmas. The shop that did the work replacing the hose (in the middle of nowhere) then mangled the copper inlet pipe getting to it. I only found out because it started to leak. Replaced with oem hoses and 2 clamps and the use of a swagging tool and now it is solid. But all because that cam o ring. Question: Are the oem motor mounts on a '05 mazdaspeed upgraded from other non turbo Miatas?

excellent informative video. a spare fuel pump for NB1 isnt a bad thing to have on hand either

[@FlyinMiataVideo]

The good news is, those aren't terribly difficult to change!

[@maneki9neko]

Very interesting about crank angle sensors causing small misfires that kill the catalytic converter., I have been replacing catalytic converters frequently to meet California emissions rules. Now that the price of CARB cats approaches $1k, finding the cause of failure is getting more interesting. CAS Sensors are too expensive to replace on speculation. I have an oscilloscope. I need to test mine, and look for a weak or irregular signal.

[@alexmessina3383]

Man apart from being being a totally brilliant review (thanks) I was really hoping you would address that hugely annoying deceleration gearbox buzz in the NAs. No one online has pinpointed a cause or a clear solution. I’ve tried heavier viscosity oil (very slight improvement), Redline MT90 (very slight improvement), various ppf realignments (either worse or same) ... what is the cause; what is the fix?? The definitive analysis would be gold😜 Gearbox rebuild kit?? Extension housing bushing?? Main input or output bearing?? So frustrating. Pple say get another box. All boxes are long in the tooth now and many report changeover box with same issue ... 😬

[@FlyinMiataVideo]

Gearbox noise is usually associated with wear, especially the synchros in earlier transmissions. If the buzz is caused by vibrations, you might need to check and replace your engine and diff mounts.

[@giuseppezavaglia9286]

Correct me if I'm wrong, but 1st gen NC's (and I believe 2nd gens too) often need a thermostat replacement

happened to me on my 08, only with the original thermostat. replaced it and never happened again

[@ryanlubke5842]

Does installing an oil catch can cause issues with the factory warranty ?

[@FlyinMiataVideo]

Not that we're aware of but it's always best to ask your local dealer about it first. If they're happy, you shouldn't have any issue if a warrant claim is brought up in the future.

[@leetNightshade]

Oil catch can "needed" for NC as well? From googling sounds like not necessary since not Direct Injection?

[@williamkozloski6051]

Why do the low mileage nb1 have to worry about thrust bearings compared to higher mileage?

[@FlyinMiataVideo]

Because the ones with thrust bearing problems don't make it to high mileage.

[@MrMeoow91]

Well, my FC RX7 had a mild performance clutch installed from the last owner + car sat for quite a while. Guess what? the slave clutch gave out in less than 2000km. A good additional footnote for anyone buying an older car that had sat for some time.

[@Allen-bm6tz]

What was the transmission issue with the earlier NC? Did it apply to the manual?

[@paulhughes3961]

Do the RX8 hubs install with or without modifications?

[@shihster88]

Do you know if oil catch can fits 2020 Mazda 3 2.0?

[@FlyinMiataVideo]

We've never tested fitment on a Mazda 3.

[@VinceCannavaII]

Does the catch can fit the ND ever need to be removed and deep cleaned since you can't access the sludge at the bottom like the other style of catch cans for the earlier models?

[@FlyinMiataVideo]

We'd recommend taking it apart for cleaning, if needed. It's a fairly easy unit to remove and take apart for cleaning, and shouldn't have to be done very often.

[@Paintppa1]

Things that relate to automatic transmission maintenance?

[@daberin2630]

How about the coolant temperature sensors for the ECU and fan switch on NA Miatas?

[@kennethtrinh]

When will the crossflow radiator come back in stock?

[@RetroQGaming]

I was hoping to find it in this video but no luck. In my imported Japanese MX5 (Eunos Roadster) 1.8L with an automatic transmission, I keep eventually having the "hold" light flash and not turn off with the switch on the gearstick like it should. So it prevents the car from going into overdrive and sometimes leads me to run too high rpm. I've tried various sensor replacement, valve/seal replacement, oil replacements, etc but nothing has ever kept it off for more than a few days. Have you ever encountered this due to lack of maintenance on anything specific?

[@FlyinMiataVideo]

Oh boy! We have a truckload of Miata knowledge, however.........we haven't dealt with many automatic transmissions used in these. Sorry.

What all have you guys gotten into having to do as far as "restoring" the wiring to the main relays? I haven't taken a look at mine, but I assume those probably aren't simple blade connectors if you have to depin and replace the end of the wire?

[@FlyinMiataVideo]

We offer a relay kit from Trackspeed that gets rid of a big part of the load that is killing the main relays. Some Deoxit would be a good idea as well as preventative maintenance.

Clutch feel. Similar to brake lines,the rubber lines can stretch and bulge under use. It's subtle, but there.

Amazing, the oldest NA6 seems to be the most bullet proof.

[@footfeathers]

1. I recently purchased (from FM - I'm local in GJ) all the suspension bushings and motor mounts for my 95'. What a difference! 2. Does anyone have suggestions for the drop in idle RPMs when I come to a stop? Happens whether I'm in neutral, have the clutch in, AC on or not. It drops to like 400 RPMs. The other question is I have a small crack in the rear plastic window. The top is perfect otherwise. Is there any way to replace either the clear plastic window or replace the zip-in rear top panel? I know this video is 7 mos old but I appreciate any responses.

[@FlyinMiataVideo]

You don't say what year your car is, but the NA did have a tendency to idle droop that can be adjusted out with the throttle bypass screw. That plastic window question indicates that you're probably in an NA. For rear window repair, go to an upholstery shop and they should be able to help. This sort of work is done on boats all the time. The stitching might not be OE quality.

Hi, i've got a 1.6 1999 NB and my brakes or something else is squeaking when I turn my wheels when I start in the morning.. even when I'm not on the brakes. I really don't know why this is happening because my discs and pads look good

If you've been looking to buy one for 12 years and haven't been satisfied with anything available, you might need to adjust your expectations. Most people do not perfectly maintain their cars. These cars are generally rock solid reliable and don't usually need an exhaustive list of parts being replaced. You should expect to need to do maintenance on one of these cars though, just like any other car. Just find one that isn't in shitbox condition, buy it, and deal with whatever maintenance your particular car may need yourself. It sounds like the owners you want to buy from are the kind that don't sell their Miata/s.
