Mazda MX-5 Miata Maintenance Day

I have tried and once again failed with another attempt to fix the metal to metal clanking sound coming from the rear of the car. It has appeared out of the blue once we swapped my OEM shocks to a set of Bilsteins from a newer Miata. Since then I have greased the rear sway bar bushings. Replaced the rear sway bar end links. Replaced the bushings on the rear sway bar that I had greased before with OEM parts and still the noise persists. So after much research it was suggested that the exhaust hangers may be faulty. They are rubber and after 10 years of use I’m sure they would have lost some of their rigidity.

So I researched the ones to buy. OEM ones on eBay are nearly $20 bux apiece. There are two different kind and a total of five of them in use on our system. One on the pipe under the car, and four holding the exhaust manifold in place. Part # LF46-40-061 of which you use three of, goes under the car and on the back of the muffler closest to the rear of the car (tail pipes). Part # N3H2-40-061A are nearly twice the width of the other hangers and go on the front of the muffler closest to the differential.

But I was not going to spend $100+ bux on OEM hangers, they’re just cheap rubber, I don’t get why they cost so much. Even online part stores like Quirk or Tasca wanted over $10 apiece and something like $13 for the fat ones. No thanks!

The aftermarket hangers from Flyin’ Miata were $8-$9 apiece. The same ones on eBay could be had even cheaper from Kartboy and COBB with various offers for around $40 for a set of 5 with free shipping. But it still seemed excessive for what they really are.

So I started doing more research and found Advance Auto Parts sells Walker Insulators Part # 35119 for just $3 bux and with their generous 20%-30% discounts, it was just $11.55 with tax for the five I bought initially and $5.28 for two more that I bought to double up one of the muffler hangers to replicate the fat design of the OEM.

Everything looked so great, but after a test drive the noise is still there… Fuck me!

Here’s some pix:

A set of five from Advance Auto cost less than one OEM hanger!

The fat OEM hanger on the front of the muffler closest to the diff.

I used a lot of soapy water in a spray bottle to loosen the rubber, for whatever reason the 12mm holes on the OEM hangers were so loose that most of them just popped out with little effort.

new one on the right and old one on the left

the new hangers are 10mm so it took effort to put them on.

but with soapy water sprayed on both rubber and hangers it worked.

and then I had an idea to double up the rubber on the back hanger, it fit just right and introduced more rigidity I believe.

Although the brand name on Advance Auto web site and what I picked up in the store didn’t match, these seem to be good quality product, Made in India.

While inspecting the bottom of the car I noticed my X-brace was bent upwards in a place closest to where the exhaust pipe goes. So I took it off and straightened it out in a vice grip.

Oh how I wished this would have solved my clunky problem… it would have been so awesome especially how cheap the parts were compared to the new OEM end links and even OEM bushings. But fuck it didn’t work… the problem persists and it’s going to drive me crazy until I find the culprit!

Sunday Fun Day Cruising Skyline Drive in Ringwood, New Jersey to High Point State Park and Warwick, New York

Today was a fantastic day to go for a cruise… the weather was perfect! Not too hot, not too sunny… not too much traffic on the roads. So my friend Bill and I headed up Skyline Drive in Ringwood, New Jersey towards Wanaque Reservoir, up Greenwood Lake Tpk to Warwick Tpk to Clinton Road in West Milford, down to Route 23 and then up to the High Point State Park. From there we came back down to Route 94 in Hamburg, New Jersey and headed up to Orange County New York where we turned off on Route 17A and down Route 17 back into New Jersey.

Unlike the many trips to Bear Mountain New York this trip was far more laid back, slower speed and through much more residential areas. Bill and I joked we would do a Foodie Tour visiting the many Ice Cream parlors along the way. But the joke turned into a much tastier reality. Because instead of ice cream parlors we actually visited the source for the ice cream at the various Farms which featured proper Ice Cream Shacks and Barns where the fresh ice cream was Oh Sooo Creamy! We stopped for a root beer float in Orange County New York and then again in Sussex New Jersey for some Frozen Blueberry Yogurt. It was so amazing.

And of course I took a million pix:

Lots of cool cars out on the road today like this fat ass Porsche Cayman… obviously a ton of bikes too!

and some good looking British Midgets…

This ’69 was fully restored by the owner who was proud to point out he’s done a cross country road trip in it all the way to Reno, Nevada wow!

The 2007 Copper Red twins

The ice cream in this place was amazing. I got a blueberry frozen yogurt and it was finger lickin’ good!

Welcome to New York… again

Welcome back to New Jersey!

Mazda MX-5 Miata Maintenance Day

Big day  working on my friend Bill’s Miata today.

We were planning on changing his spark plugs to NGK Laser Iridium plugs as well as put in his new rear end links and replace the license plate light bulbs to the new LED ones I ordered online from Taiwan. The day started early for Bill with a trip to Ramsey Mazda to help diagnose an air conditioning leak… which they spent many hours looking for but couldn’t find.

It was a very wet start to the day. I had to run some errands before meeting Bill at the dealership (to also pick up my rear sway bar bushings) and it was tough to get around with multiple highways flooded. But we managed to meet up, went to have delicious Korean BBQ for lunch and the day suddenly cleared up and became sunny!

So here we go…

I first vacuumed and then blasted the top of the engine with compressed air to clear any debris from the area we were going to work on…

and there was some debris, especially from the underside of the engine cover that left a fine sand-like crap over the wiring

I’ve done the spark plugs on my car at around 50k miles so it was interesting to tackle Bill’s car which has over 100k miles on his and presumably these were his original spark plugs…

Getting to them was easy, instead of unplugging the coil packs I just moved them upwards and out of the way

Most of the holes were clean except for the one next to last, which had a visible amount of oil in it

Shiny new plugs… while undoing the old ones we quickly were faced with them being stubborn and not turning as freely as you’d want them to… so Bill went ahead and sprayed them with PB Blaster… and while they soaked we moved on to doing some other repairs

So we proceeded to changing Bill’s rear end links. I had him using my old take offs as a temporary solution to see if there would be any issue. The shop that did his suspension install used some cheapo aftermarket ones and we quickly discovered that one of the end links had it’s ball ripped out of the housing. So it was nice to see that the OEM pieces held up and we replaced them with new ones.

After this we took another crack at turning the spark plugs and all were loose except for the very first one closest to the front of the car, so we blasted it again and moved on to installing rear sway bar bushings on my car hoping that would stop the clunking… spoiler alert… it didn’t! But now I have new bushings in the back. Oh well!

My old bushings looked fine. We lubed them up with Mobil 1 grease not that long ago. But I was hoping against hope that they were the culprit of my clunking noises. Now I’m not sure what it is. We put on new end links, new bushings…  what could it be? Bad shocks? But bad shocks would surely show wear. I am stumped!

Back to finish the spark plug change:

With enough lube all came out effortlessly. In fact they came out with much less effort that I did on my car doing the dry swap.

The hole that had oil in it was showing clear debris left when the spark plug was removed, so I cleaned it out nicely before installing the new one

All done! Started up no problem. No engine noise. No vibrations. Perfect!

After a short test drive we proceeded to the last job of the day… changing the pesky license plate bulbs on the trunk lid… one of Bill’s burned out and that was the reason I ordered a bunch of them from Taiwan to replace mine as well

I already knew how to approach this change. Pulled out a bunch of fish line and started working my way along the backing of the light unit. The rubber piece that touches the metal trunk lid was very much stuck to it. So the reason for using the fishing line was to break it loose and then the light unit slides to the left and pops out by pulling on the right side of it. And so that’s exactly what I did.

All the plastic tips in tact, nothing snapped or broken. Nothing brittle

Interesting observation the soft top Mazdaspeed spoiler has a little area cut out for the Mazda logo… who would have thunk?

I asked Bill to bring his new ramps so we could change the rear end links, and they fit very nicely into his trunk. Taking up all the space!

The LED’s look perfect!

What a difference a couple of hours make. It was a perfectly sunny day for Bill’s drive home… I had an awesome time working on this car looking forward to another excuse to do something else in the near future. Thanks Bill!

BMW Z4 Roadster Maintenance Day

Today was a Bimmer maintenance kind of day… after taking the car out yesterday to get new rear tires installed I had to talk the owner into doing oil and all the filters change… after all it’s been nearly a year since the last oil change I did on this car.

Interestingly enough the Bridgestone Potenza’s the car had fitted only 20k miles ago were bald. So she went with a newer Bridgestone run-flat that seems to be a much softer tire, drives smoother.

…and it was significantly cheaper price wise than the Potentza’s.

Driving the car to the tire place I noticed the TPMS was illuminated on the dash… turns out someone tried to patch the run flat…

I liked the idea of two jacks lifting the whole car up, I went and ordered a second jack for my garage. Lucky for me Sears had one deeply discounted. I picked up a Craftsman low profile 2 1/2 ton jack for $23 dollars out the door!

Driving the Bimmer I also realized that as similar as this car is to my Miata, it’s significantly different also. Besides the obvious 6 cyliner vs. my 4 cylinder, it has a bigger fuel tank too.

old vs. new tires

When I got home I also went shopping for some Air Filters. I had already ordered the oil and oil filter from Walmart previously, by far the best place to buy oil at only $26 bux a jug for 5QT and $8 bux each additional QT… and another $10 for the oil filter. I went with Castrol EDGE 0W40 Euro Formula like last time.

Walmart didn’t have the air filters. So I shopped around and it’s amazing how arbitrary the pricing is. Both online and in store. Advance Auto had it the cheapest, the Wyckoff store had both the Air Filter and the Cabin Air Filter for $23 total. (*$4 off per filter), I had some gift cards I wanted to use up so I went to the store and the price there was not discounted showing up at $33 total. So I stood at the counter and placed the order on the Internet. It showed up in their system 5 minutes later and I walked out with the same product for $10 bux less than what they sell ins tore. I didn’t get a chance to use my gift cards though… Touche!

I did some more research for the identical filters online and Pep Boys had the air filter two bux cheaper, but cabin filter was nearly double the price… and I’m talking the same exact Purolator stuff.

Anyway…

I love this Bimmer. I got to drive it long before I bought my Miata and in many ways this car inspired me to ditch a big four door sedan and start looking for a little red convertible, my very own roadster.

Much like last year the weather was kind of iffy… but the rain held off

I tackled the Air Filter first… as expected there was a lot of debris…

I don’t believe it was changed in a long time… comparison of old vs. new below:

The Cabin Air Filter was next, and it wasn’t much better. A ton of leaves came falling down out of the cabin filter slot:

So I made sure to vacuum everything in there to make it nice & clean

And the final job was to do the actual oil… first time using my new Craftsman jack, fresh after being picked up in store just minutes ago

Using two jacks makes life so much easier!

It’s amazing that this little car uses almost 7 QT’s of oil… it seemed like it was pouring out there forever:

I left the thing unplugged for a good half hour so all the oil dripped out, but when I went to button it up it was still dripping!

While waiting for the oil to drain I did the filter change on top of the engine which is very convenient!

I don’t know how these mechanics do it… it wasn’t particularly hot day, maybe in the upper 70’s F and I was sweating bullets!

Had to go take a shower when the job was done…

Filling up with oil took no time, and unlike last time when I poured 6QTs in and bought another one of which only half was used, I went ahead and poured in 6.9QT like the forums recommended. The car has no dip stick so I relied on the onboard computer for the read out. The level went up when I went for a drive. And I was more comfortable with it being over half on the read out than on the first mark like in the previous time I did the same oil change. Car felt super smooth after the oil change. I’m really pleased with the way everything worked out.

And it’s time to return the car to it’s owner… What a joy it is to drive!

Wish List: Do a Bondurant Fiat Trackside Experience in an Abarth Fiata Spider

It’s been a few years since I discovered I have no future as a race car driver… that feeling came about behind a wheel of an SRT Charger as I was screeching tires making a turn into one of the high speed corners of Road America in Wisconsin. Since that time though I did three more SRT Track Experiences around the country… but instead of pursuing that sort of “racing” hobby I figured it would be much cheaper to volunteer as a marshal (even though that is expensive as hell in itself). BUT… boy was it fun!

The SRT Track Experiences were run by Richard Petty Racing School. It was one of few subcontractors SRT and other performance brands like AMG relied on to help teach their customers how to drive their cars without actually using their cars… Chrysler for example provided more than a dozen cars, everything from a Crossfire to the Viper… and I as a guest of the Track Experience got to drive every single one of them, multiple times. And at the end of the day I simply walked away… no need to buy new tires, or fix any issues that the car could have developed after being flogged by amateurs around the track. Arrive and drive events in someone else’s vehicles are awesome, certainly better than messing with your own car.

And that’s where the Bondurant Racing School comes in. I remember Bondurant when they ran orange SVT Mustang Cobra’s… I remember that because someone at the company sent me a list of cars for sale when they decided to ditch the blue oval and move on to GM (remember those yellow Corvette’s and black Cadillac’s?) and now they do Chryslers… in particular the Dodge SRT line that I got to experience several times with Richard Petty… luckily FCA, the parent of Dodge also has non-HEMI powered machinery for which Bondurant has a whole separate web site, calling it Fiat Trackside  https://fiattrackside.com/ which seems like a perfect way to experience the Abarth line-up and in particular the Abarth Fiata: Fiat 124 Spiders… and I intend to one day take advantage of their offerings to experience this Italian (Japanese) creation…

If anyone has a hook-up, my birthday is coming up in September feel free to get me some time behind the wheel of the Bondurant Fiata… I’ll take care of the flight to Arizona but the rest I’m too broke to afford.

FIAT brand’s Abarth models, including the all-new 124 Spider Abarth, join the lineup at the legendary Bob Bondurant School of High Performance Driving.

Bondurant Racing School also offers a Teen driving program, which is probably more up my alley than an actual high performance Abarth experience, but I wouldn’t turn either of them down if presented with an opportunity.

I’m not sure how these track experiences operate, and if they carry any similarity to the SRT track experiences which I’ve done several of in Wisconsin, Colorado, California and Florida… I’m sure there are some good folks on the Fiata forums that would spare their VIN# for me to experience these cars on track at the Bondurant facility.

This is definitely high on my wish list!

Mazda Car Wash Day and Detail Clinic

This weekend Chris hosted a car wash & detail clinic day.

I joked that I was preparing for this day by not washing my car for at least two weeks… and several road trips on some rainy days for Motorsport events like the visits to Lime Rock. But in reality every time I do wash my car it seems to rain the next day messing things up. All the pollen in the air, the dust, and it’s a pain in the ass to keep the car clean. I don’t think I’ve ever actually detailed my car, until this weekend!

Chris has a collection of various detailing products that were put to a good use. One of my favorites was the one that turned my headlights that have started to get cloudy to bright and clear again.

Some pix:

This yellow RX-8 was my favorite Mazda at the event… I love the color. I think my next MX-5 will be some shade of yellow!

Yea, please don’t suck Mazda!

Good to see Bill show up with his 2007 GT soft top… I think in the past I’ve assumed it was the first model year NC but I was wrong.

Isn’t that yellow gorgeous?

My turn…

Tackling the headlights…

This is what they looked like before, very cloudy on top…

and this is what they look like after:

as compared to Bill’s car:

and compared to Chris’s car:

and even without washing or detailing Chris’s car looked the best:

To end the day we had the bright idea of attempting to adjust Bill’s new Tokico’s… and then Chris dropped one of the brace nuts into the engine bay… that was the last time we saw it. Even though a lot of time was spent looking for it, it was never found. Luckily the Advance Auto nearby stocked just the right size bright and shiny new ones which I went to pick up to finish the job.

It was a great and very educational day…

Thanks Chris!

Mazda MX-5 Miata Maintenance Day

This father’s day my friend Bill and I decided to fix another issue both of our NC Miata’s were having… my rear stabilizer links were making a clicking sound ever since we installed the Bilstein shocks. His Miata seemed to have aftermarket end links where one of them was ripped out of it’s socket because of possible incorrect install to his massive Flyin’ Miata rear stabilizer bar. So Bill ordered the parts online, came over and as soon as we got the car up on the RhinoRamps it started raining… so we went to the Diner for breakfast. On the way we also stopped by at CarQuest to pick up some more new end link nuts because the old ones on my car were showing signs of wear and I didn’t want them to get stripped. He paid $3.30 apiece at the Mazda dealer… I paid $3.30 for a box of 4 Dorman aftermarket pieces. They looked the same.

Fast forward to some better weather and replacing the end links turned out to be a rather quick job. We did Bill’s car first. Taking them off was easy. But placing new ones on seemed to look weird because they went in on an angle when attached to the stabilizer bar… I was worried if we fastened them in this condition, it was possible that they might fail again.

Luckily we had my car nearby to see exactly what they were meant to look like in correct condition, as installed from factory.

So another idea was to take mine off. Replace them with new ones. And use my old ones as guinea pigs on Bills car to see if they would last. If no failure happens after a few weeks of driving we’ll go ahead and replace them with the new ones. So that’s what we did.

Ironically though, the clicking didn’t stop once we installed new end links on my car. Turns out they were not the problem I was experiencing. Instead it appears that the actual stabilizer bar was bending in such a manner that it was making noise when the chasis of the car twisted on various road conditions, particularly when going onto uneven surfaces, like up a driveway or into parking lots, or hitting pot holes.

I was disappointed that the problem didn’t get fixed, but as we were tinkering under my car I discovered that my differential was covered in fluid and grime. It turns out that the last time I did Castrol Syntrax flush to replace the Mobil 1 75W90, I did something wrong. It’s possible I didn’t tighten the bolts enough. Or that I overfilled the differential. Or that my car didn’t like the Castrol product. I was so concerned about it, I ordered another jug of Mobil 1 since it was proven to work well for a good 20k miles, and did the flush later on in the day. So far after the test drive the car feels smooth. There’s no whine at cruising speeds. And all is well. What I’m concerned about now looking at the old Castrol that I drained from the diff, is a bunch of small aluminum shavings. That doesn’t seem normal to me.

But I guess time will tell if there’s a bigger issue.

Today was a very productive Sunday!

Mazda MX-5 Miata Maintenance Day

Today was a good day!

After the post maintenance test drive my toddler nephew exclaimed: “Oh look it’s Mia and Tia!”

Last week at the Woodcliff Lake Cars & Coffee my buddy Bill with the NC1 Copper Red Soft Top said he needed an oil change, so I volunteered to do it for him. Great! Today was the day to do it, perfect weather… lots of time since it’s the weekend, and besides the oil change we flushed the rear diff too.

Bill’s NC is pushing 104k miles, so it’s got a few more than mine. The area where the trans pairs to the engine was a bit covered with oil, which I guess may be normal for that age. It certainly looks similar as my high mileage Ford Explorer that my mom drives. There was also a lot of grime on the engine cover so I spend much of the time cleaning as the actual oil change took very little time. Actually, it took us the longest to figure out where to jack the car up correctly since his has an Appearance Package with side skirts that stick out beyond the pinch welds that I normally jack my car by.

Here’s some pix:

(first shot with my new Samsung Galaxy J3 6 “budget” smart phone)

Bill’s Miata:

The dreaded Sports Appearance package side skirts… look good from a distance, make the car seem lower to the ground, but a bit tough to work with especially when jacking the car up (and having to remove the jack leaving jack stands in place to lift the other side).

I don’t know if these openings are supposed to look like that or the previous shops/mechanics cut a piece out to get to the jacking point

The wet spot at the joint of transmission and engine

Bill lowered his car 1 inch with Flyin’ Miata Stage 2 kit, so we definitely had to use 2×4’s to get the front high enough for my jack to slide under

All done, first test drive to Advance Auto to recycle old oil and to buy gear lube to flush the rear differential.

Thanks to the great deal at Advance Auto I posted about earlier I got a chance to use both Castrol EDGE and Castrol EDGE Extended Performance + K&N HP-1002 filters on Bill’s oil change and mine…

Back in the air and leveled for the diff flush.

I was hoping that the Castrol Syntrax I used in my car’s last diff flush was going to work out but it seems to me that the quality of Mobil 1 is better so I recommended Bill get Mobil 1 instead.

Discovered one of Bill’s end links had broken off it’s mounting point to the sway bar, so he is going to order some new ones. These are the same pieces that make the clunking sound on my car ever since we replaced my stock shocks with OEM Bilstein’s.

Off on another test drive to get a feel for the rear end of the car… all Good!

Thansk for stopping by Bill!

My car is next, this time I tried the Castrol EDGE Extended Performance to see how it compares to Castrol EDGE I used for the past two oil changes. I’m assuming there will be no difference because I really don’t intend on running the car for 15k miles before the next oil change. In fact I was about 500 miles short of 5k on this one and I have no regrets, I’d rather change it more frequently then less…

This is my 3rd oil change this year, not sure if one more will be necessary before winter time… depends how many races I volunteer.

Mazda MX-5: 1,000+ mile Road Trip from New Jersey to Ontario, Canada for Victoria Day Speedfest

Happy sesquicentennial anniversary Canada!

I had no idea Canada turns 150 until I saw all the colorful banners at the Canadian Tire Motorsports Park. My 500+ mile road trip north was for the same reason I went last year. Victoria Day Speedfest event is an excellent combination of racing series at an amazing facility that makes time fly because you’re having fun.

Unlike last year the weather went completely haywire. On the first day it was warm but super windy. In fact the first order of business upon arrival in Bowmanville was to head to my favorite Poutine place to pick up a big plate of fries with gravy (which I ate in the car, parked at Turn 2 watching cars on track)… driving there I thought there was a sand storm, the wind whipped up all this dust it was hard to see the road in places. Next day it was cold. The following day cold and sunny, so I was freezing and got sunburned. And race day it rained which meant one of the feature PWC series got cancelled. But nevertheless I had a blast!

As usual took lots of pix:

Gas station food… it’s different in Canada!

1st Place Fries at Race Track gas station… yep!

…off to the track we go!

Welcome to Mosport!

Watching the test day activities from Turn 2.

Ironically, throughout the weekend I had the most unexpected favorites. The Micra Cup certainly kicked ass… it almost killed us at Turn 9 on Saturday as two cars lunged at us rolling in the process hitting the tire wall pretty hard while we scattered away. Both drivers walked away but it was a scary incident. Pinty’s Series did an amazing job racing in the wet on Sunday. Who says NASCAR doesn’t do rain tires? They certainly do… while PWC cancelled their Sprint X event because the track started ponding in some areas. But then the rain let up and the final race of the weekend took place… Canadian Touring Car Championship ran, but with half the field chickening out.

I tried to organize a Miata meet-up during the weekend. I failed for the second year in a row. This time I posted on Miata.net but apparently in an inconvenient thread because some dickhead jumped on me for hijacking the thread. And a few more assholes joined in the chorus speculating I must have voted for Trump because I made such a massive mistake posting in a thread where Ontario Canadians responded what cities they live in. To me that was the most appropriate post, but needless to say my efforts were wasted. Nobody wanted to meet. I did see several Miata’s at Mosport. One NA even gave me the flip up headlight “Hello” as I flashed my lights at him driving down towards Mosport Road, but that was that.

I did get a chance to visit my favorite gas station in Canada again… and refuel using the grade of fuel that sponsors the Canadian Porsche GT3 Cup series… Ultra 94. I suspect because of the rain and cold weather I never got better than 33mpg which kind of sucks. I wanted to match 36mpg’s from last year’s trip.

More pix:

Just like in the US, the gas prices differ station to station. So note-to-self for next trip… the Petro-Canada in Cobourg, Ontario has the cheapest price along the 401… also important to remember that just like Sunoco Ultra 93, not all stations carry that grade of fuel. I foolishly visited two gas stations ready to fill up, only to pull away from them because they didn’t sell Ultra 94.

Final fill up in Canada, $40 CAD for half a tank of gas. Oouch!

Similar fill up at Sunoco south of the border… but with a more favorable rate.

Ultra 94 is all over the place at Mosport though, so I’m happy to do my part and support Petro-Canada rather than other Canadian stations like Ultramar, Husky or even Esso in favor of those that support local Motorsport.

I think the highlight of the trip was when my Google Maps GPS welcomed me back to New Jersey! That took me by surprise…

I almost forgot to mention… a few miles before the Canadian border at the Thousand Islands crossing I hit quite the milestone in my Miata 66,666 miles!

That’s the second time this year I’ve rolled over all 6’s, last time being in Wes’s Crown Vic driving it from Pennsylvania to Texas.

Mazda MX-5: Fixing the Door Beltline Molding with NE51-50-640G from Avondale Mazda

UPDATE May 7th: After three days of light/moderate/heavy rain with the new beltline on the passenger door, I’m still having the same issue of water retention. Not a damn thing has changed, except of course I’m out $50 bux…. not thrilled about this! Maybe it’s part of the design to open the door so the water flushes out but it doesn’t sound too reassuring. Certainly wouldn’t want it to start rusting if the car sits around for extended periods of time in all types of weather. Argh!


Ever since I bought my Miata there was a peculiar phenomena happening. After heavy rain or even just washing the car, a bunch of water would pool in the passenger side door that would gush out when the door was opened (otherwise didn’t drain on it’s own).

I shared this video in April of 2015 showing the issue after it rained:

The solution was quite simple, but pricey!

I bought the new beltline molding from Avondale Mazda in Arizona through eBay using one of their $15 off $75 purchase coupons. The part was listed for $65+ and I added another $14 item that I was missing, a battery brace to help secure my DieHard battery (some schmuck that installed the battery for the previous owner didn’t put the brace back on)…. and now the battery is held on only by cables.

Anyway, it wasn’t easy to find instructions on how to remove the old beltline molding. The instructional videos from NA Miata, and the Miata.net how-to for the NB Miata are different. Luckily I had an NC Miata maintenance manual that showed a graphic how to do it. And in the process of attempting to release one of the plastic clips, I promptly broke it. I assume the plastic was brittle and didn’t take much effort to break.

Removal was easy. Re-install was a bit of a pain in the ass because of alignment. But eventually everything fell back in place. And I’m happy that there’s no more gap between the molding and the window. This week it will rain a lot so I’m going to test how the new molding is working out. But I think I’m happy with it!

As usual I took a million pix:

Old molding…

The new and the old molding… clearly the old one at 10 years of age is very much worn and lots of dust around it including some rust on the triangle part of the window to the front of the car.

Lots of cleaning was required.

Voila!
