project 1990 Mazda Miata [part 19] FIX WATER SLOSHING NOISE!

[@leejk3926]

That's just your MX5 giving you some relaxing wave noises to calm you down.

[@andyvaid69]

Spray inside

[@leejk3926]

@@andyvaid69 Wow you're everywhere, used to seeing you on the facebook page lol

[@jono7183]

I couldn’t figure out the problem until I saw this video. Worked perfect! Thanks for sharing!

[@OhYeahAboutThat]

jono7183 I’m glad it helped!

[@daigosaito888]

I actually like my ‘water tanks’ It keeps the weight low, good for superior cornering

[@crustynolzz4218]

Thank you so much I’ve been looking everywhere for something that addresses this issue. Cheers.

[@heylo232]

I was looking for the holes for about 10 minutes before I looked your video up. very helpful! thanks!

[@OhYeahAboutThat]

heylo232 glad it helped!

[@TheZeroLatitud]

Thanks for showing this. It just happened on my NB and I thought I would need to take out the door panels to drain them lol

[@OhYeahAboutThat]

I’m glad it helped!

[@harryplant8579]

Thanks for this. Only knew about rear window and fuel filler holes you must keep open so this was a surprise to learn. So today I jacked my Miata up and opened all the drain holes along the slls, some were tough but mange in the end. Lots of water came running out which no body in the car had ever heard sloshing about like yours did, Fortunately all inner flooring has always been dry. Thanks Mate.

[@OhYeahAboutThat]

Harry Plant glad the video was able to help!

[@pushhrodd01]

Good choice on doing this. Theres a very big chance that your rocker panels were going to rust badly because of the ester stuck in there

[@charlesmcgehee3227]

Reminds me of the old days when I could take a proper piss!. I am going to get my small screwdriver now.

[@OhYeahAboutThat]

😂. Thanks for that!

[@BlakeGibbons]

Facts 😂

[@jamesrobinson1700]

I was having the same issue. Thanks for the video! Helped me fix it.

[@fisimedia5391]

Thanks for the video we currently have 2 na miata's and both of them are in need of this .... this will definitely help out.

[@TheAdventureAuto]

You gained abut 20 HP from that mod :D

[@andyvaid69]

Ok Change rain rail..bottom of rear screen. .very easy Drill all drain holes slightly larger . mazda did a factory recall to do this.zinc em up. Spray internal sills with. Por 15 or dinitrol.

[@Aidanburns13]

how do you get the por 15 in there

[@mgee6786]

Those two points in between is where the jack is to be placed. You must have a rain rail drain issue. To have that much water in there. Yes make sure your drain rail drains past the point of the underside so the tube is exposed to the underside.

[@OhYeahAboutThat]

Most likely. I replaced the rain rail when I did the top. The aftermarket rain rail was garbage compared to the worn factory one it used to have.

[@DanceGeekRob]

I have an NC so I don't really get where that water is coming from, but holy cow that's a LOT of water in there! My NC is leaking and I've spent over $600 at the dealer getting service to find the leaks and fix them.

[@OhYeahAboutThat]

Either way it’s a good idea to keep those weep holes clear! Thanks for the comment.

[@Valdarious]

Wow, I have had 3 Miata's and I have never heard that much water being trapped, lol.

[@Left0verCuRry]

Check your drain holes near both the seat belt towers. Usually they clog up and water gets into the cabin from behind the seats then onto the floorboard.

[@OhYeahAboutThat]

Left0verCuRry yeah, at least one of mine was clogged solid. I snaked them with a coat hanger.

[@thoughtloop1737]

Thanks man! I just got the water sloshing noise in mine after heavy rain.

[@OhYeahAboutThat]

Thought Loop great!

[@mr.lostmyaccount4721]

I wonder if there is a way to make the holes just a little bit bigger so the water can come out a little easier

[@OhYeahAboutThat]

Sure. Just pry them open a bit more.

[@sthpac69]

Thank you for this info. I looked under my Miata for what you just showed. I was looking for a plug of some kind but now i see. I will not hear that sloshing anymore.

[@OhYeahAboutThat]

sthpac69 glad I was able to help!

[@UndergroundTrev]

Wow!!! Can't say I've seen that before. Sounded like a wave pool from a science class. hahaha

[@Akhorishaan]

Thanks for the video, helped me solve my own sloshing issues.

[@OhYeahAboutThat]

Akhorishaan great!

[@AndrewLeet92]

That was too satisfying to watch

[@keithnewton8981]

sounds like a small ocean in there. na and nb both have this issue . that's not the rear drainage points clean the rear from the top and you will see they are not drain points. you need to completely dry the car out and do the roof drains

[@jasonsabbagh5993]

Top looks like it smoothed out, looks good

[@terryloweh]

looks so satisfying. did the same thing for my car too.

[@OhYeahAboutThat]

Terry Low a Miata? I'm glad there won't be any standing water in mine when it rains. Now, I need to fix the weather strip leaks!

[@robinforrest7680]

Hi there. Love your vidéos. I have a rhd uk model 1996 1.8is (red too) I hear on your vidéo around 6:33 the same really annoying vibration I get at between 2500 and 3000 revs. I've searched everywhere but still cant figure out where its coming from. Any ideas ?

[@_crg_]

Robin Forrest when driving where your left leg is (uk) near the centre console where there should be a small cover. Puvh there and see if it stops

[@IntegraDIY]

it actually sounded like some calm soothing waves at a tropical beach! all you needed was to recline the seats and have a coconut with a straw through it.. paradise:) lol just messing man good fix!!

[@OhYeahAboutThat]

Integra DIY ha ha, right! At least our SoCal cars won't rot like the rust belt cars!

[@IntegraDIY]

Very true, all we worry about is maintenance. Other places have low mileage cars rusting in half lol

[@IntegraDIY]

Look up someone called Mustie1 he's one of my favorite youtubers

[@OhYeahAboutThat]

Integra DIY subbed. I'll start watching his videos.

[@miatakid9409]

You guys are VERY lucky. I live in New England and I bought my Miata a couple months ago. It has 96k miles on it and had some small rust issues but I fixed them. Cars here are a pain in the butt because all the dang bolts are very rusty and snap when you try to remove them, but oh well, it is a project car :)

[@mick0846]

I have a 2002 mk 2 with the same problem. Is it the same to empty the water ad the mk 1

[@OhYeahAboutThat]

Yes. Same procedure. I think the water comes from the rain rail drains entering the rocker panels.

[@ytnym]

What am I looking for exactly? I find the jack points in the pinch weld, but the surrounding area (I felt around probably about a 6 inch diameter circle) just feels like solid metal - nothing that will get opened up by just some light prying with a screwdriver. It looks like you are working just behind the pinch weld - is that right?

[@OhYeahAboutThat]

ytnym yes. There are two weep holes, as shown in the video fingernail, that you open with the screwdriver. Yours should have them unless your rockers have been repaired and they were somehow covered. They are meant to drain water but mine were clogged.

[@ytnym]

Thanks! I found them, didn't realize they were *in* the pinch weld.

[@gamemoments8702]

my 90 miata. when i hit brakes hard. i can hear a wave of water up towards pedals but not wet anywhere. probably stuck in rockers haha. mine makes the same noise

[@OhYeahAboutThat]

GameMoments easy fix if that's the problem!

[@gamemoments8702]

OhYeahAboutThat. Yea i actually jammed a screwdriver in them this morning. both sides peed for a couple mins. haha at least its fixed

[@therealspixycat]

Disguise firetruck?

[@its_a_honda]

I just drill 2 hose one in the front and one in the back so it can just all drain out so I don’t have to worry about it getting filled up

[@WhiteTenpenny]

Came to find out where the holes are and turns out I screwed mine up from scraping. 😅 Gonna have to drill new ones.

[@AnthonyDLH]

You literally saved my car

[@OhYeahAboutThat]

Really??

[@fenman20466]

Cheers, found this useful.

[@edtraenkner4274]

nice it doesn't sound like an old waterbed anymore

[@billdrummond168]

Thank you brother

[@aristovdima]

incredibly helpful thank you!!!

[@OhYeahAboutThat]

Dmitriy Aristov welcome!

[@ginarizzo9589]

All cool and stuff but how did the water get in there in the first place?

[@OhYeahAboutThat]

Leaky top and/or top drain tubes. It’s very common. I think both of mine were leaking.

[@ginarizzo9589]

I am getting water driver side only in front of the jack.How do you get to the top drain tube? The top is new and it's dry inside passenger compartment

[@OhYeahAboutThat]

With the top down, there are drain holes on the right and left side, down near the folded frame. You clean them out with a coat hanger. They extend down to under the car. You can google it and see what I mean. It’s very common for those to clog with dirt and leaves.

[@sandroavelino6448]

Thanks so much!

[@CarbsLVR]

Super helpful! Thanks!

[@OhYeahAboutThat]

Jared Sherr great!

[@nickristine2264]

I straight up just thought that noise was my gas tank lmao

[@RoxusRemo]

lmao

[@derickpouliot5548]

My NA does the same thing. THANX!

[@OhYeahAboutThat]

My drain tube came unattached and let water into the rocker!

[@derickpouliot5548]

Holly crap mine did the same thing lol.

[@derickpouliot5548]

It was a pain to get it back in.

[@OhYeahAboutThat]

@@derickpouliot5548 and that’s why mine is still disconnected! Lol. It hasn’t been in the rain since this video was made.

[@derickpouliot5548]

Oh copy. Well your car is in great condition. Keep us updated!

[@BulldogBadger]

No sloshing and 6kgs weight reduction 👏🤣

[@EvangelionJZL]

good video, now I gotta check mine...

[@OhYeahAboutThat]

EvangelionJZL thanks!

[@backpropagated]

lol I thought it was ridiculous you were trying to get audio of the sloshes, I was not expecting two fish tanks worth of water.

[@OhYeahAboutThat]

Yeah, it was a lot!

[@justsaiyansteve]

Dang thanks.

[@psa10hunter94]

It’s a very common problem with all cars

[@nadrojfan]

Once the music stopped, I thought my audio cut out but it was just horrible editing with the voice so quiet that it is not audible.

[@bearlyexplored]

That was bad, glad it was an easy fix

[@peterpedant]

Water may be gone but the corrosion it caused wont be.

[@OhYeahAboutThat]

True, but I can’t do much about that now. This car is now garaged and never in the rain. This shouldn’t happen again.

[@lostboys8297]

Omg

[@goodeggproductions]

That's gonna smell.

[@OhYeahAboutThat]

goodeggpro surprisingly it was clear and fresh, almost Fiji Water-like! Lol. It only rains a few times a year here, so it was just from this storm.

[@goodeggproductions]

OhYeahAboutThat I've decided that mine will be a garage queen. My drain holes might be clogged too, but I'll never have it get wet enough to find out.

[@OhYeahAboutThat]

goodeggpro my GTR is already a garage queen. I drive the hell out of the Prelude. This car will also live outside until when and if I ever buy a different house with a bigger garage.

[@goodeggproductions]

OhYeahAboutThat You have unique problems.

[@OhYeahAboutThat]

goodeggpro sarcasm detected! Lol

[@Prawnleem]

how to milk your miata
