- This video is the complete guide to replacing a valve cover gasket on a Mazda MX5 Miata, with either the 1.6L or the 1.8L engines. This goes for all cars between 1990 and 2005, both NA and NB. I go through all the steps of removing the valve cover, from hardware sizes to vacuum lines, to removing the old gasket, cleaning the sealing surfaces, installing the new gasket and using gasket sealer if necessary, and finally, reinstalling the valve cover.

Great video, but it is recommended to not use a screwdriver to lift the valve cover, instead use a rubber mallet and knock it slightly 👌
I watched this right before I replaced my valve cover gasket. Perfect rundown of what to do and how to do it. Thanks!
Glad your aftermarket gasket sealed okay. I've heard so many people say OEM-only or else it will leak, but this proves otherwise. I'll try it with this one.
Great video, very good for DIYers, well done.
This is extremely helpful, thank you!
Nice video! My son bought a low milageg Miata and we appreciate your experience. 💯🙌🏽
Enjoy it, they’re awesome cars!
How did you paint the valve cover?
Good vid, good narration, music just right very helpful, just got it done in SW florida , cost $230- now i know what they did-thnx
Great install, honestly informative, #MiataPower
Thanks for this,I just did mine.Luckily I noticed a loose bolt behind the timing belt wheel that holds the plate on...I can only imagine the damage if it let loose and ended up in the cam area. All went well with no leaks,glad I took on this challenge.
Glad you found that and got it done!
Awesome tutorial
Well done! Just bought a Miata and this is something a shop recommended to be done. Might change spark plugs at the same time
Thank you! I'd definitely do plugs if you're not sure how old they are. Old or fouled plugs can make a car run significantly worse. Good luck!
thanks CrashedOutCars! appreciate it man
You’re welcome! Glad this helped!
Purchased using your link! Your tutorial was great and you deserve the affiliate earnings!
Thanks!
Thank you! I appreciate that!
Thanks Buddy, I will be following.
You're welcome! I would recommend sealer on the cam cap corners
Nice! I personally recommend removing the coil pack when doing this. I've changed mine with the coil pack on a few times, and I ended up rolling the valve cover gasket when putting the cover back on which I didn't notice it til I saw my valve cover dripping oil a week later. Also, my flesh paint on valve cover got scratched when trying to wiggle my cover under the coil pack's bolt bracket. The lower coil pack bolt isn't that hard to remove with a 12mm extra long flex-head ratcheting box end wrench!
Not a bad idea! So far mine seems to have no leaks, I’ll continue to check it just in case. The valve cover paint on this one wasn’t perfect to start so I just went for it, but removing that certainly would have made things easier!
I’m having the same issue right now!
Great video! Most people are so scatterbrained doing one of these tutorials and constantly backtracking every other step. BTW replace that radiator ASAP. It should never get that brown.
Thanks! I like to keep all my tutorials quick and to the point. I’ve replaced the radiator, I know it’s a ticking time bomb.. mines been this way for 4 years and I just got lucky. The tutorial on that will be out soon!
Did you ever get a leak from skipping the silicone?
every time i watched this guy's video i always click like. he replied to every comments that people commented
You the man, thanks for your support!
That was a pretty good torque sequence I use to go criss cross apple sauce then when I did it the correct way I saw how it settled more in the middle when I followed the oem specs to go back to the middle after the roundabout from the intake side.
I did not see his sequence on video? As that’s what I was looking for? Where did you find OEM sequence?
@@phytphyr google
Miata 1.8 torque sequence valve cover
What do you think about this valve cover gasket compared to OEM. HONEST QUESTION. I tried to find if gates had one couldn't find it didn't want to go felpro
My husband said I couldn't do it, well after watching this I know I can. I have to purchase a torque wrench and gasket sealer and I should be good. I could not tell what tool you used to go around the covers edges on the engine. But I am sure I will figure out something, knowing I have to be very careful not to knick the aluminum.
Thanks
A couple things worth considering when doing this job are the CAS or the plug where it would be if its an NB. Easier to do with the VC off. Also- the big o-ring gasket on the oil cap is $4 and usually they're old and flattened leading to an oily ring around the oil fill hole. Also- good time to pop in a new PCV grommet.
Anyone know what the fastest change time of a gasket and cover is?😅
So, did it leak where you didn't put the RTV in the corners?
Nice video! Where might using silicone sealant be necessary for the gasket? I just ordered a new gasket as I'm facing leaks toward the back of my valve cover
Thanks! The most important places are curves and contours where it's tougher for the gasket to seal. The cam cutouts and the CAS cutout and all corners will be a good place to start, you won't hurt anything if you add a bit wherever you see fit as long as you don't add so much that an excessive amount gets into the engine. Best of luck!
@@CashedOutCars awesome thanks!
how did you paint the recessed lettering of the valve cover a different color than the rest of it? did you tape it off or do something easier?
I actually hand painted it with a fine brush! It wasn’t quick or particularly easy but it turned out decent
What sux is the bolts are going to break the paint.
What brand gasket is this? Apex? I just ordered an Apex one for my nb2. Also how did it hold up? And do u wish you used sealant in the gasket grooves?
To be honest it's been a while since I bought this gasket and I can't remember. I would recommend gasket sealer around the cam cap corners, but it doesn't need it elsewhere. Good luck!
what about the CAS?
I need to replace the gasket on my 07 NC1. Will it be similar to the NA?
I haven't done an NC and I'd imagine there might be a bit more stuff in the way but the general process will likely be similar. Good luck!
The Mazda instruction books says that is necessary to apply sealant to avoid leaking
I had good luck doing mine like this but sealant will only help when done right! Thanks for letting us know about the repair manual!
Yeah I found this out the other day 🤣
What tool is he using to clean off the remaining gasket stuff? I mean the white plastic thing
I used a butterknife wrapped in some paper...
Kinds looks like that :)
I like the white
Thanks! Me too, matches the rest of the trim on the car nicely. More to come👀👀
@@CashedOutCars has she stayed white ? I've been considering it but under a hood might be hard to keep clean? If I'm wrong lemme know, Cash!
what about vvt cars?
Iam kinda now to this so how do you measure how hard you have to torque it down
A torque wrench! amzn.to/3eQ5F8e
So I blew the vacuum hose on the rad reservoir side and it puked oil all over everything and almost cought fire ..... throttle got stuck floored I'm hoping that it's not cooked because of the crazy sheet I did to it lots of stuff done rollbar coilovers rims with runflats exhaust + brand-new interior I don't know what is what with motors I can do brakes oil changes and so far that's all I can do but the new issue I'm sure that I have a few things to do/learn
What paint was used to paint the valve cover gasket
I used high temperature engine paint for it!
Did it go alright without the sealant around the gasket?
I didn’t have any problems with it but I’d recommend putting a bit around the cam caps and CAS cap just to be sure!
@@CashedOutCars okay nice one! Thanks for the reply! 👍🏻👍🏻
Thank you my friend that was a great and informative video :) I was wondering how it turned out just using the store bought gasket with the sealant you decided not to use??😊
You're welcome! It held up well for a few years, but did leak eventually so I replaced it and did seal the cam corners
I did like the video but noticed you did not tighten up the 12mm bolts
does this help lifter tick?
Likely not, the best way to solve lifter tick is to run a good oil and ensure you have enough oil. Lots of people run Rotella T6 (myself included) and say it helps. If it doesn't go away I honestly wouldn't worry about it, these motors love to tick!
i have a 93 miata with 50000 miles, and i don’t think the valve covers ever been off since the factory put the car together. i wonder how bad the gasket is lol. i’m replacing it today
Is it obvious which plug goes to which cylinder when putting them back?
It’s fairly clear, and you can find wiring diagrams online if need be. You can always label them to be sure!
It's slightly different on NB2
What’s different about it? It’ll help some people out if they know!
What is the torque pattern please?
This should help you out www.google.com/url?sa=i&url=https%3A%2F%2Fforum.miata.net%2Fvb%2Fshowthread.php%3Ft%3D677251&psig=AOvVaw361fXhx4FiU1-bsI-69ibf&ust=1614975236741000&source=images&cd=vfe&ved=0CA0QjhxqFwoTCICsktu5l-8CFQAAAAAdAAAAABAD
You forgot the dabs of RTV that should be put in the "corners" of the lower mating surface at the cam caps and CAS cap.
He mentioned it in the video.
What is the torque spec? English is not my first language it's kinda hard to understand properly with generated subtitles
it was 6 foot pounds
I thought you’re supposed to tighten the bolts in a crisscross pattern
Year later and here I am back , because I messed up 🙄😂
You seem to forget adding some sealant at the corners of the gasket around the front and rear caps
I mentioned it in the video. Mine doesn’t leak as is, but if you’re worried about it, yes you can
You forgot the rtv in the corners
I don't know about having that cone filter RIGHT NEXT to those HOT HEADERS.
That intake was on there for sound reasons not power, the car is turbocharged now anyway
@@CashedOutCars Sound reasons? As in, poser, 'hey, look at me' reasons? Lose power, gain sound? Is that the logic?
No one said you needed to put one on your car, I enjoyed it while it was on there. Everything isn’t all about specs and performance
@@CashedOutCars 'Everything isn't about specs and performance'. So it's about making noise instead? ☻
Building a car is about doing something that you enjoy. We have hobbies to entertain ourselves, make friends, and make ourselves happy. If you enjoy the sound of something of a mod, be it an intake, an exhaust, a turbo kit, or a sound system, then it should be done
I want to know who tf downvoted this video. No reason to at all
Agreed :) Thanks for stopping by!
This tutorial help me a lot.
However, I opted to wash the hardened oil on engine bay and proceeded to ruin my cat converter by leaving some water into spark plug well closest to firewall
That mistake cost me 1k on repairs cat had catastrophic damage afte a 30 mile drive
This drove me absolutely hate this car.
That sucks, but at least you will learn from the mistake.
Someone scammed you, 1k for a cat?
No specific pattern required when tightening them back down
There is a specific pattern, if you google Miata valve cover bolt torque pattern it will come up
hmm
Dude, you’re not even following the tightening pattern. Hack.
I disagree, I followed this recommended tightening pattern
