Mazda Miata Fan - Episode 6 - Valve Cover Gasket Replacement
Вставка
- Опубліковано 26 сер 2024
- In this episode, I demonstrate how to remove the valve cover, replace the valve cover gasket and replace the valve cover on a Mazda Miata. It's geared toward the NA and NB models.
I also cover inspecting the timing belt and painting the valve cover while it's removed from the car.

Post-Production Notes:
* At the end, I said that if you follow these instructions you will have an "oil free top of your motor." I meant to say that you would have an "oil leak free top of your motor."
Just about to do a gasket change. This is the best tutorial I have found, no crap no "yo dude" just straight forward how to do it info, cheers.
You produce the best video tutorials for miata maintenance, thank you so much. PLEASE PLEASE do a water pump/timing belt replacement episode or episodes as I have yet to find any that really walk through each step as clearly and concisely as I KNOW that you would. You rock!
I'll be doing this tomorrow! Thanks for the very detailed video. You've got yourself a new subscriber :)
Best tutorial ever! Just completed it on my 99 NB. So helpful! Just be aware on the NB that there might be a wiring harness connector on the passenger side, and that there might be a sensor on the front passenger side too. Cleaned it and painted it a beautiful Gold. Great contrast to the rest od the motor! Thank you so much!
Also: its a great idea to buy the parts on RockAuto, great prices! Its also the perfect time to change plugs with the valve cover off.
Edit: DO NOT BUY A CHEAP GASKET. ALWAYS BUY OEM. AFTER MARKET GASKET WILL LEAK AND/OR FAIL. I JUST REPLACED MINE WITH OEM AND SO FAR NO ISSUES!!!
Very thorough work! Sanding off the tops of the cover badge would give it a little contrast and sparkle. Great reason to do work yourself - shops do not clean parts like this.
YOUR GARAGE IS AMAZING!
Yes, the gasket is visable from the sides after installed, But it does not stick out of the sides. It is a thick gasket that fits into a channel on the valve cover as shown and the cover is not screwed down so tight as to completely crush the gasket.
I just changed the valve cover gasket on my friend's Miata with ease! Thank you for this and all your videos!
Nice no frills video, very helpful to the extent I’m changing my seal tomorrow.. subscribed !
Used this video when I did mine a couple weeks ago, haven't started it up yet as there is still to much snow in the ground, but I think I got it done right! Thanks for the video!
I want to thank you for all these super informative videos!
Thanks, helped a bunch. I was doing my 02 SE so I ran into the speed bump of the VVT parts and would've preferred to also see you take off the plates on the valve cover. No worries though! Thanks again
you are absolutely awesome! so detailed and clear. best auto maintenance video on the web. thank you!
You convinced me to paint my cam cover Miata Red (or equal)
Thank you so much for taking the time to make and edit this video. It's very clear and precise. I really appreciate it.
How long should you let the gasket sealant cure before you start your engine? Certainly not right after you install the valve cover back on??
Harbor Freight has a inch pound torque wrench for $20. Pickled up a slightly different model at the store that was unfortunately just 1/4" so you might need an adapter for your sockets.
That arcade looks like The Flipper Room in Concord, CA
I like the organization and thoroughness of your production. And the editing is good as well. One thing that I noticed is that in some of the interior shots it was too dark to see what you were shooting, Perhaps a small light would help? And some of the macro shots were a little fuzzy. Actually the light would also help those shots as well since it will cause a small aperture on your camera which will increase the depth of field. Just my 2 cents.
Thanks for the informative Video, was a great easy to follow video. I need to teach you how to paint though ! lol
Keep up the great work.
Thanks so much for this. I'm about do the same job on a 2000 Protege.
great video. very helpful! thank you!
GREAT tutorial. You could have even done a two-fer and got the CAS O-ring while the cover was off, to help even more people out :P
great channel and really easy and well explained steps keep it up it's already helped me out a ton
so much work for that, and than you're painting it in light gray... well it's your choice but I would have painted it in the cars colour oder in red. Anyway, nice video and very nice car!!! Keep it going. Greetings from, Germany
This guy is a pretty good multi-tasker lol
great video. when i did this on my 1990 miata, the pcv valve and grommet both cracked and the breather hose cracked. all had to be replaced. this was very helpful. maybe you'd do a video on timing belt and water pump replacement :0)
you dont have to take the front 2 bolts off. you just have to undo the hose the that air intake part. unless of course you want to clean the valve cover
Awsome video. Clear and complete. Thank you!
Awesome video mate! I'm going to try this to do myself. Can't wait to start :)
Do you think you should let the gasket sealant dry and cure before starting? Just curious as I’m doing this myself now.
awesome video, I just replaces my gasket thanks to this video HOWEVER I really struggled with the two bolds in the rear, they were pain because it was really hard to get to them. I also ennded up cracking my breather hose, it cracked right where it plugs into the engine cover, its still okay but has a crack, IS THIS something I have to replace right away? What happens if I do not replace a breather hose right away? thank you!
Does anyone know why he says to tighten the engine cover bolts in a circular pattern as opposed to a star pattern?
Alex Cheng So you don't mess with the geometry of the engine
Feng Shui
It's Mazda spec
Did you have any issues after doing this? I also replaced the valve gasket on my NA and driving it the first time was fine but the second time i heard what sound like sparking from the spark plugs in the back but it went away as it was heating up so i didnt give it much thought. After I was driving for about 5 minutes i lost almost all power and was putting out a lot of smoke and the car wouldnt idle on its own meaning i had to keep giving it gas to stay running but it sounded so so bad. The engine still turns but sounds really bad when it runs for the 2 seconds it can before dying again. I could smell coolant, oil, and gas so i know its not good. I am confused what i did wrong because i used rubber gasket sealant on all the curved corners and the gasket was seated properly in the cover. Do you or anyone have any ideas? Right now I am afraid to touch the car and will likely get it professionally checked out.
Excellent Video. Thank you for sharing with us.
you just made my life easier. great video!
GREAT video. That really helps me a lot. thank you.
Awesome, thanks so much. I will be doing this next weekend.
My PCV valve blew off and spit oil over the engine was thinking that the peddle got stuck rpms wrrway too High..what would of been the reason for that to puke oil
u have your own game room nice
What colour was that engine enamel that you used? Would love to get the same look
Letting it dry, now. Thank you!
No, this has noting to do with coolant. You probably have a leak in the coolant system. It could be a bad hose but possibly a bad radiator or radiator cap. If the radiator or the hoses have never been replaced than they should be due to age. If you want to only replace the faulty part you can rent a radiator pressure tester to help locate the source of the problem. There is another youtube video that shows how to do this on a miata, but a second gen miata, though the procedure is the same.
You shouldn't even use the torque wrench. you are turning the bolt a 1/8 of a turn after the wrench clicks telling you its tight enough. Just an observation.
Chris Spencer what
He kinda has a point. The purpose of the torque wrench "click" is to let the person know that they hit the torque spec. If you tighten past that you are going over that torque spec...
would you be able to make a video of stripping everything in the engine bay and repainting it?
loving the videos, keep up the great work
Said to torque the bolts between 43 to 78. I set mine to 60 and broke a bolt. Will now need to find a way to remove the broken bolt. :=(
Really Helpful Video thanks for posting!!
noooooooooo that beautiful quilt!
Thanks for the well made video!!
Hello there! So I have a Miata a 1995 Mazda Miata Mx-5 and I need to change the brake master cylinder ! but I don't really know if it has abs or not how can I check that out?
just for safety measure, is it okay to put a thin film of the RTV sealant around the whole perimeter of the head cylinder instead of just the corners and the grooves you've mentioned in the video? I just don't want to have to risk having my valve cover leak again, it's a easy job but just takes a long time especially for my Audi
thanks for such a great video and channel! your garage is awesome btw..i bet you throw the best bday parties
Is their any CAS-o ring that you have to change as well?
these videos are amazing!
Just to be make sure, this is for a 1990 miata too?
Great video! thanks so much bro
torquing those little bolts to 72ft lbs wont cause the threads to cross?
4 in the front and 2 in the rear is what you should say for the sealant spots. And I don't think you did the correct order for tightening.
@themx5mk1 Your engine is 1.6L, while his is a 1.8L. Very similar but different engines.
do you have any videos for the NC models?
if not, you should, you're great
mazda maita clutch change next time?
Great vid!
Can you do a aftermarket air intake demo?
Awesome video!
Can anyone recommend some good primer + paint that is available in the UK? Cannot find rustoleum here :(
Is the gasket suppose to show on the sides?
Great how to thank you sir.
Note this won't work on a 02 miata as there's a rebreather on top that is painfully difficult to remove.
Why did you tighten all bolts circular instead of X / star order?
In the Haynes manual for the car, it says to do it in a circular pattern. Star would seem correct but you can't argue with the manual.
Thank you
Awesome garage ! :D
hello!very nice video!i just would ask if this process of paint lasts, because this cover exposed to high temperatures.
thanks!
As long as you use high temp paint, like the VHT Engine paint/primer, it should last for a seriously long time!
Any tips on a 1990? I've done it a few times now and I've ruined a brand new gasket when trying to wedge the cover underneath the coil pack mount and over the exhaust cams rear hump. Holds up fine but slowly leaks oil back there and just received my new gasket yesterday
+Andrew Margello Check you CAS O-Ring. It might be leaking, and is a common oil leak spot.
Is your car manual
I see your cas is on the rightside i own an 92 and mine is the leftside something is wrong here
is that not what the dish washer is for? when the wife is not home
Good vid :)
its 72 in lbs, not ft lbs. If you do 72ftlbs you'll destroy the threads.
you got a very good sounding voice lol, ever thought about voice acting?
1st view. haha. thank you for your great tutorials
Do you have to replace the rubber between ?
It's pretty good to do since it can be cracked or dried etc. This can result to leand and I think loss off power. But if the gasket seems good you can skip it.
Is it ok to leave the spark plugs in?
best to take em out so you can check those while you're there
Generally a good video. However, all pieces attached to the cover, (grommets, wire brackets), should probably be removed before the cleaning. Also, all openings like the plug wells and bolt holes, should be masked so paint will not get in.
3 eco-friendly people frowned when you sprayed all the old oil out onto the pavement.
I accidentally used foot-lbs. woops.
Uhmm is that the Boomers around Irvine? haha
His spray painting technique is scary.
I thought so too, but hey it looked good!
he said you need a wrench with inch pounds. People say the wrong things once in awhile, inch pounds isn't used nearly as commonly as foot pounds so it's just a slip up.
dont replace bolts in circular order. use star pattern
i use that toothbrush
Damn you inch pounds!!!!!
RTV causes more problems than it solves. Just use the gasket.
