What a job. 16 lifters took an hour and half to come apart. None of inside parts would budge like yours. They would turn but not go up and down. I had to fight each one. You’re right though once you see how they work there’s nothing that could get in there to clean the inside. They gotta come out. Excellent video. Thanks for taking the time to produce these videos.
I did a seafoam treatment on mine, (following the Project Farm guy's method). That was over 3yrs ago and my Miata hasn't had any 'tic' issues since. If that didn't work, I would definitely recommend the procedure you're doing here. Saving vid for future reference.
Thanks so much! I’m doing most of my own work on a 1996, and the lifter tick is baaad. Guess this is the next project! I’ll update if I explode the car. ❤
thanks so much for this video, i just cleaned them out by swishing them around in acetone and chunks of stuff came out. i might have other problems that i didnt know about but thanks to you i found it
Much easier way and save yourself time. If your engine hasn't grenaded and is running, add 1/4qt of generic ATF to the engine. The detergents clean the HLAs as well as any buildup in squirter feed passages. This is an immediately noticeable change in sound and performance of the NA engine. ONLY DO BEFORE YOUR OIL CHANGE!!!! OK TO RUN AT LOWER RPM ONLY!!! FYI, not just some random dude on the internet. Have been working on Miata/MX5 specifically since 2003. Enjoy your vids man!!! Lots of great information.
My 1996 Subaru 2.5L DOHC uses these exact same lifters and they're all stuck. Glad I found this video since I'm doing head gaskets and I'll clean the lifters, had already priced new ones and now know spending that $$$$ isn't not necessary. Thanks!!! Just a note that paint thinner is a better/safer cleaner than gas or brake clean.
I'm also a huge fan of fixing and maintaining things instead of throwing them away. And so I found and still find this clip here about the maintenance of the hydraulic lifters very interesting. However, I would like to make one addition, which I consider not insignificant since it has a major impact on the function of the plunger. We are talking about the checkvalve in the plunger. This is hidden under the tiny sheet metal cap at one end. You can now lever off this cap relatively easily with a screwdriver and a tiny spiral spring and a small ball appear. The conical seat of the ball becomes dirty over time due to oil varnish and thus impairs correct function! From hundreds of my own experiences I know that this service can extend the life of the hydros to the full extent, but the wear and tear is evident here too and sooner or later new tappets are simply due! Also and very important to note: the play of the bucket tappets in their bore in the cylinder head! A few hundredths of a millimeter more of a good thing is too much here and the oil pressure on the tappet drops and the supply to the hydros is too low -> rattle or tick!
@@NappMotorsports, .... sure, I can understand that! That's why I've gotten into the habit of disassembling the cap right next to a magnet. The magnet comes from an old wideboard and is perfectly adequate for this purpose... doesn't have to be a neodymium magnet!
Great video and tip for hydraulic lifters - I never realised it was so simple! I run 5w-40 in my turbo 1.6 and haven't suffered any cold start lifter 'tick', but I also did any engine oil flush each year until I put on an oil cooler (Yes, it's a pain emptying the cooler and pipes - so no more flushing!!). Looking forward to the engine build. Keep up the great YT content (not a fan of Instagram 😒, much prefer YT 😁).
Did this a couple thousand miles ago… definitely helped but if your car sits for more then 7 days you’ll eventually get it on startup. A way I did find that works for me is just cranking my car over until I get oil pressure, them fire the it up and I almost never get lifted tick any more. Also why don’t you like rotella!? Its killer use it in all my high rev jet skis and bikes they have had the best results coming back from blackstone.
@@gogobnr3291 I didn´t use this technique. I just changed my oil and it hasn´t returned. Still going fine. I just plan to fix it properly if it ever does become an issue.
I tried this and could NOT get the lifter apart. I noticed that the inner plunger bit didn't have a lip to grab with a pliers, so maybe they are aftermarket ones that aren't meant to be disassembled? Couldn't find much about this online, was wondering if you had heard of this or ever had trouble getting them apart. Ended up calling it quits after 4 hours of prying/soaking/heating and ordered a new set of ITM lifters. Love this channel, you guys are on your way to 100k+ subscribers no doubt!
@@NappMotorsports I have a 95. The plunger does push in and out (and rotates) so I know its not totally frozen in there. My guess is the OEM ones have an O-ring or something that compresses when you pull them apart and these aftermarket ones have some kind of an interference fit and were put together with a big ol' press. I might cut one open and find out...will report back.
Thanks Steph, will be doing this probabaly tomorrow prior to putting my sons engine together. Been putting it off for a while but it needs to be done. Looking forward to the full engine rebuild videos.
Hi, inside the inner plunger on the "nubby end" there is another spring and a little ball, that prevents oil is leaking while engine stands still and no oil pressure comes through the little hole. Is it not necessary to clean this too, to get rid of lifter tick? However, great video and good description 👍
This is the same question I have - I was wondering if the checkball cage and checkball should be disassembled, or if they get cleaned "good enough" without full breakdown. I suppose one could clean as shown, then take one apart to see if there is any residual shmoo inside, then decide. Thanks @NappMotorsports, and thanks for thinking on the same question, @WernerTiffy.
So, my NA6 had a very mild lifter tick that would generally go away. About 3 months ago I started restoring this Miata after planning it out for a year. I rebuilt the lifters just as you did last week and today I started up the car, the lifter tick sounds worse that it ver did now. People online seem to imply it's normal and I needs to run it to prime the lifters even though I already did that when they where out. Although I suppose the oil would have gotten pushed out when I timed the engine. Any thoughts?
Nice, given you've seem to have done many, have you experienced any failure rate: ie tick continues after treatment, and also just wondering if you would ever bother renewing the whole HLA assembly given you have them off ... appreciate you thoughts. cheers
I've done this maybe 3 times total. The tick can still be there, that's obviously a risk, but in my experience it either goes away, or will go away after a few cycles.
Honestly, at $250 for a set of new lifters, this is getting a bit hard to justify. I didn't even bother trying to rebuild mine, just slapped some new ones in and called it a day. I think lifter tick is less about gunk building up as it is the hydraulic bores wearing out and allowing oil to leak past through the HLA. I've ran all kinds of oil after I replaced mine, none of them resulted in any tick even when cold. I can let the car sit for a couple days and it still wont tick now. Worth the investment, plus you end up with new scuff free tops.
I just did this on my 1.6 NA , as it had lifter tick for a while, and I was doing timing belt/water pump. It was much needed, most of them were not moving anymore. I started the engine before putting everything back together, to check for correct timming, and I immediately noticed the difference in sound (though the engine couldn't run because vaccum lines unplugged, so it didn't hold iddle) After putting everything back together, I took the oportunity, while in there, to change the oil. I didn't do any priming, and started the car the next day. When I started it, it had no oil pressure for a few seconds (normal for an oil change I assume), and then the system pressurised as usual. Unfortunately after starting it, I noticed the valve tick (when in front of the engine, not audible from driver seat), so my question is this; Is it possible that air bubbles got in the lifters, during the cranking phase, before there was oil pressure in the system, and now that there is pressure, air is trapped in the lifters thus causing lifter tick? If so, what would be a way to avoid this? Maybe change the oil before and not after next time?
They will drain out when they sit. Just run it and they’ll fill with oil once it gets hot and the problem should go away since they’ve been cleaned out.
Do you think there's any advantage to putting each lifter (disassembled) into your parts cleaner? Or is that overkill/the gas gets every bit of grit anyway. Awesome video!
Humm that’s pretty easy. Besides putting everything back in correctly there’s nothing else? Can’t find the post I read about doing this but they had said something about letting them sit a little. Necessary or miss informed? I figure by time you get them back in and finish the job they’d have lost some oil anyways.
I don’t let them sit longer than it takes to put the engine back together. It’s not critical, the important part is getting and debris out and making sure they move freely again.
I have a lifter tick after warm up....when cold everything is quite....only when hot.... Does cleaning them like that solve that problem !! Thank you mate ..
I VVT swap every miata I own so I don’t have to worry about it coming back because solid lifters. If you change your oil at a good interval it shouldn’t come back.
@@NappMotorsports ATF has lots of detergents in it. On this basis, it MIGHT help to clean some gunk from the crankcase and other internals. Just be aware that most people do this as kind of a last resort so you MIGHT not have to actually open the engine and fix what's wrong. Kind of like Seafoam treatment. Not saying on haven't tried it in a very limited scenario in the past (Chevy 5.3 lifter tick - 350k miles on the new to me vehicle), but I knew what my risks were and definitely didn't drive anywhere with ATF in the engine oil. Didn't fix my issue and I ended up dropping the oil pan to replace the pickup tube o-ring (AKA the real problem). All the ATF trick cost me was a couple dollars of fluid when I was changing the oil anyway. Still wouldn't recommend it for the Miata lifter tick though.
@@NappMotorsports it did fix the tick! I was impressed how stuck mine were. 5/16 stuck solid, 6/16 partly stuck. I had to soak them in gas in my ultrasonic cleaner for 15-30 mins each, to get them unstuck. What a pain since I could only fit 3 containers in my cleaner at a time. Took way longer than I wanted, but certainly extended the life of that engine. When I first started the engine back up, it was way quieter, but still had a little tick. Did a little 1500-2000 rpm for a few mins, and it gradually went away. I assume the cam had to rebed to the lifters that were stuck for so long? not exactly sure, but it's quiet now. Thanks for making this vid, as it gave me the confidence to tear into it

Dumb question: what is it that holds the assembled lifter together? Friction, O-ring, etc.?
