Looking forward for the next video! Currently rebuilding my 1.6 for the first time. Thank you for hard work 🤟

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

Thanks for this very useful tip. My tick was very intermittent and hasn't come back since my last oil change.

Good video, very straightforward.

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 😁).

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 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 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.

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!

Thank you 🤙🏾

Great video.

Great video! I use Castrol Magnatec and I dont have any ticks anymore

thanks napp this is a game changer! i look foward to trying this when i change my belt and pump. But i thought mazda specd out 5w30 for na miatas?

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.

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.

I like to run rotella t6 with 16 oz of marvel mystery oil in the winter. No noisy lifters for me

Does the hole in the lifter have to line up with the little hole in the case? Or does this not make a difference? Great video!

This was easy to do

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!

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!

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 👍

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

شكرا للك thank you

Thanks for VDO, Kindly please show me engine sound before do this then sound after do this.

Hi, do You know, wich the exhaust/intake side lifter? - they differ in the inside - thanks!

@Napp Motorsports what kind of oil did you soak them in at the end?

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 ..

Awesomeness brother thank you !!!!

Any news on the 2 liter ITB motor?

It’s so much easier to just put the wrong oil in.

Is this the same instructions for a 1995 Nissan Sentra 1.6L ?

I have a 2001. Do I need to adjust the valves?

do you use a specific oil?

👏

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

Doesn’t swapping a 99 head also fix the issue?

Lol....a brotella guy. When I first hear that, I was like....uh no. 😂 This what we had to do to earlier Hyundais that used mistu motors.

This really fixes the tick? I've got the timing belt off, might as well try it

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.

Or just substitute 1qt of oil for 1qt of atf when doing oil changes. It'll clean out the engine and keep it healthy.

ok

Why not just buy all new ones

I didnt know Mac Miller built miatas

Definitely gonna try this when I rebuild my head, until then I remain a brotella guy🫡 Great vid man lol
