Really excellent helpful video. Among other aspects, I appreciate especially your explaining in detail (sometimes seemingly insignificant to an expert) things that can hold up/worry someone like me with limited experience. For some examples: Mentioning that the shims can go in either way, and how they are held in place. Pointing out that the valves are canted at 22° so don't point the lobes straight up for measuring lash. The orientation of the "E" and "I" stamping on the camshaft keepers(?). Also good to know alternatives, like caliper vs micrometer. And the rationale for whatever. And things that could go wrong. And the level of detail here and for instance in your earlier video on rebuilding lifters--showing exactly where to grab the valve with the needle-nose pliers. I liked that there was little or no music, and everything you said was relevant and useful. Good lighting and a steady camera. My interest is mainly for keeping my '99 in as good a shape as possible given limited money, and if something like valve lash adjusting can help return it to its original performance that's great. Thank you!
I got a quick Mazda related question. I plan on building a 1st or 2nd gen Mazda Miata into a circle dirt track car. The main rules for it is that it has to be naturally aspirated, no VVT and it has to stay under the Mazda brand. What motor would work best for my regulations? The competition is dominated by K series powered Civics and I need something that would be able to make the same kind of power output that they are reaching. If it has VVT the timing has to be locked.
It can 100% cause a misfire because it’ll leave a valve open, causing a loss of compression on one cylinder. Had that happen on an old head of mine many years ago.
@@NappMotorsports okay, the only other quirk is that it only happens when my car is suuuper hot like if i go turn it on now and drive on the highway it wont miss. sorry for asking you to diagnose my car lol
I just adjusted my lash, my intake camshaft rotates fine but there is no clicking from the valve spring pressure, any thoughts on why I can’t hear the cam switching over as I turn it?
Weird how at 12:00 min it’s 3 hours long.
😂😂😂
One of the best Miata channel out there
Thanks man!
For real!
I'm working on two NA's and planning a swap for later, and most time I wonder how to do something I end up here!

Happy to help! Glad you liked it.
Amazing content-thank you for this excellent information. I need to do this
Glad it was helpful!
16:40 something I've always wondered but never known. Thanks!
👍🏽
This was fun. Thanks. Reminds me I should check mine....
Haha thanks. Always a good service
Thanks, waiting for the shim under buckets video.
I’ve really gotta get to that haha
Can't wait for your Shim Under Bucket video. When are you posting? 😅🍻🍻
Waiting for a head to be finished so I can grab a video. The one I recorded wasn’t great.

99-00 but it’ll struggle to keep up with a K series.
Hello, is there a tool or a method to do this on the vehicle without removing the camshafts ? Thanks
Nope
do you think these being badly adjusted could cause a cylinder #1 misfire? id think it would be all cylinders.

It’s likely fine. I wouldn’t worry about it.
Well, I've decided to buy a bp4w project motor formy NA. Goal is 180-200 hp NA motor
So i may actually nerd this 😂
You should definitely do this.
How come 90-97 don’t need to do this ?
Because they have hydraulic lifters instead of solid ones. Can't set lash on a hydraulic lifter.
Is it the same clearance for the msn?
MSM I’m assuming you meant? Yeah it would be the same.
@@NappMotorsports thanks! Yes, the autocorrect changed msm lol
Toyota had to a 2/10ths shim that you could have used on the 0.1248 😉
Availability was the issue
👀 fix my 99 🤣
Bring it on over.
