I’m in the process of assembling my first rotary engine. And came across the same thing, though it was weird. Being my first engine just thought that’s the way they were and it would compress in the housings. One thing I did notice was I had a side seal that some how it must have deformed and it was scraping the side and not allowing for it to spring back. Thanks Jon for what you doing helping guys like me.
I am so glad you uploaded this video, I have had the exact same thing and was just about to stack my rotors (figuring this was normal and they’d sort themselves out) glad I stumbled across this
Thanks Jon for making these videos, I’m currently building a 13b for my RX7 and your video regarding the factory timing marks on the front pulley, and the video regarding pressing bearings in and out of rotors and this one have probably saved my build.👍
Nice catch ! Can you make a video about the how the oil system works street vs race ? Pump , bearings, regulators , thermal pellet, internal vs external lubrication !!! I'm sure alot of builders are thankful for the knowledge 👍✌
Can do mate. There would be a lot of content just in what you’ve just said, but should be able to break it up into a few different topics 🤔 I’ll add it to my list 😎
Nice video, Even back in the 90's doing builds, one of the first this I was shown was to check all side seal springs sat the same. You would get batches of springs that were soft or flat like the ones you had there.
I don't think that will matter once the engine stack is torqued down the spring tension will even out. If this was an issue there would be many brand new motors with low compression and it would be well known.
Had the same problem here in NZ over a year ago and mazda was not sure what had gone wrong 🤷🏻♂️. Few months ago i had it happen again with 6 being a good height and 6 being as low as your low ones haha. Must be a bad batch surfing around??
Great video once again thanks. I plan on buying some of the extreme rotaries gear for my next build (bearing tool and apex seal groove file), you said on another clip that you stock some gear. I don't have FB do you have an email I can use to contact?

Thank you! I'm in the middle of my first build. I'll be checking my springs.
Wow.... very noticeable, factory needs to pick up their game.. 👍💪
Had quite a few other engine builders track out to me after watching the video to say they’ve found the same thing 😬

Thank You, I may be in the process soon and needed to know this when I geteverything ready for the new build.

Thank you so much! I never noticed this before! Might have saved me engine
Great video, quiet easy to notice when you’ve pointed it out, good bit of preemptive check!
Thanks mate 🙏🏼
He’s back ! Yes !

Thanks for the positive feedback Corey 🙏🏼
I’m glad to hear you got something out of the vids 😎👍🏼
Good info there mate great for the bench builders 😀
Thanks Tiger 🙏🏼🐅

Fingers crossed 🤞🏼 Mazda picks up on it soon (if they haven’t already) & rectifies the problem
Next video on how to resurface housing with that roller 💪💪
Thanks for the idea 💡 Ed 🤔
I’ll do a video about that in the future for sure 👍🏼
Wow good catch, I have new fd side seal springs in the bag and all seem dodgy🤦🏽♂️ maybe a shipping problem?
thanks
Need more videos !
Hey Jon, I appreciate the vids. Really would like a clearancing vid on house to check parts of they can be re-used etc. Bearing install etc also
Hey Hussein. Rotor bearing install video is coming next 😎
+1 for a video on measuring parts to see if they are still in spec. Great videos Jon!
👌👌

Definitely looks like these ones were made at 4.45 pm on a Friday arvo 😂

Like the MAGA sticker on the wall!
And I’m not even an American 🇺🇸😎😂
