One day I will have my own channel, with the RX-7 I just got, and that car and I wanna make it down to your shop to thank you for starting me on this journey with these awesome cars.

[@Leo9ine]

Dude it dude! I'll subscribe to you. About to rebuild my RX8 for the first time. We got this

[@daleredes4301]

I’ve seen people build these engines differently from how you do it. I’d rather copy and listen from your methods. I appreciate the way you explain how these engines are handled

[@missingpiece2071]

By far the best information I've seen on KZbin for rebuilding a rotary

[@sonoragingerdoodles]

Watching for the third time! About to build my 1990 13B TII to be fed by my 7" Camden Supercharger. Thank you for sharing your knowledge!

[@AvoiidTheVoiid]

So exited to watch this, thank you for all the info you give man! You’re a life saver in the rotary community, appreciate all you give. Keep it up!

[@jeremybarr5415]

Its awesome that you go throught the trouble to explain in detail. I have searched and searched and none have gone to the level you have. They provide alot of info but dont take the time to go in depth like you do. Just watching your video anyone could rebuild this thanks to your teachings. I have my rx8 engine out and apart only to find the housings are pretty bad off due to chatter and chrome chip off. But once i find good ones i will definitely be watching this video multiple times

[@brandon_fd3s]

Good stuff for sure. I’m in Cookeville Tennessee and love seeing a local channel on here.

[@StreetTrial38]

Been over 10 Years since I saw someone with Osiris shoes ahah! With dat one, i'm now ready to turn my old baby 12A to a new piece of steel who's gonna move my lil Blue RX7!

[@RADPotential]

Skate shoes hold up the best in the shop man. Despite no steel toe, I prefer them to boots!!

[@VictorMPR]

I wonder why Mazda never went to MLS type gaskets in place of rubber seals. Especially when they are exposed to so much heat. I’m definitely saving this video for when I rebuild the 13B-MSP. I know there are differences, but generally should be very similar.

[@RADPotential]

Rx8s have 3 oil control rings. 2 rubber and 1 scraper. Plus one more tension bolt, side seals and corner seals are different as well. Otherwise it's the exact same process to stack

[@thepcmrtim]

Just dropped my assembly off to the balancer today, I’m so excited to get it back I’ve been so paranoid of screwing up my build but these videos have given me hope

[@jo-qp7mz]

Me too! I watched your videos too lol small internet world

[@thepcmrtim]

@@jo-qp7mz dude…looking at this comment now is crazy to me I ended up building the engine and it runs like a dime to this day 😂

[@jo-qp7mz]

@@thepcmrtim I seen that! I left some comments on your channel! Love the na turbo build! Im cutting my side seals now.

[@cyan9ne924]

I plan to buy a rotary powered vehicle soon, either a 1980's RX7 or really any year RX8. Your videos along with CarThrottle's "Living with a Rotary series" (UK KZbinrs), have really helped me understand how these engines work and what sort of maintenance I need to expect and even how to completely rebuild an engine if need be. I greatly appreciate the time you take making these videos and taking your time explaining things. I was wondering if you might have some input on which car I should buy. I'm mostly worried about being able to source parts for either engine.

[@drkrobe1302]

As well as warm soft-seals would warm metal parts benefit from warmer tempt

[@machinis]

Thank you so much for making this video. I have an FD that's been sitting in a garage for over a decade and it's time to bring it back to life.

[@EASTCAMDEN4LIFE]

My 85 SE has been sitting since 2002 😭 now I'm getting prepared to bring my baby back to life🥰

[@chronicnugget5595]

If you ever decide you don't want to or know someone else with an RX-7 I've been dying to start a project car that isn't 20k for a rolling chassis lmao

[@Leo9ine]

​@@chronicnugget5595just grab an rx8, it's the superior chassis anyway and they're $500 vs 20k. Not the superior engine, but REW fixes that

[@destra1257]

So far I've been loving this channel. Im about to rebuild a Rx8. Although I'd love to see a video about the Hybrid 13B renasis Idea. GSLE rotor housings with the 6 port side housings. I'd like to know if it could possibly be the best way to keep and reliably boost the renasis. Especially with less heat

[@RADPotential]

Kyle Mohan just did a video talking about doing this exact thing. I dont really have the means or desire to build one for me personally. So I'd check his channel and see what you can learn. I'll be following along as well over there!

[@rx7rocket]

My hack for a tube of rtv is to poke a new hole in the tube each time I want to use it and it will seal back up.

[@dimikraa1135]

this is likely the best content for rotaries ever👍👍👍thank you a lot!😊

[@drd1924]

Great video showing lots of the little tricks to watch for....Thank you

[@DBD510]

Knowledge transfer. Thanks for the info

[@bubblegumturtle213]

Do you work on customer vehicles ? Where you at

[@theccwdad]

Probably one of the best engine assembly videos ive watched in someones garage. Any type of engine. I can tell your an engineer when you work on stuff. Im concerned about finding 12a engines and parts if I get an fb. I am not wanting to swap it but there isnt much out there for the 12a engine parts wise. Am I wrong? Why isnt there an insert or something to save those old housing. Mr rad potential engineer sir, I see potential for a rotary engine parts company. Then branch off to plastics and remake interior stuff for old jdm cars. Nissans hondas toyotas mazdas molded plastic interior parts and engine components for the boys❤

[@theccwdad]

There are companies for old powerstroke Ford diesels making random commonly broken interior parts. They're doing great can't keep up with the demand.

[@adrianharris7127]

What a fantastic video much appreciated 👏

Best rotary vids

[@jeffgraham8474]

Great video!!

[@mickgrose6743]

Great stuff dude. Lots of info. Very helpful tips. Always a tense time building engines but so satisfying when they run.

[@madangryfisherman]

Informative vid.. thanks heaps

[@DavidLouisVIP]

Thank you very much for this video

[@_deadpool_reynolds_]

Cool video

[@IconGarage]

Did you rub any oil on the inside of the housings and on the irons? I didn’t catch it in the video. Just wondering if the apex seals and oil control rings are a little dry adding to the resistance. Good video by the way!

[@RADPotential]

I typically don't put any excessive amounts of oil in the engine during assembly. I'm thinking that is a contributing factor accompanied with the brand new oil control springs and metal rings

[@dylanmccallister1888]

24:03 I like that Rob Dahm tortures himself and tries to install those before putting the rotor in the housing I think i would still put the dowels first just for me so i know I'm not screwing up my coolant/oil gasket i haven't done this before and very nice hot start RX8 keeping coming up There is one right now for 3k from the original owner and its yellow with 66,000 miles on it and a hot start issue. Stuff like that in that price range pops up constantly, very very clean cars just rotary issues and regular people are scared so good for me That could be a steal or a catastrophe and needs new housing but i cant see that from the outside

[@dakotamedlin48]

Where did you get the clamp?

[@DavidWilliams-xt9vq]

I really enjoy the show. Can you recommend makes and models of racing seats for RX8 series 1? I think i saw you had installed some Sparcos. Thanks

[@vytauskas93]

Just finished my 12a rebuild a couple days ago! Videos like yours are so helpful, and it was reassuring to see this and have another confirmation that I probably didn't screw it up! Lots of compression in mine with spark plugs in, big chugs and wooshes - I figured that was a good sign. Do you think too much can be harmful or a sign that things didn't go together appropriately? Probably need to get a compression tester and see for myself. Hanging out for your vid on that! Cheers mate, from Australia.

[@KenBober]

Great timing, just ordered my master rebuild kit from Atkins. My 13B has about 60k on rebuild from mazdatrix in cali but previous owner autocrossed it for 9 years. Rather do it early instead of a catastrophic failure.

[@RADPotential]

Heck if it has good compression, Id just keep running it!

[@KenBober]

@@RADPotential the thing runs beautifully but it's smoking a fair amount. It's definitely oil. I did a omp delete and I'm consuming a crap load of oil. Not leaking anywhere. I always park in the exact same same spot in my driveway and no spots other than coolant. Radiator is leaking. Smokes more while going down a hill in gear and not using the throttle. Not a smoke screen but definitely more than 2 stroke oil.

[@anthonytodd8815]

Thanks, I've never dismantled an engine let alone a rotary engine. If I can't free it up, will it even come apart? Also, it's out of the car so what do you recommend I secure it with? These questions probably seem pretty juvenile to you but are major issues for me. Thanks again for your feedback. I'm impressed with your knowledge and craftsmanship on the cars we love!

[@RADPotential]

If it's just on the ground, try strapping it to something, maybe a long board so it won't rotate. Or even if you and a buddy just hang on to it tight. If it won't free up, just start taking it apart. All the small stuff will be pretty stuck. There is a disassembly video on the channel if you can't figure it out!!

[@anthonytodd8815]

@@RADPotential Awesome, I'll give your suggestions a try. Thank again and keep up the great work!

[@SamKader-v5p]

Question if you use a dab of super glue on the edges of the o rings and seals to keep them in place while assembling would it hurt the engine?

[@rubenmalfliet7621]

Didn't you put rtv on the botom of the center iron?

[@anthonytodd8815]

Morning, if I'm bypassing the heater core, is it neccessary to have a thermostat? I'm trying to fill the block with antifreeze and was wondering. Thanks again for delving where others do not.

[@RADPotential]

I would run a thermostat for sure. Regardless of the heater bypass or not

[@eddievasquez1964]

Love the vidd 😉👍👍👍

[@ADudesRotary]

Is it better to have a couple of dry runs (eg without seals, and no torquing) to get the hang of assembly ?

[@RADPotential]

Yea man!!! You could totally dry stack engine and make sure everything is solid!!!

[@ADudesRotary]

Thanks for the video and effort you put in to creating a watchable and informative package.

[@rauldcardos7513]

I have a rx8 with relatively low compression, still runs but struggles to start hot. Unfortunately due to a new house project i have to delay the rebuild for now. But i was thinking since im on a real budget atm, if i take the msp apart and put it back together with new seals and gaskets, would it increase the compression? (assuming the housings and iron’s within spec) I mean just for learning purposes it would be beneficial for me but not sure it’s the right thing to do for the engine. Great Vid btw shout out from the UK 😉

[@ScottJ175]

Thanks for sharing your build process. I've watched lots of them. All but one do the apex seals like you. I watched one guy who held the seals in with a big rubber band, started the housing on then clipped the band once the housing was holding the seals and dropped the housing home. Your thoughts on such a technique?

[@RADPotential]

I think that's a great way to do it!! As long as you know none of the seals on the back of the rotor fall out. That really why I like to place the rotors before the housings.

[@ScottJ175]

He still placed rotor first. Just had the apexes held with that rubber band.

[@andrewabbott4387]

Are you gona compression test it on the engine stand and if so could you show it please. Great video really loved it thank you

[@RADPotential]

Yes sir. I will do the compression test on the stand

[@andrewabbott4387]

@@RADPotential cool, will that be on video?

[@Buccafurno]

great videos.!! what are your thoughts on OMP adapters that hooks up to 2t oil reservoir to pull clean oil?

[@skyfreakwi]

I didn't see any lube on the center bearing of the eccentric. I also didn't see it hear anything about o-rings on the dowels after the front iron...

[@jo-qp7mz]

There is no hack to keep the permatex tube alive LOL tried everything! That permatex with the tip and it comes out like it's caulking that one is sweet!

[@jo-qp7mz]

It's like a pressurized can instead of a tube best permatex it's like 26 bucks though

[@Thechaoscrusadors]

Is it possible to use vaseline to hold the seals?

[@jasondayberry9906]

Would it help to put thin coat of motor oil on the irons and those housings?

[@RADPotential]

Wouldn't hurt anything. I just like to keep the work area less messy during assembly. You can oil the inside thru the exhaust ports when your done stacking it

[@richiebarrow9169]

Is that rx7 rally car 4wd?

[@anthonytodd8815]

Love your videos, I've got a question if you can answer it. I recently replaced a cooked 13b with another, my question is would it be worth rebuilding and how would I know if it is? It's seized and won't turn. Apparently it overheated, that's how I bought the car. Any input is appreciated. Anthony

[@RADPotential]

Fill it full of two stroke or marvel mystery oil and see if you can free it up? Otherwise take it apart and see what's going on. It will be worth more as known good parts if your able to get the engine apart

[@wrxboy2003]

Do you have a file for that rotor stand thingy???

[@markhutchinson3367]

Nice informative video. I rebuilt my 13BT S4 engine a few months ago. I used the old New Zealand video from many years ago that the old school guys used which were very helpful. Very similar content to what you presented, they do things a little differently in some areas, but more or less the same result. Keep up the good content. You ever think about putting an intro into to your videos with music and also outro at the end?

[@RADPotential]

Thanks man!!! I have thought about intro outro stuff. Just been low on the priority list for me.

[@markhutchinson3367]

@@RADPotential I can understand that for sure. Good quality content is where it's at. The intro with maybe a "sneak peak" of the content gives the viewers (mostly those with shorter attention spans haha) something to look forward to. Here is the New Zealand rebuild video I spoke of just in case you have never seen it. There are 4 parts to it. kzbin.info/www/bejne/iWezeHWridaDn80

[@kevinim300]

couldn't you just rotate/wiggle the rotor back an forth on the iron slightly as you put gentle pressure on the apex seal spring.? bingo.
