Been a tech for 40 years with zero experience on rotaries who just bought an RX8 with low compression. Your no nonsense approach video is just what I was looking for. Keep up the amazing vids and your passion for these engines.

I like how you broke down the differences and levels of involvement with Rotaries for the general knowledge.

holy cow man I think I now know more about this engine than my local mechanic LOL you're a genius dude!

Thank you so much. I've been sitting on my FC since high school, and I'm finally gaining confidence and insight enough to dive into the engine rebuild because of people like you in the rotary community

I swear this is the most useful/informative channel I have ever watched. Please keep this up, it’s helped me so much

Thank you for this. Really. Thank you!!

Wow man, I appreciate the hell out of you for putting this video and your whole channel together with so much info, its a gold mine for rotary knowledge. I feel like I owe you for this. Keep it up!!

I just love watching rotary videos! Great work man! I can't wait to have you check out the new build I"m putting in my IT7 based car. Keep up the good videos man.

Great video! Thank you so much! As everyone else has said, your approach to this is unparalleled. Please keep making videos for rotaries. The community NEEDS you!

Dude! Thank you so much. This is as straight forward a video about rotary info as I’ve ever seen. Thank you also for that link on the book! I may just find that RX-8 with a blown engine to rebuild.

Rotary legend! I love watching your videos. Getting me ready to do a rebuild when the time comes. Lol

I want to get an FC and was nervous about getting into rotaries but, this made me way more confident. Awesome video, thank you!

This was a great video, thank you for all the insight on motor building!

One of the best rotary channels, you're the best bro!

This video was awesome and I appreciate the fact that it's out here for me to watch a year later

This was great! I just bought a gsl se, runs good but going to do a re build as it has never been done since 84. All the info I needed was here. Thanks dude!

Best video i could ever ask for my m8! Holly cow!

Thank you so much for this video on explaining rebuilding rotary I own 2 rx8 since I was 15 and I’m still learning so much. I love how they sound and feel it’s a different experience and eventually I want to do rebuild shop Bc not that many people do them I guess I’m a dying breed.. but anyways great video and thanks again for your help on explaining in depth ✌🏻

What a great video! Concise and to the point .

absolutely awsome video ..I am a old v8 knuckle head and I am about to head down the rotary rabbit hole and your video was perfect exactly what I needed ...thank you

Awesome stuff! Great info

Bro this is awesome info! About to buy an FB and this totally opened my eyes. I can’t wait now. I love puzzles man, thank you!

I don't even have a Mazda RX but I love watching your stuff man, keep it up!

Just picked up a 85 can't wait to get started on it 🤟

Great Video as usual. Thanks!

Very informative vid man. Recently got a s2 rx8, 8,600 original miles. Couldn’t be happier

Great video man. Thanks for sharing your knowledge!

This is so frickin cool! I have a '79 pops bought the year I was born, been with me ~42 years! It still drives pretty well but does smoke a good bit, pretty sure it's the coolant seals. This video is so dead spot on for exactly my situation it's... RAD! :)

Thank you so much for your videos bro I cannot exain how much this has helped me with the rx8 I just traded my 93 mx6 for , perfect explanation of how a rotary works

Ok, that is amazing video. I'm so glad I got here. I bought my 2010 RX-8 R3 almost 2 years ago. I'm thinking about doing a rebuild on my own, and this video gives me some additional courage to chase the topic, get more info and try to do it at some point.

Incredibly informative and well presented video. As a guy who recently became interested in rotaries and knew very little about the engines themselves, everything was very easy to understand and answered many of my questions! Thanks

Thank u for sharing your knowledge! Very appreciated

Love your channel!, really underrated....

Just crystal clear, I got recently my rx8 and I see tons of videos on engine, this is actually first tutorial that is totally understandable to me. 🥇👍. Thanks

New to me RX7 purchase and great entry level explanation for me. Thanks for sharing

Super dope. Thanks for the info.

Great video!! Don't change anything!!

Damn, i don´t even own a rotary but always appreciated the knowledge about it, got this recommended, your channel is very informative, subbed!

man you are great at explaining it all. Good job!

I appreciate the depth of information in your video. I very much appreciate the time you took to make this video. 65 years old, rebuilt regular engines and transmissions with success. Rebuilding a rotary when you can't get parts ( housings or irons), it seems a little daunting. Have had my car a number of years, going to try anyhow. Really really appreciate your video.

Bro I bought my first rotary like 4 days ago(I've legitimate dreamed about this car) and all I've done is listen to your videos haha thank u!

'Freeze plug' is a misnomer; they are actually casting plugs, the holes used during the casing process to remove the casting 'sand' from internal portions of the casting and then closed with a plug.

Very well explained! Thank you!

Appreciate the insight , thank you very much!

Don't have a rotary engine vehicle, never driven or even been in one. But I think they're interesting, so I am wanting to learn more about how they work and what a rebuild entails. This is a great video! Thanks man!

Your video is very informative regarding Rotary potential failure areas and how they happened. I had watched all the popular videos about the Rotary engine and yours has given me more anxiety than ever as I own an 86' S4 NA RX7 (only 60,000 miles)...😂😂😂 Mine is having an oil leak running down from the Oil pedestal (not sure yet) and perhaps could also be the Oil return line (which is right below the oil pedestal). I need to bring it to a shop to check it out.

Had my first coolant seal leak and this showed me how to fix it, thank you for keeping it plain and easy for me

Great video, just about to import a series 1 from Japan, really helpful to know this stuff going forward

Great video very informative 👍

Very good info I think that’s the best info I got

I make alot of the parts for Formula One engines, especially turbo's. Cylinder Heads. Formula One engines that rev to 23k on the test beds create incredible heat which of course melts normal metals. so therefore we put a liner inside the high heat areas of Inconel 618. of course these engines come in at 5 million $ but it would be interesting to see a garagista do something similar with one of these. very DO-able.

Just binged watched all the Holley sniper efi videos Rx7 series. Really good content. You have my subscription sir.

No one shares this intimate knowledge of a rotary engines."secrets" Thank you for sharing unbiased practical knowledge and experience. Most definitely got a sub!

Fantastic info and video mate! Really enjoyed listening to someone who has the experience and knowledge to pass on to us fellow shed builders( i use the kitchen its cleaner for engines🤣) Thanks alot man from me and the people who dont bother to return the love THANKS!

Great info!

Titanic level rust, that part got me lol

Well done. Fun to listen to....

19:11 ''When shit hits the fan, its creates a giant shitstorm'' Old video but very usefull info! Thanks!

Awesome timing, i'm getting ready to tear down this block I bought to see exactly what it is since noone in my community can recognize it lol that book should come in hand as well thank you for all the info you put out! That Chips Motorsports build looks so clean! I actually stay near that place and they do very good work, looking forward to that build!

Love your vids mate, I’ve subscribed, you’re worth way more subscribers so doing my bit, love me rotarys!!

I have 4 12A’s i want to take apart this summer to see what is salvageable, mainly my 79 12A since it seized while turning over and it’s been killing me why it seized. I love these videos, lots of knowledge in a little amount of time. Well done sir, keep it up.

Thanks for sharing your experience/knowledge with all..... Sadly getting this doesn't happen with puertoricans rotorheads. Anyone fron Delaware?

Great video 🤟

Thanks man,

Thx for your input. Idea like to get in touch and pick. Your brain. On a build

Thank You.

Epic vid bro thanks!

Super helpful! My stock 85 12A is hard to cold-start. I pulled it out of a barn a year and half ago, sat 15 years before that. I know it's only a matter of time before a rebuild is in order, and this helps to set expectations. For now I'm tempted to keep driving until it gets worse.

Had to watch it again and afcourse subscribed because I am going tomorrow to check out two FA RX7 where one is apparently a parts car because of rust and the other was parked two years ago but has a cracked radiator and they removed the oil cooler and made apparently just a bypass. Frankly I think the cooling liquid frozen in winter and that's why the radiator went but this means that the engine is likely damaged also. But what I can't figure it out how the oil cooler cracked and that is a big concern. The problem is finding decent rx7 or part's in Europe so everything is sadly double expensive then in US, afcourse if you can find the part's. Great video and afcourse super explanation and I will definitely enjoy your Chanel.

I love your videos how you you pay attention to detail I started watching your videos because of it my son has a 1995 Mazda FD RX7 it has blown the rear seals on the rear rotor and we live in Chicago and there’s nowhere to take this car to get it fixed if you are willing to take this job I will trailer this car all the way down to you let me know.

Loved this video!! Great information!! Question: What about pulling a couple of 13B motors from the Pick-Ur-Part junkyards and taking the best irons and housings and the best eccentric shaft and both soft sealing and hard sealing them with new seals? I want to try rebuilding a 13B. I don't want to port nor turbo. I'd be happy with 130-150 horsepower and 110-140 ft. lbs. of torque and 60,000 miles of life.

Appreciate the vid

good shit man

Hey man, thanks for the info, no cookie needed. Good knowledge to have when shopping for a project car. I've been looking at either an RX8 for when my kids get older or an FC to do a 24 hours of lemons race with my friends. Great to know about used irons and porting. Where do you tend to find the best deals on used irons and housings?

Nice video

Good vid man 👍

Lot of great tips man. I didn't understand the relation between filled iron edges to match ports and triangle apex seals parts falling into bridges. If you care to say a few more words on that great, if it's a long explanation to write I have two more simple questions. Saw Rob Dahm building a rotary and when assembling he told not to compress the parts (irons and other sections) too much together because later when the parts gain some relief the seals might come off. That was prior the torque down of everything etc. It wasn't too logical to me because I expected from that point onwards that everything will just get tighter together not loosened at any point of the work. Maybe you know what he meant with that. Another thing I noticed is some aftermarket apex seals have stronger/bigger triangle bits to make them more resilient to fail. Is there any particular reason why Mazda didn't go by default with something like that but in a more extreme version. I mean, make the apex be a 2/3 + 1/3 part instead of this small chunk. I hope my questions are easy to understand. Keep up with the good work!

Love it

Brother that was one video you should have done long ago. Great video. Great detail of information. Was out of the rotary game for about 20 yrs but back in it. I wish I could buy you a drink of your choice and get you a cookie to spend time picking your brain. 👍🏻👍🏻

This is arguably the BEST run through of a Rotary Engine I have seen. You Sir are a champion. Can REW sequentials flow enough for a bridge or brappy port? I want to keep my car stock-ish looking and retain the twins but really want a brap. What smic would you recommend? Also coilovers that have brake line mounts (or what is the solution for those that don't?) I had hsd on my fc and zip tied them to the shock... A bit dodge...

YO GOOD FUCKING JOB I LEARNED SO MUCH I REALLY APPRECIATE THIS DEFINITELY SUBSCRIBED AND LOOKING AT ALL THE VIDEOS THAT GRAB MY INTEREST

Never clicked on a video so fast, thank you!!

There's the whole part about front and rear counterweights I need more help with . ..Also tricks and techniques about how to remove the important eccentric shaft bolts as well as it's removal. . . .. Let's not forget about oil metering pump. . .. .I need some videos showing me those parts before I tackle my own rebuild. . . ..I also need a video showing me how to get the crank angle sensor right along with the timing marks. . .How to land the rotors right when placing them back into the engine stackup. . This was a great video for me to understand some key things about what major parts to use and why. Thank you .. . 86 S4 N/A

Love this video! Got me pumped to rebuild my low compression Rx8. Had it since 2004. What’s the limiting factor on its motor from revving higher? Just rotor mass?

I just wish you lived in Oregon. Would love my own personal mechanic on these 😅 Sure, ideally I just need to learn it for myself.

Great info on all your videos. I’m going to build a unicorn…turboed 4 Rotor. I know enough to be dangerous about rotaries but have never worked on them. If you were going to go down this path what were be your dream engine? I haven’t decided. Thx!

It’s the best video I have seen how can I get in touch with you

I've never tried on a rotary but I know I've used "Comet" on piston engine rebuilds to help get the rings to seat during the initial start. It works like a charm on piston engines, I don't see why it wouldn't work on a rotary as well but I haven't done a rebuild on one yet. Pretty sure I'm going to have to shortly though. My son and I are doing a fb barn find rebuild right now. Keep up the great videos!

I’ve seen your videos and I’m very impressed and I have rx8 2005 shinka and sure that the coolant seals are shot , I’m thinking on doing this on my own any videos or tips will help . Thanks

Hi man how are you + it’s Dom from down under - I have a 84 12a motor and box - it’s leaking from the dowl pin front near dizzy - also I have a gearbox noise very bad when cold with the clutch is out - I have to start it always with clutch in till it’s warm - I’ve done the needle bearing and seal in the back of shale , I’m worry a little about doing the pull down and rebuild on my 12a , it’s runs so well drives well - I brought it about 16 years ago and have had in my dry garage till last year , it started first go - it my first rotor motor - I have the rotor bug now - I really would like to succeed with my car . My little glc coupe my first car - thx man dom

Hey, found your channel, and really enjoying your content! I'm currently eyeing up a 1984 FB with a 12A. It's in good shape, and I've been inside the engine bay and under the car, rust is reasonably minimal, and the oil is clean. However, it has been sitting for around 8 years. I'm prepared to do some work on it, but I'd like to know what to keep an eye out for, like rust on the housings or anything that might cause issues. I'm new to rotaries, and I'm excited to learn. Any advice?

Great Video alot of useful information. Have you done a. Peripheral port engine? Was wondering Apex seal type material and wear caraistics?

Hey man, greatly enjoyed watching your vid. I’m stationed in Japan and am getting ready to buy an Rx-7 FD. $30k+ these days man. My question is, what is the “ideal compression” that I should be looking for when buying one?

powerseal apex seals, OEM softseals, big turbo, e85 for that no knock life, haltech elite to keep the thing together and go skid it lol

My superchrged rotary did a 3 km hillclimb on 30 degree Celsius day with the water pump off! The temp dial was off the charts! That was 15 years ago! Still running same engine with no issues! Ceramic seals , viton o rings are good investment!

Have you looked into isometric finishing on side plates, housings, eccentric shaft etc. ?

I wish I wasn't here watching this, but it happened. I gotta rebuild

Great vídeo broth , una pregunta que los cojinetes se desgasten y el motor se bloqueado seria el peor escenario para el motor del rx8?

Hey I just bought a 04 and acts like wants to start and shoots flames out pipes but wont fully start. Tried pulling it as well. I did do a compression test but not with one made for these cars and best guess is front rotor has low compression while rear seems great. Motor sounds good turning over as well. Has brand new plugs need to upgrade coils and wires see if that helps which ones on it seems new just oem. Car came with coil overs exhaust cold air Intake and whatever else they upgraded. And is the 6 speed 6 port. If have to plan to pull motor and rebuild myself. Eventually plan to fully build it once learn alot on this type of motor first that is

I wish I knew more about rotary engines. You do not happen to live in California close by? lol, anyways, I parked it because of tire & wheel issues, so I am hoping the engine is still good. Going to watch some more videos.
