Do rotary engines actually eat apex seals like people say they do or is that a shitty misconception passed on by people who beat the shit out of their car and poorly maintain it?
I want to buy an FC and eventually bridgeport it for fun braps but don't want to be replacing nothing but apex seals all day every day. My old man and my mother both owned bridgeported RX4s that they DD'd and they never had this issue, but a pair of anecdotes are nothing to go off of. I don't mind wrenching but are apex seals seriously that big a deal?
It's a misconception passed on by people who DON'T beat the shit out of their car. A rotary engine needs to have the piss revved out of it so it doesn't build up carbon and cause those apex seals to wear and crack before they need to.
Even if they do need replacing rebuilding a rotary is a hell of a lot easier than rebuilding a piston engine. They're small, light enough that you don't need a huge hoist, and there's like seven moving parts total.
>bridgeported RX4s You best have photos of that shit nigger
Nathan Smith
Well that's interesting to know, I figured it was mostly from people who just sat there idle revving so they could spew fireballs out the back of their unit. Good to know I can have fun with it while keeping it healthy rather than having it be a garage queen.
I'll be seeing my old man tonight, he might have some photos from ye olde days. If this thread is still up I'll post em up here but no promises.
That RX4 was his greatest love besides his old Valiant Charger and Escort.
Jason Phillips
One of my friends had one and its partially true. They eat through gaskets faster then a conventional engine but its like a every ~10k service like everyone tries to make people think.
Carson Richardson
But its not like that is.
Hudson Butler
Had a quick look at my families normiebooks for you but I didn't find anything, did find this one of my uncle's RX3 though, he also had a pair of series 3 FB/SA RX7s himself but no photos sadly.
Well partially is better than 100% true, I don't mind servicing and replacing things so long as it isn't once a month!
Nolan White
There is a reason you see some old RX7's with original motors that have 150-200k miles on them, and it's the same reason you see them rebuilt with 70k on the odometer. The ones that last belonged to owners that took time to read the onwer and service manuals. An RX7 is NOT a honda accord and will do very poorly if you don't read the information the manufacturer provides you. They do not make good daily cars for people with a vague knowledge of cars. They need to be warmed up, rev'd out, and pampered, but they are absolutely a blast to drive.
Dylan Reed
Premix and you'll get 200k out of one easy. And, as another user said, they're loads easier to rebuild vs a piston engine.
Luke Ross
Lol @ all the people here that don't know what they are talking about and have never owned an RX-anything.
Luis Evans
have you?
Logan Collins
Understandable, if I can daily this car I'll do everything I can to take the best care of it, especially the premixing, as I have actually heard the FC's electronic oil metering wasn't as good as the older mechanical system.
Christian Roberts
It's an exaggerated issue that essentially doesn't exist anymore especially in this day and age. The advancement of metallurgy, tuning and better aftermarket solutions makes it entirely avoidable.
And for the record apex seals rarely end their lives in catastrophic failure, they just loose the ability to keep compression. Shattering only occurs with shitty tuning or turning the boost too far up.
Thomas Reyes
You can buy a system that does it for you, you just have to make sure the extra tank for the premix oil is always filled
this video is a meme, but basically fucking premix and keep your cooling system in order and you'll be fine.
Levi King
Well that doesn't sound like a big deal at all. Especially if I can just automate the premixing with an external tank.
Brody Bailey
From what i have read, NA rotaries are pretty reliable
Liam Hughes
Fucking noice.
Adam Richardson
I don't think you need to premix if your omp is in working order and its just a road car. Afterall, my FB RX7 has 120k miles and its never been premixed, the OMP does it for you
Landon Price
Umm. Timeout.
I believe FC's only had mechanical OMP's. FD's had electronic OMP's.
I own an FC (86) and an FD (94). I know this is certainly true on all my rotary engines (a 13B in the FC, a 13BREW in the FD, a space 13BREW for the FD, and a spare 13BT for a project)...
I premix on my FC and FD. Would suggest anyone else do the same. Use Idemitsu Rotary Premix Oil, if you can. Otherwise, use a TCW3 two-stroke marine oil.
And rev the piss out of it occasionally. Its a funny duality.. Any rotary powered car needs to be babied on the one hand, but on the other hand they need driven hard too.
Oh, and you can get a water/methonal injection kit and then you dont have to worry as much about carbon buildup. The steam from the water injection basically steam cleans the engine during operation.
John Flores
The later half of FCs (89-91) had the newly introduced electronic OMP which cut down oil movement to 25%, (not by 25%, to) this introduced the need to premix.
The only other car that desperately need to premix as well are the 04-11 RX8s because the RX8 got fucked over by emissions garbage.

Blake Nguyen
Look up my trip.
Christian Butler
No, you aren't a celebrity. And even if you did own a Rotary you're entire experience with them is probably nothing but an anecdote...If it wasn't you'd actually contribute to the conversation rather than waving around you dick because of your superiority complex. Now fuck off tripshit, stop farming (You)s.
Henry Jackson
lol ok kiddo You idiots can keep blowing up engines and feeding the meme machine Morons

Cooper Brooks
Might premix my rx8, I'm currently using a sohn adapter with external oil tank for the omp and I turned up the omp rate with cobb.
Still not sure how solid that setup is yet.
Adam Perry
So essentially, rather than that huge wall of text you could have just said "Premixing isn't necessary."? And good job on calling OP dumb, I'm sure he's just trying to learn coming from piston engines hence this whole thread in the first place. As an expert you should've been trying to help from the get go, where else is he actually supposed to take information from? I'm sure Google would literally take you to some stancefag blog that'd mirror this thread 100%.
Easton Myers
nah ur car is totally a two stroke and not a pos.
god speed dum dum

Juan Perry
Please then Mr. Expert, explain the OP's question in CLEAR WORDS.
Stop trying to use your trip and your "experience" to justify your shitty superiority complex
Please "enlighten" us instead of waving your proverbial dick around like an absolute cuck.
Thanks.
Juan Cooper
if rotards weren't turds they'd use them in airplanes, ships, boats, etc. where there are no emission regs.
wankel a shit. even your homo mazda admits it.
RX Dead.
Tyler Jackson
I wasnt here yesterday when the thread started. Otherwise this would have been way less retarded. Rx7club has all the resources you could want if youre not stupid.
Isaiah Thomas
I havent seen as much bullshit in one post
Care to explain why premixing is bad? Its the best thing you could do for any rotary Fuck off back to rx7club.com and keep spreading the "premix is a meme" bullshit linking to archived three post threads as your source
>my car is le two stoke its not 1993 anymore. accept it fake nostalgia fag.
Leo Butler
I never said its bad It just isnt necessary. Also rebuilds arent easy if you dont know what your doing. You wouldnt open a watch and say "thats easy to rebuild, its just cogs" Piston engines are just as easy. I bet you dont even know how to put in corner seals correctly
Dominic Robinson
Eat apex if no oil and they eat oil.
Isaiah Stewart
>if rotards weren't turds they'd use them in airplanes, ships, boats, etc. where there are no emission regs if you werent a retarded piece of pelican shit you would know they are still being used in all those things
You mad shit skin? Mad because the isreali defense force uses rotary powered uavs to bomb your goat farms?
>Rx7club has all the resources you could want if youre not stupid. And anyone there with half a brain recommends premixing
Alexander Rivera
>It just isnt necessary. It most certainly is if you want to reuse your housings come rebuild time!
>Piston engines are just as easy. An old ohv engine possibly.. get triggered
Dylan Stewart
git back over my border shitskin. rotarys aren't used by no major mfgs. >And anyone there with half a brain recommends premixing >rotard owners >forum users >not retarded kys
Michael Wood
Epic argument bro you sure proved me wrong
>huur why cant i buy a rotary engine powered kia rio rotaries are such shit lmao porofag cuck
Oliver Bell
>if i keep insisting, it has to be true!!! No >uses extreme example of piston engine Show how many seals are in a rotary
Andrew Hernandez
hillarious since I actually drive a Kia Rio. I also have zero pilot friends with rotary powered Sesnas. >back to the 1990s bud
Jayden White
Different user but some more modern i4s are fairly comprehensive and easy to figure out. Honda d series are pretty easy to work on.
Jayden Mitchell
>if i keep insisting, it has to be true!!! Right back at ya
Keep sticking to your contrarian belief but you are a fucking idiot Enjoy dirty oil that doesnt properly lubricate or burn off
Thomas Martinez
Anyone who isn't a halfbreed can rebuild an engine. A wankel is just shite.
If wankels were so simple, putin would use them. >checkmate libtards
Matthew Gutierrez
>changing your oil more than every 15k >20XX oh dear, I adjust my valves as often as you pull your lawnmower engine
Jacob Wright
>putin would use them lmao the KGB had 280hp rotary volgas
Lincoln Ross
What does librals have to do with this? V engines are a fucking pain to work on for the most part. Last one that i worked on that was comprehensive was made in 2004.
Jose Robinson
Since when is making an engine over complicated make it better?
Cooper Baker
>not owning I4 or I6s I blame your mother, not you. Its okay, you weren't raised right.
Connor Ross
>changing your oil more than every 15k Yeah pretty standard practice for performance engines
The dry sump corvettes need oil changes every 500 miles aircooled porsches need valve adjustments every 10k miles
Good to know the short bus can go so long between changes though
Landon Taylor
Reliability has gone down the toilet since the 80's
Lucas Bell
Own an i4 civic. Owned an i6 trailblazer before that(fuck the electronic on it). Havent touched rotary my self but rx8s are fucking everywhere in nc.
Nicholas Morris
>lmao the KGB had 280hp rotary volgas sure ... rotarys that usually didn't make it past the first oil change and had a maximum life of 20,000km
Gavin Jenkins
Didn't Mazdas rotary get banned from Le mans 24hrs. Too reliable and too quick from what i recall. Something to do with being able to go entire seasons without a rebuild.
Yes. I beleive it's just the 89-91 OMPs that are problematic. The earlier mechanic ones, and the FDs OMP, should both be fine and not need premix.
John Rogers
The problem is that whilst rotaries are awesome for race applications in terms of performance and reliability, not much of that transfers to road use. I think they were banned because of that. There are stories of the cars from le mans rolling into the pits and idling as normal after a race where all other cars would struggle to maintain any semblance of idle. Judging by that the piston engines probably lost a ton of power over the race where the rotary wouldn't.
Kevin Martin
They're a fun weekend car but DDing a bridgeport is just moronic, they swallow fuel like its going out of fashion and your neighbours will want to murder you in less than a week. Oh and you'll stink like fuel everywhere you go.
Xavier Campbell
>Everyone is dumb besides me! >No, i wont give actual advice, because you'd all be >too dumb!!!! >to understand >these idiots amirite ACTUAL rotary owners such as myself?? >Imagine that, someone wanting to buy a car that i own too >AND ASKING ABOUT IT!!! >how fukkin dumb do u have to be right???? >please give me attention i have a trip
Brayden Taylor
Most dirtbikes need new pistons and rings before rotary owners consider an oil change. Four stroke dirtbikes.
Most motorcycles in general need several valve adjustments, chains, sprockets, and a bearing here and there before a rotary needs apex seals
Now tell me why people complain about rotaries
>hurrr how can I DD it 200k miles a year?
Colton Perry
same year model evos and wrxs have seen more engine (and gearbox) rebuilds than fds its just a meme but one some people take too seriously
Easton Collins
>Too reliable They wont ban over that, if they did nsx (the old one) would be removed. Idle is one reason i know of.
Gabriel Powell
Same as 7m supras exploding but all you have to do is get a new gasket to prevent it
Levi Nguyen
Honestly premix or sulfure coat apexs would probably make the rotary looked at as more reliable. Though rx8 eats oil faster than older rx7s from my experience talking over with rotary guys I know. Most normies buy rx8s because they were trashed by the first owner, likely to be trashed by the second, and eat oil faster than most oher rotaries meaning unless they are premixed and maintained for premix there is no hope for the engine. Fd and fc have fine gearboxes and body though normies think rx8 these days because cheap. Rx8 has fixable issues that are like hiw honda auto trabs are fixable in its issues, cheap to set up so there is no problems or less problems though >Normies >Auto knowledge >Fixing anything themselves >Thinking regular mechanics understand/can fix specialty engines
Xavier Perez
Isn't that the same with fieros, mr2, older si/sir/type s hondas, and last two gens of firebirds?
