Very good information and well explained. Going to add one more, based on my experience. If you run a precsion turbo make sure you have an oil pressure regulator. My PTE has too much oil pressure going into the turbo, there for causing the smoke.
What about in my case my T2 smokes heavily on start up and once I start driving it it clears up and won’t smoke anymore once hot. The smoke is blueish so it is oil being burned but it completely goes away after being warmed up and doesn’t even smoke on decel. I just barely rebuilt the engine like a year ago which is kinda annoying but I did use the atkins viton o-rings and did reuse the trays instead of buying new ones.
I’m surprised you don’t premix in your RX-8. I was lead to believe that they didn’t oil enough from the factory to meet emissions regulations, which was the cause for the premature engine failures (compared to the earlier rotaries), is this not the case?
For a street car you're not really beating on them hard at all. Would see more carbon build up and stuck seals. Vs lack of lubrication failure. In a track oriented machine. Then yes. Premix away.
RX8 main failure is lack oil in chamber due to lack of oil ports trying to meet emissions ... You def should premix your RX8 it's literally the no 1 failure
@@RADPotential and premixing helps with carbon build-up , pre mix oil is made for 2 stroke engines that are notorious for piston carbon build-up, the oil helps keep that stuff low
got a 2006 rx8 its not my daily driving car but noticed when i start up after a day or two or a week later puff out a white bluish smoke from exhaust but goes away when warm do i need to rebuild the engine?
Mine was smoking under hevy acceleration olny till recently and now is smoking no matter what. I cant tell what the smoke is coming from cause i thought it was brake fluid but it is white with maybe a little grey but probably just white and it has no smell. Its a 12a engine in a 79 rx7. Do you know where i should start?
My fd smokes pretty good on start up but not at all during hott running or decel or anything like that. Just when it’s cold. It has a second hand single turbo on it which I think is the culprit
if your carburetor floods and you wait for it to unflood the gas will seep down the chambers into your engine and your car WILL smoke, and the SMOKE IS NOT BLACK. I can't stress this ENOUGH. The engine is NOT running rich after that initial start-up, it just has a bunch of residual oil and gas mixed together that burns for a good minute. So please make sure your carb doesn't leak at all before tripping balls.
Um the renesis has a restricted oil injector Pinole, I seen a video dude dissemble one... for sure they had too.. the epa’s grievances for the oil injected engines aka our love and the 2stroke dirt bike... so to pass emissions that’s why it’s equipped with the dual housing short oil injectors to run 2 drop lines vs the older single droplet and long vacuum drawl manifold atomizing injector...
I’ve got an rx8 with 54k on the engine. If it sits for many days it will get a huge puff of white smoke until it warms up. Can I get away with just doing a soft seal kit? I’m in East TN.
Hey I just picked up a 79 with the 12a and I was wondering what the premix ratio is for a fill up. I don’t plan on tracking it but I will probably rip on it
I just dump one of those baby 2.5oz fmx 2 stroke bottles with fuel stabilizer in a full tank of 93 running factory omp, 2 bucks on top of the tank when i fill up
I have a pretty unusual scenario pertaining to a 12a fc, I tried to watch some of your vids but I’m more confused now. Is there any way we could get in touch?
hi :3 i have quick question for you about 13b from rx8... Any chance you know why she doesnt want to start on cold but when you turn ignition 2-3 times it will starts straight away and on the hot engine starts without any problem. Did you see something similar and what was the problem.? :3
@@RADPotential could you avoid premix and the oil metering pump if you use carbon apex seals? You can still get carbon seals for 12a engines and I have a set I would like to use.
My 1984 RX7 destroys starters. I've replaced mine 4 times in 2 years (less than 5,000 miles). The engine is tuned and starts right away. I run the car weekly. Any ideas why the starters are dying???
Hey man, I 100000000% disagree with your thoughts on premix in an RX-8, here’s why- The oil injectors in an RX-8 are controlled by vacuum, and a lot of the times you will find that the oil injectors themselves have failed and do not hold vacuum anymore. I’ve worked on hundreds of RX-8s and seen this dozens of times on engines anywhere from 50k miles to upwards of 150k miles. Always always ALWAYS premix your rx8. I don’t care who says what. Not to mention, the OMP on the rx8 is electronic, that’s obvious, BUT what’s NOT obvious is that the OMP flows it’s max output at only 7700 rpm, and the map that controls the OMP stepper motor limits the stepper motor a TON in order to be more emissions friendly. So if you’re not going to premix, at the very LEAST change the stepper motor map on the omp and check your oil injectors religiously, or simply premix .5-1oz per gallon.

dude this channel gonna help a lot once i get my dream car thanks
Get it man!!!! You can do it!!
Totally agree with Eddy Hermansson,Thank you for sharing your excellent Rotary experience.Blessings!!
Super stoked on the channel I've been binge watching you guys. Also would love to see some more rx8 content. Keep it up man!
Rx8 is coming next week. Just wait until you see the sinkhole get fixed this week lol

It has a header and a 4 inch all the way back to a high power HKS muffler im thinking because of back pressure????
Right!! it shuts off sometimes on decell does some kind of back fire thing and shuts off but it starts right back up is it a back pressure problem???
2006 rx8 white bluish smoke at start but when its warm goes away whould that requires a rebuild or can it be something simple

Hey buddy question why does my rx8 sometimes while driving i let go of the gas in gear usually 4th gear it back fires and shuts off

My rx8 has the omp deleted. And is a premix only engine from the first start up. She has about 20k kilometers and is still strong.

Have you ever seen copper flake sludge buildup on spark plugs of rotary engines? If you have, what does that mean? Thanks for any input.
What does your coolant look like?
gotta remember some cars will smoke white with the sub zero starting fluid system
Yessir!! I have never been around around a car that has that system functioning
@@RADPotential mine does lol

Most likely a coolant seal, do you notice it using coolant?
@@RADPotential hard to tell. Very little. I just recently flushed it. The resevoir is down maybe 2 inches.
Thanks for the vid mate. 👍
Hey I just picked up a 79 with the 12a and I was wondering what the premix ratio is for a fill up. I don’t plan on tracking it but I will probably rip on it
I have a 79 as well I have the omp disconnected and am running a little more than one ounce per gallon.
I just dump one of those baby 2.5oz fmx 2 stroke bottles with fuel stabilizer in a full tank of 93 running factory omp, 2 bucks on top of the tank when i fill up
If you have an omp on it run no more than .5 oz per gallon even if your beating on it. . No OMP I wouldnt go more than 1 oz per gallon.
@@RADPotential whys that, i put a Lucas bottle per half tank, THE TINY bottle , i think that is 5 ounces

Check fuel system. Fuel pump is priming each time you turn the key.
@@RADPotential she was on "Mazda recall" for fuel pump ⛽
Do I need to check something als? :)
Whats the risk if you premix to much?
Gums up the seals and excess carbon buildup. Especially if you're not running the car super hard.
@@RADPotential could you avoid premix and the oil metering pump if you use carbon apex seals? You can still get carbon seals for 12a engines and I have a set I would like to use.
I have no experience with carbon seals. But I'd check with the manufacturer of them. I'd assume lubrication is still required

Bad ground? Or dirty/faulty connections and wiring
