- Have an RX-8 that’s been sitting for a while? Here’s how to bring it back from the dead.
I’ve gone through this too many times to count. Learned many hard lessons in the process and this method has consistently worked for me, and served me the best.
Best of luck to you!!
Tips I forgot to say in the video:
1) Start with a fresh battery!
After a year and a half, my battery was down to 5v. I bought a $20 charger off Amazon, pulled the battery out of the car and had it charging for about a week in my garage. Got it to 13.5v which was plenty to make it through all the cranking
2) Careful you don’t flood it!
If you’re impatient (been there) you’ll have too much oil and now fuel rolling around inside and your rotors will be a soggy mess. Then you’ll have to go to extreme measures to un-efff your efff-up. See Tip#5
3) How to know when to stop, BEFORE it floods...
Do this with the driver door open and put your nose to work... If you smell gas but the engine doesn’t sound like it’s even trying to start, you were impatient. Now gas is pouring out your exhaust and not lighting off because there’s too much oil still.
4) How do you know when to switch from no-fuel cranking to letting gas in?
Do it for at least 5 cycles (10-15 sec each) Before even thinking about letting gas in. Be nice to your starter. Let it rest in between.
Then try it with your foot off the gas. You should hear it try to start after 3-4 times(it will be very rough and ugly). Once you hear it trying, tap the gas a few times while you’re cranking until it’s able to rev to 5k or 6k. At that point, your work is done. Let off the gas and let it idle for at least 5-10min. Then do your happy dance. Don’t worry, your neighbors won’t see you though the cloud of smoke you just created. Once it’s clear, go for a victory drive.
5) I didn’t listen to you and it flooded :-(
No judgment. There’s a reason why I know this procedure by heart...
There are better tutorials on the internet (rx8club.com) but here are the basics:
Jack up your front driver side and remove that wheel; Remove all 4 spark plugs (pay attention where they came from, the plugs are different...); Pull the wire for the Eccentric Shaft Sensor (ESS) to ENSURE the engine won’t send fuel. Crank your engine many more times to let the mess pour out the spark plug holes. After you’re sure the gunk is gone, button everything up and start the process again. Have faith. You’ll get there
That's how I start my RX8 every time! Also a good tip if you live on a hill or just took a short drive or planning to store it for a long time when you park after you shut it off press the gas and crank the starter for one or two seconds this pushes all that dirty gas and exhaust out and leaves you with a clean combustion area. I only do this if the car wasn't fully warmed
Yeah every time I start mine I hold the gas down so it doesn't start for 2 to 3 seconds to build oil pressure even when it's warm it helps it to not flood and start up smooth
This video was a life saver, thank you!
I bought a Mazda rx-8 from an auction and it’s cranking but not running on completely. Will this work?
Looks like steam on the camera
It’s called a “ housing” genius
Did you have start up issues afterwards?
Did you
Not because of this… because I let it sit again. The Rx-8 intentionally injects oil into the rotor. The syringe basically makes up for lost time
@@mcohn16 if you know your about to let the car sit for a long period of time would a good idea be to do this and just let the oil sit in the engine so when you go to start it in the future it’s already there

I’ve never tried that, so I don’t know if that would work or not. I think the real answer is not to let it sit. Force yourself to turn it on and go for a quick drive every few weeks. That was hard for me because I had 2 kids in car seats and stuck to me like glue. Best of luck!
Never run synthetic oil on a rotary it won't last long..must be mineral oil
Really? Never heard that before. Is it because it’s designed to “consume” oil?
@@mcohn16 synthetic oils build up carbon deposits inside the engine
@@mcohn16 It's specified very clearly in the manual. Similarly, the starting procedure in case of flooding the engine is also there, and most people never see it. The trick is similar to what you specified, just keep the gas pedal depressed before you turn on the ignition (it cuts off the gas pump) and while you start the engine for up to about 10 seconds at a time (not to overheat the starter), then wait 30 seconds to let it cool before starting anew until you feel that letting go the gas pedal allows the engine to start. Like you said, it's not an exact science, but works everytime.
Not true though is it, Mineral oil nowadays is quite hard to find and more expensive, Every rotary person ive spoken to says Semi-Synthetic is perfectly fine, but you should never use Fully
@@mcohn16 first of all 5w20 oil is not a good oil to run on a rx8 you should run 10w40 and premix it whit 2 stroke oil in the tank 8oz for a full tank you will keep it alive for a long time whit those tricks
Any issues after?
That's what I was asking
@@rotarykilla26 well I ask too
Cool..I originally thought you were asking me since you replied to my question. Sorry
Sorry guys! Nope. You just have to let it run for a few minutes and let all the junk clear out. The rotary is actually designed to “consume” oil. There’s actually a little pump that injects a small bot of oil into the rotor as it spins. Because it sits, the seals dry out. So injecting oil in freshens it up so to speak.
Hope that made sense!
@@mcohn16 thank you and yes made perfect sense.
Why tf would anyone leave it that long? Stupid idea!
@@jakelamotta2387 This wasn’t my primary car. It supposed to be fun to have on the side, but stopped being worth it. So I sold it
@@mcohn16 I mean that's kind of the idea, is to not leave it sitting too long and to keep the engine cool.
I'm glad you sold it.
