Based on this, I wonder about 2 things. One is this will help remove ehaust port build up of just housing/rotor build up? Two is how safe it is to do this with a turbo fitted. Assuming you are lucky and any carbon "pieces" pass straight into the exhaust path, whats likely to happen to the turbo?

Ohh and nice DIY! We cant get seafoam over here so I think (depending on answers here) I am going to order the mazda stuff.

it starts at the intake port, when u crank it the vacuum it create will suck the cleaner in and stick around whole rotor housing.

it shouldnt effect a turbo cuz none of the cleaners will get into your turbo.

the cleaner will make the carbon like *mooshy liquid* and when u start it, everything gonna burn together(the cleaner itself is flammable) and push outa the exhaust port.

 

so my cars got around 90k and Im a new owner of it. I have no idea if this was done ever. I realize that it needs doing I'm just worried about what chickenwafer said above.. dont want my engine to pop this weekend, or ever for that matter.

 

Well, what u can do is , start slow by using good Fuel System cleaner like RedLine SI-1 for 1-2 tanks of gas. then u do the Mazda Zoom Zoom Cleaner manually.

 

Just got done doing my Engine cleaning....I am @ 83k. Feels like my rotary is back into action. Thanks for everybody for letting me know that mazda has this product.

Zoom...Zoom!

 

OK so My 8 has 75,000 and I have a feeling that this was never done to it. My 8 is down right now cause I'm changing the ignition coils, plugs, and wires because I was having some power loss problems. I'm still waiting for my wires to get here from mazdatrix which wont be til wed or thurs. Do you guys think I could do this cleaning and then let it sit until I can get everything put back together or should I just wait and do it once I get the ignition system back up and running. I didn't know if the cleaner would dry up or cause damage to the engine by sitting in it for a day or so. Thanks for your help!

 

i did thi yesterday and i ws expeting a ton of smoke.... i let it soak 4 two hours.. it only smokes on the start up.. and it hesitated to start but as soon as it stabalized after like 5 seconds i reved it to 6.5K rpm 20 times...

It smelled Like burnt plastic IT WAS SOO FUNKY EWWW but no smoke..

the car had 46K miles and i always use the cleaner int he tank and other engine cleaners but i tried the mazda one and not so much smoke it just smelled bad for a little bit..

I did notice that the engine revved smoother and my intake makes this whistling noise and now it seems its whistling is a little louder but not much.. maybe its just in my head

 

Ignore my PM nycgps great DIY

What happens if you dont unplug the E Shaft sensor?

I have always just gotten a cup of Sea Foam, let the car idel and run a vaccuum line with a T splitter to the 2 nipples and let it gradually suck it up.

 

if u dont, the car acts like normal, meaning Fuel will be injected into your engine. not good.

These stuff will melt the carbon down and turn it into "black-ish" liquid thats flammable. So when u start ur engine, it will burn it off.

 

hey ive heard on RX7 they just put seafoam in the gas tank. like just put a little of it in.. would that be ok in the RX8?

Few people here have done it that way. I believe its good for the smaller issues like sticky apex seals but not the large buildup in the exhaust ports. But thats just my understanding.

 

Some people actually use Water for decarb, its cheap and easily to find (freaking tap water will do). but it will decrease the life of the CAT significantly.

 

alright im going to try that. do you know how much i should put in? and should i do it with a full tank of gas or what?

 

Pure curiosity...why would water decrease cat life? I would have thought of all the options water would be the most cat friendly.

Not 100% sure...in fact I have nfi. Do a search for sea foam and you will find a few references.

Good write up. I did this last night (first time, at 51k miles) and the tip about removing the airbox and washer fluid reservoir saved me some frustration. I didn't even have to crawl under the car. One thing I would add: watch your hands unplugging the e-shaft sensor when your engine is hot! A set of long, curved needle-nose pliers worked well for me. I was able to inject Seafoam using a 2oz syringe and two feet of vacuum hose. The whole process took less than half an hour, not including soaking and start-up, and the difference is amazing.

 

Noob question. instead of using the back nipple, can you use the the vacuum line coming off the top of that intake? I believe its going to the brake system? Thanks

 

Thanks for taking time to make this DIY nycgps, I need to do this soon.

 

if u want to kill your system. then yes. You could.

 

what is wrong with that idea? I know of at least 3 or 4 including my own that have always used this method and had no issues....?

 

ok so I just did this to my car. I poured in 2 oz's of seafoam into a bottle attached a vacuum hose to the first nipple and put it in the cup cranked the engine for 10 seconds. the did the rear port. let it sit for an hour. on the second port the engine was shaking violently when cranking no idea why.

while waiting I connected everything back together and played some COD4on live.

I came outside started the car took a while to get going and HOLY F^%$.. My neighbors came out thinking I set a tree on fire. My whole street was covered in a plume of smoke . i got a little scared.

so i revved it after the warm up and majority of smoke had dissipated. then I revved it to the 6k 20 times still a bit coming out put some oil in my vacuum line for port 1.

and wow I have to re learn the car it has at least 5 to 10 more hp. keep in mind this car has 101,401. on the clock I'm gonna do it again in 3 weeks. FYI get a Mask so that you don't get a migraine for 10 hours like me after inhaling all that smoke.

P.S. this is a simple DIY if you have any wrenching under your belt.
P.S.S. didn't need a second person just a long enough vacuum line to reach the cup which was supported by the air pump and passenger side strut mount.

 

I haven't been ableto find any really good videos of this being done to an 8 so I made my own. https://www.rx8club.com/showthread.p...22#post2622122 Tht captured the camera dies at 1:15 but It captures the HUGE cloud of smoke! The car is running muche smoother.

 

U dont really need a 2nd person, but It will be A LOT easier if u have one. You dont even need that person for more than like 10 minutes anyway.

Oh yes, the smoke is pretty bad. I walked away when I do that and it was pretty windy that day so it all blew away in couple of minutes.

 

If i have an AT would i just hold the accelerator while cranking and call it a day???
