so there is no agreeement on whether this is a safe or unsafe proceduure and whether it does help or doesnt?


thats very informative

 

I'd say its safe, based on the fact that everyone I have ever talked to about it (thats a lot, actually) never complained about it.

However, never heard anyone doing it to a rotary.

 

I'm going to give it a try tom on my 12a, i've got a swap coming up anyway so nothing to lose.

I re-read the thread, so which of the six times that was said it helps didnt you see? And safe or unsafe, that was answered at least 4 times. Just dont over do it, a bit o common sense must be applied. I will say it is safe and it does help.

 

i definately see tehre are more poeple that says it does more good than harm

teh confusion comes from the one post that says he dumps nearly a 1.2 gallon threough and another that says he just uses a plan mister to get the waater in.

the couple posters that say its risky and not worth that risk are so certain in their opinion that its bad i am reminded of the dino oil vs synthetic oil in a rotary debate.


youre right lots of people have had good results, im just not sure how much water or how fast..

like as far as vacuum lines go can i use the idle compensator line to feel water?

 

There is a professional cleaner called 44K made my a company called BG.

It is designed to clean out carb and it works wonders. That and a bottle of water would work well.

 

I did this last night, i just used one of the vacumme lines from the intake mani, and went through about 1 liter in about 5-10 min, I think it worked pretty well, does idle better, and does feel a bit faster, I can break the tires loose a bit easier also, i recommend it.

 

wouldn't the carbon that's breakin loosse clog the cats?

 

Look at your cat when you do this, you could light a cig off of it, it gets hot, carbon not an issue. As far as how fast (cptlou) pour it in right until the car dies, youll know, it does recover itself quite fast, youll need to rev to about 4000k to, I just grabbed the throttle cable whe I do it.

 

And so my other question would be, how often should it be done?

 

Dont know an exact schedule, but you could probably do everyday if you wanted. Carbon buildup is different for everyone. The more you baby your car the more carbon buildup, I hit 7k at least once a day.

 

me too, so I guess I wouldn't need it that often.

 

Do a search for Amsoil Power Foam for another (safer) option.
But if you're dead set on using water, by all means use a spray bottle.
BTW, this works on Fords as well as Chevys.

 

It works on all cars and jet engines too. Ooooh, not an electrical one!

 

I just did it on Rosie, WOW! I was worried because my engine had been sputtering, and this fixed it. LOL 16 oz of water fixed the problem.

 

Water injection? Never thought it would work on a rotary. I might try it...but not first. MMO=Marvel Mystery Oil

 

For the price of 44k it better do something.
I've put in my gas before on my nissan sentra, never noticed anything, I've heard it works well though.

 

Why not?

 

I don't understand why water would be anywhere near a good a cleaner as ATF, MMO, or powerfoam. For a rotary, anyways. Old school v8s ran pretty hot. Our rotaries run just barely above water's boiling point. Doesn't seem like it'd produce much steam if the water is only in contact with this level of heat for under a second. I suppose if some water pooled up in the bottom and produced steam, then maybe, but if water is pooled up down there, you have bigger problems. Further, the water will actually cool the engine down and be even less effective as a cleaner. Seems like it was a good idea in the 50s-60s, AND with V8s, but now we got stuff like powerfoam. I'm going to go out on a limb and say that any increase in power/driveability issues are either a placebo, or your plugs are cleaned and produce better drivability. You can't expect 15 years of carbon buildup to go away just by dumping some water down your intake. Hell, it takes overnight soaking in degreasers and serious scraping to get that stuff off to any signifigant degree.
Not to sound over-negative, but I just think it's a bad idea.

 

ill give it a try, just going to make sure its distilled water, i prolly do it this saturday when our 3 car garage should be close to done, i dont know if im going to add alittle oil first then put the water in. i find out when i get there

 

I think you may want to re evaluate the actual temps of a rotary. They are extremely high verses a boinger. It is extremely important to keep oil and coolant in a rotary because of the temp. The chambers never fully release all the thermal energy they store therefore making thermal dynamics of the engines a major concern. Steam is an excellent carbon remover, been going on for hundreds of years. And yes steam will remove a lot of carbon thats been built of for 15 years. Crawl off the limb, the increase is because the springs under the seals are able to do there job better for lack of carbon. Not to sound over positive but its a good idea.

 

 

I suppose it depends on where he is measuring temperature as he wasn't very specific.
The water temp on a rotary engine is usually lower than on a piston engine, but the combustion and exhaust temps are much higher.

 

Please explain this one, if your refering to the thermostat then yes because any hotter and the aluminum housings against the steel plates will warp like a ****.

 

you guys are serious, right?


INtentionally try to hydro-lock an engine.


Just use MMO, and rev the **** out of it, LIKE IT SHOULD BE, and your engine will be crystyal clean. I'm not sure about this whole add water thing... In my previous experiences... water = teh devil.
