i just did this, put about 2 liters of water into it. runs the same as it did before. i felt bad for the motor though since it was shaking like i was giving it electro shock therapy.

It has also been said (By many people before...) that this "trick" won't help EVERYONE's idle situation... It helps clean out some carbon build up yes, but if you have been redlining your car around everywhere then chances are you have less buildup then someone who drives it never taking it above 4k.

Also, maybe just doing it once wont help you out.... People do it on a somewhat regular basis, once every two months, etc... a maintance habbit. So just once is not 100% garantee to help you out...

I try it today and it work pretty good I think. Idle is smoother and seem like its running better. Thank you for this post. It is good info.

I did this on my suzuki samurai (soon to be rotary powered ). Idles better and starts nice and easy. I noticed lots of blue smoke, then lots of steam. My sparks were nice and clean after that. Seemed to work well for me. My weber carb is not tuned very well though..

Just a word of advise, I did the water trick and have done the ATF. I found the water to work well, i'm kinda scared of ATF cause people have had problems with it eating at some internal seals if they were in bad shape. So I say if you think you might have a bad water seal don't do atf or you might start to burn coolant. Also check your oil afterword you might need a change after using water or anything for that mater, although water may be the worst because once your engine turns off it will condesate and start to rust internals i sugest running the car a while after useing water and then an oil change. Also checkout amsoil power foam its a product made for cleaning combustion chambers.

I let a motor sit in a whole lot of ATF for a full year, all the internal seals were in fine shape.

Just letting you all know......

yo, haow can water condense if its already been burned/boiled off? as long as you dont pour a bucket down the TB after you turn it off, corosion wont be an issue.

So does anyone know what the best vac hose to use for this? I want to do this, but want to get a vac hose that will feed both rotors.

yes someone please let us know which vac line to use that will get both rotors evenly. i will do this as soon as someone fills us in. i think i have some carbon buildup in my motor cause its a jspec and there's no telling how long it sat.

I already told you...

there are three vac lines behing the TB near the firewall, So I could anyone but the middle one?

OK I finally took a picture of it today, this is the vac line I used.... again.. I am NOT sure if it's the ideal one to use. My guess is that it feeds both rotors since it's very high up the intake track.


good luck!

i only see 2 in the pick, arent there supposed to be 3? i havent looked at my car yet but it looks in the picture like there is another nipple under the line you used making it the middle one (not to be used) am i right?

elfking

On my 88 Turbo II that middle line is the vacuum line which is run to the Spider for the oil metering system... wouldn't it be very bad to disconnect this line? Even for a short amount of time to run water down it...

cprx7

my car never had a third line since I bought it.. maybe it's the cruise control vac line.. I am not sure.. since my cruise control was non-operational also. The middle line is the vac.. when I unpluged it all the car did was idle a little bit higher. I don't know on the TII. Nothing bad happened to my car.. that's all I can say.

I said the front of the UIM, not the rear. Look behind the alternator.

Mint87RX7

somebody get a pic of exact vac line and post soon, i want to clean my engine

I looked and I only saw one in the front of intake manifold and it only lead to one intake runner on the front rotor.


Can someone please get a pic.

nestorx7

i did it today in my na s4 ! i did it in the lower vac hose in the back of the dynamic chamber ! it did not smoke a lot but it's very smooth now and i only used about 3 16oz cups of water !

Hydrolocking is something that happens to piston engines. I guess it could theoretically happen to a rotary engine, but it is not something that you will ever see.
