i was reading the thread on the carbon builup and read that there was a way of inserting WATER into the intake manifold and this would cause the carbon builup on the apex seals to come off.is this true because it sounds scary.my engine runs awesome but i have never tryed this. THIS IS WHAT WAS POSTED ON AN ERLIER THREAD.

"Water instead of ATF for decarboning
Hey y'all, I was talking to Rob Golden at Pineapple Racing last weekend and asked about his experience with the ATF treatment. He said that he prefers to use water.
1) works well, steam is very effective at breaking up carbon. Gives a noticable power gain.
2) easier and quicker, just pull a vaccuum hose at the dynamic chamber and pour 2 liters of water in (no kidding) while the car is reved up and down above 4k rpm. Just pour it in as fast as you can without killing the motor.
3) doesn't fowl plugs, O2 sensor, or clog the cats like ATF (actually cleans them).

I gave this a try last weekend and here was my experience:

I pulled a vacuum hose off of the dynamic chamber and placed a fresh hose in it and submerbed that
hose in 1 liter of water. The motor sucked up the water over about 3 minutes or so. I had to give the car gas to keep it running; about 4 k rpm most of the time, but I varied this quite a bit between 2k and 6k rpm. Obviously the car ran rough during the treatment. Towards the end of the treatment I noticed smoke coming from the side of my car near the back wheels and a burning smell. I looked under the car and to my suprise the cat and muffler pipes were glowing orange hot! (it was about 30 minutes before dark) I don't know wtf was going on but it got my adrenaline going! I shut the car off and let things cool down.

After things cooled down I took it for a spin. The car runs better, idles better, and has a bit more power (feels like 10-15 horsies, but this us just a guess). It also has noticeably better response at part-throttle. Feels more torque-y.

It's the same principal for all cars: get water into the intake manifold. With most 1st gens you can just pour it into the carborator"

has anybody done this and how did it go.
please let me know because i was thinking of trying this to clean up the seals...

IS THIS 100% SAFE!!!!

its safe
pour slowly tho, you dont want to kill it, its a beaoch to get started again with water on the plugs

Dont pour water into your intake, you could liquid lock it. A fine mist, like from a garden sprayer is better. Also, youll need someone to press the gas to keep it running as the water is sprayed in.

peccas

should i spray it in the intake or straight in the carb?
have you done this????????

how much water???tap or distilled???

thankxxxx..

BigJim

how do i do that on Fuel injection. I was thinking of doing the powerfoam treatment by taking one of the hoses off my ait intake and spraying in there.

Rx7carl

Never on a rotary, never needed to. I have on a piston engine before. Just removed the air filter and sprayed it into the carb. Would be the TB on an EFI car.

i set the idle to about 2500 and slowly pour it into teh secondaries, with the butterflies closed, they keep too much from getting by too fast

Wankelguy

Agreed, except those of us with two hands can probably work the throttle linkage by hand while we're spraying the agua down the carb with the other.
