Anyone used water to clean carbon vs. seafoam/zoom?

Water works, its just that you have to be careful with it.
Some people crank the rpm to around 3 K while injecting water into the combustion chambers. It works really well.
Its just that this method might kill your CAT. Since Water can carry a LOT of heat so the Steam might kill your cat on the spot.

Really?
Water works. Never tried it on a 13b.
Don't follow the TSB using seamfoam or some other method.
You need to disconnect the cat before you do this procedure.
All that crap you pore down the engine goes into the cat.
Don't believe me. Search and you will fine Ulloose has posted how much comes out the exhaust pipe.
Either method destroys the life of the cat unless yo disconnect it.
Ja sure MM has done this several times and I believe he does not remove the cat.
Maybe he can chime in hear and confirm this.
Then we will know for sure how much the cleaning method effects the cat.

I use a method of a mix of one liter of water and four oz of WD-40. I disconnect the caps on the intake manifold(next to the windshield washer fluid bottle) and run a vacuum line from the manifold to the bottle and hold a 3k RPM rev and let it suck up the mix. I do this after long trip where I use my cruise control most of the time. It works great. Engine idles smooth and never had one problem with it.

Okay... if you say so.
You can't get enough water in a rotary to hydrolock it... is that better??? It will still move, and rotate...
Unlike a piston motor, which will get to the point where you can not continue the pistons upwards movement because the water is compressed to the point where it changes the viscosity. And you will not be able to open a intake or exhaust valve to release it. That is Hydro locked.
and it is a myth that should be covered in your high school physics class that water is not compressible.
Check this out...
The water that is at the bottom of the ocean is compressed by the weight of the water at the top, therefore the water near the ocean floor is denser than the water at the surface.
But here is some real science:
If you compressed water in some type of laboratory setting using a metallic sphere made of copper which was heated to extreme temperature to expand then dumped into a pool of water, the gap left open to fill the sphere with water would close over from the coolness of being dropped into a liquid cooler than the solid which would lead to the sphere shrinking and the water inside becoming compressed.
Whew.
So as water is compressed, density increases. The property is known as "bulk modulus". Water is compressible, but being a liquid it is nearly incompressible (which is where your statement comes from I guess). The amount it can be compressed is defined by the bulk modulus.
See this hyperphysics link: http://hyperphysics.phy-astr.gsu.edu/hbase/permot3.html

As interesting as that was, your still wrong, 10:1 compression of water in a renesis without breaking anything? Have you any idea of the kind of forces that would require?
There are rotary pumps, yes, but I think you'll find that the ones for liquids have an outlet where you have some spark plugs...

All this talk of compressibility... but when I read these decarb threads I wonder about the effect of running an engine with solvents flushing through. Don't the solvents wash away the oil film? Will the seals wind up scuffing?

When I seafoam, I run a Lil' bit of 2 cycle oil through the intake manifold ports to lubricate before start up. The WD-40/water mix works real well for me

well water doesn't seem to bother my car too much, went through bout 2 feet of water and it went in my intake AEM cai hit my MAF with a lotta water picture a straw sucking up water. instantly shuts off steam from my headers and exhaust, i freak out, towed get home, clean it up wipe off the MAF sensor(not a lot of water but enough around it to make no air flow readings possible.) , little zoom zoom cleaner in the nipples, sounded like it was flooded when it started up, like REAL bad flooded so i just let her sit for 20 min giving it a little rev here and there. later BOOOOOM. jk seems to be fine, as if she was flooded my guess is MAF told it to dump fuel in cause i counldn't read the G's so it flooded it self and a lil water might of gone past the throttlebody but i did feel any moisture. but wouldn't recommend driving through water, no signs posted bout flooding (fyi not like im driving through a river.)

Ken-- I too wonder about oil film. The mazda TSB instructs the shop to increase the mop output while doing the decarb procedure. I dont do seafoam and I dont do the mazda cleaner since I cant increase mop output at home.
I just click on my w/m system and driver the heck out of it.
I have ran a gallon of water in it over a 6 mile distance. NP.

Interesting.....I've never heard of anyone using water ever in an engine generally speaking to clean it down while running. I would of thought it would dilute the gas and result in no spark or a relatively weak one.
I wish pics could be provided to show a tear down after someone did this to see how much it really cleaned the engine up.

I wonder if it would be beneficial to use the water method first, followed by a SeaFoam soak. Get rid of the bulk Carbon so the SeaFoam has a better shot at the nooks and crannies?
