I bought all the stuff to do the atf trick on my fc, I was originally planning on doing it the plug way, removing the lower plugs ect...

but I heard about a way that FD's do the atf and I was told that this way would work on FC's. I was told that on a FD you can connect a funnel or hose to the boost nipple and fill that with atf while the car is running. Is there a way to do this on a NA?

My friend Heath on the forum told me about this, he heard of it from someone that works at K2RD and he has done it on his car.

anyone know about this way?

I read in tech support that water can be used, instead of ATF, while the car is running.

 

The whole goal of the ATF is for it to sit for a while and dissolve carbon deposits.. It's not going to sit for a while if your car is running.. ATF also will de-flood a car, but if your car is running when you do it, you don't need it to be deflooded..

You use the water while the car is running, the atf while it is sitting. IF you have an 86-8 NA there is a vacuum hose on top of the manifold you can use for both(let the runnign engine suck in water through the hose, or pump atf into the hose when siting). IF you have an 89-91 you can use other vacuum lines, but theyre not as direct, meaning that if you use atf, it could take a longer time to get it all out of the engine once you restart it.

......water?

 

...I read a little on this the other day, but always wanting to know more. It works basically the same, doesnt it? except it uses steam to clear the carbon deposits, more efficent and cleaner burning than ATF i suppose. Could any one explain a bit more, has anyone done this much?

 

Do you think the water trick actually works better than the ATF??

For some reason I think that the ATF would work better...

 

water helps break up carbon b/c as you know liquids are not compressible so the compression ratio increases and breaks up the carbon, and also steam cleans the combustion chamber

this is what my old shop teacher told me and hes done that for years w/ cars. i guess it works the same on rotories

 

The only thing that I would worry about when using water is that the carbon might come off in chunks and cause some internal damage. The atf works by disolving the carbon thereby lessening the chance of this. It takes a little bit longer but for the less chance of engine damage, I would not do it any other way.
Just my 2 cents.

 

ATF is poor at desolving carbon depostits, it just gives a flooded engine enough compression to start. To remove "all" the carbon deposits from your engine, try a mix of kerosean and diesel fuel. Let it sit in there fr a good 5 days......(caution, lotsa smoke on start up! but NO MORE CARBON)

 

if you run a water injection system all the time then there would be no carbon to build up, plus better boost

 

Alright Who's got water injection. I asked this a while back and everybody threw down with it but no one actually came down and said they used it. I know that it removes carbon , but i don't have a carb to pour it down into, only expensive electronic thingies. so i guess i'll stick to the ATF. I've also heard the same thing about Kerosene and diesel from the BUG guys but it's really small amounts. What small is don't ask me, ask them.

 

Ok, I have done the ATF thing a few times on my 3 RX-7's, but I really dont see how it works?

I got a 12A completely apart and poured ATF on it (rotors) and let it sit for a week, it dont make no difference on anything coming off it. Only way I could get the **** off the rotors was a kerosene and parts cleaner. Like brake cleaner or carb cleaner or paint thinner...And a brush and a LOT OF WORK!

Now when you got one thats carbon locked, it kicks ***. Give it just enough compression to fire up and then break the apex loose...

But as far as cleaning it? I dont see how?

 

heh, I'm bringing this one back from the dead, I ran the atf through a vaccume hose, it was really easy took like a minute. I've thought about the water treatment too, I'm gonna do that another time. I wanted to do the atf this way instead of through the lower plug openings because It would assure me that the atf went everywhere.


I'll post some smoke pictures tomorrow
