Whats the best way to clean the interior rotor housing
I was wondering if the best way to clean out carbon in the rotor housing is to use transmission fluid. I've heard of people using engine degreaser and other stuff.
I wanted to know if it is safe.
And Also do you pour it in one plug hole at a time while the other 3 are still in, then crank the fluid out, then put the plug back in, remove another plug and do the same until your done. Or exactly what are the steps .

Its better to do it with the engine out and then squirt a lil ATF in the exhaust ports and on the apex seals then you can just turn it around by hand and work it in, Ive heard of people doing this and getting all the build up off aroung the apex seals and make them allot more springy and bring back better compression

based on this respones what is the turning point in RPM's between building up carbon and clearing it out? This is not a smart *** response it is as serious question.

I have heard of people putting auto tranny fluid into the rotor housings to clean them up. I have seen this done with a 13b in an '85gsl-se. i dont know if youd get the same results with the FD or not. But what we did was just cranked the motor around by hand and poured a little auto-trans fluid into each chamber on both rotors and let it sit over night. we bought 2 sets of new plugs cause you are going to foul out at least one set. the next morning we called the fire department and base security to let them know we were gunna be making alot of smoke, then we let it rip, it blew a *** load of white smoke for a bit. Once it was done doing so we changed out the plugs and the motor felt like it had new life in it. once again not sure if this is a good idea in the FD or not.

I have done this to my fd twice now. The engine is stock with 39,000 miles. It won't hurt a thing. The easiest way I have found is to use the vacuum nipple on the upper intake manifold where you would plug in a boost gauge. I use a very small funnel and a piece of silicon hose. Attach the funnel to the hose and the hose to the nipple. Start the car and pour in the atf. The car will begin to run rough. After the engine has ingested a few ounces turn the car off. It helps if you have someone do this for you while you are pouring the atf.
Allow the car to sit over night and then start her up (Some people say the atf may foul your plugs but I have never had a problem. If you are concerned you can always remove the plugs and turn the engine over a few times to blow out the excess atf.) After the smoke dies down enough take it for a drive, gradually running it harder and harder. You certainly want to end up with a few redlines.
That's what Dave from KD rotary advised me to do. I have heard of others using a bottle of water with one end of the hose in the bottle and the other attached to the upper intake nipple. Allow the car to ingest some water while having a friend hold the throttle around 3,000-4,500 rpm's. Go ahead and aloow it to suck down a liter or so. At least I would. It should literally steam clean the inside of the engine.
Best of luck!

this last one is a good one me thinks

it talks about things that i didn't think about like cats/side seals.
i have used atf on a fresh rebuild but i try to avoid it.
it's ur call what u do. I dont' think there is definitve proof either way.
