Ok so I did the steam cleaning trick on my tii. It was very easy. After I was done i took the car out for a drive and felt like to boosted a little quicker. (probably just in my head. Also while doing it I found a few leaks where my turbo manifold attached to motor and DP attached to turbo. Didnt realize i had any leaks. Anyway for anyone wanting to do this (yes I know somepeople dont believe in doing this) it was very easy.

 

I do it every 3 oil changes. I use vacuum nipples that favor each rotor. I do one side then the other. While some water will still go to both sides, you'll favor one side which means even if one rotor wanted to shut down at all the other side would keep it going. I try to hold the engine at 2K rpm. It pulls less suction on the water and keeps the engine running. I typically do one gallon per side. It all takes about 5 minutes. The amount of steam out the back is quite impressive. A downside to this is that the mufflers and cat fill with water. it sits inside them. You'll continue getting steam out the exhaust for a while until this water is all gone. The car always runs better after doing this.

Do not try this on an RX-8. The engine can handle it but the ecu has no idea what is going on. Due to the readings on the O2 sensor, the ecu will dump extra fuel trying to compensate. Most of this ends up puddling in the cat where it gets lit off. The cat will literally glow orange and start to melt itself apart.

 

As anyone steam cleaned their engine and lost compression or bad things happen as a result?

 

ya mine seemed to respond very well since doing this. seems like a little more power. Which vaccum nipples do you use

 

I have heard of people that havent had much success doing this. Alot of people havnt had any problems. Mine runs just fine. The only wierd thing is after i do it there is beeping that comes from the dash. No warnig lights just beeping. Once i shut the car off and start it again it goes away

 

Mine is an S5 na so there is a capped one for each rotor on the lower manifold.

 

I was a little leary of doing it lol. but im glad i did now. just seems like my exhaust is louder now

 

I steam cleaned my TII a couple summers ago, drove it hard to make sure everything was cleared out, then parked it for an hour or so. When I tried to start it back up, an apex seal unseated and got stuck, locking my motor. Now, the motor was on its way out as it was, compression was like 80psi front and rear IIRC, but it's quite possible the treatment had something to do with it. Generally I think the water treatments are good though. I might do that today or tomorrow on the motor I built after that last one locked up.

 

as long as you do it in the right order you should be fine

 

How about a pick of the nipples you used. I want to do this to my S4 but I'm not sure which nipple to use.

 

Very interesting... Hope it goes well

 

Can I have a pic of the vacuum nipples and instructions to use for the steam cleansing trick?
My 88 vert motor has a lot of Engine Fog put in before layup last October, the steam trick should get the guck out,
Thanks,
Mike
