I'm not sure if you're asking for advice or what... but I'll chip in.

The glowing exhaust is not from the 'steam cleaning' - chances are it's been doing that all along but you never noticed it. Unless you park over grass or dry leaves, this shouldn't be a problem. There have been several threads about glowing cats; you should dig them up and read some. I say that because different folks have had different causes/fixes. Good luck.

 

When your feeding your car water, you need to press a lot of gas to keep the car from dying. When I did mine I was boosting 7+psi as I was injecting water. This and the combined stress added by the car trying to combust water adds a lot of stress to the motor and prob is why ur egt's skyrocketed.

 

Kind of a side note, but im really suprised you had to press the accelerator that much to do this steam cleaning. When I did it a few months back I just had to hold it at about 3k, still in vac. What size vacuum line were you using? Is this what other people have experienced?

 

7 psi in neutral? Were you using your anti-lag setup?

 

No. My cousin was behind the wheel as pressing gas and when I was feeding water, or too much water he was almost flooring it to keep it alive. I then learned to feed alittle water at a time but after when I checked the pfc, it hit around 7 psi lol.

 

How are you feeding it water?

 

I would like to know this as well /\


your supposed to take a vacuum line, place it on the UIM nipple (one rotor at a time) and place it into a gallon of water or so and let the engine suck it up....you don't feed the water anywhere.


BTW, I was able to do the steam clean process by myself with no other people around and it went perfectly.

 

what did the commander show? max boost for a stock twin car in neutral is like 3-4 psi IIRC.

There's no way you you can 'feed too much water,' the engine sucks it in based on throttle position. Your cousin did you no favors by flooring the accelerator pedal......you can feather it and keep it at 3k with no problems.

 

I fed water through the nipples on the uim. I dont remember what the PFC said exactly but I think it was around .35-.4

What I mean when I saw "feed too much water" is how long i let the car vaccum water continuously. What I started to do was just let the car vaccum water for ~5 sec, then wait a few seconds then do the same. This was the car didn't build any boost in neutral and work hard to stay idling.

 

good thing i found this thread. i was concerned and was freaking out when i steam cleaned my engine and saw crap on my oil filler cap and water droplets on my dipstick. i guess a perfect time to do it is when your gonna change your oil right after as well.

 

What's up, I tried this steam cleaning method and I too did not see no steam or smoke until the end when the gallon was almost done I seen a little blue smoke out the exhaust. I used a boost gauge vacuum line,T fitting and a gallon of distilled water. I warmed the car up and hooked up the vacuum line to both the nipples on the UIM, I then had my girlfriend hold the throttle to 3500 rpm and stuck the other end of the vacuum line in the water and the car shut off. Started it back up and she held it to 4000 rpm this time and it stayed running and sucking the water but still no steam out the exhaust, halfway through the gallon my back bumper started smoking by the exhaust tip and I took the line out the water and she got off the throttle about 1 minute after. I gave it about 5 minute to cool then started it again and put the line back in the water, at this time when I looked under the car the water was draining out from I don't know where and the water looked a little dirty (light brownish color) when I checked exhaust I seen little bits of somethings glowing red comming out the exhaust. Could it be carbon comming out the exhaust in bits or maybe I just messed up my cat inside? Now the car was hard starting next day and was running very rich, changed the plugs and wires and its starting up but now sounds like it has a bridge port after about 2 mins cold start and the idle drops slowly then shut off. I get a little hard when I try to start it but not as bad as before and its running rich..also when its sounding like its ported the pfc shows my water temp in the negative only when its brapping lol. Any help to why I'm still getting the hard starting,running rich and it sounding like a bridge port is gladly appreciated.
94 rx7 twin turbo,greddy FMIC,full greddy exhaust,koyo rad,PFC, 10psi,after market dp..think its a M2 dp. Thanks.

I did this... and on the front rotor, i noobed it up... second rotor went far better. It drove ROUGH for a few miles, but came out of it. Was tough to get it to idle, and all kinds of negatives, but as soon as it was worked out, it ran fantastic. It's a scary thought to do, but my dad said that was their old school fix for cleaning out a piston motor back in the days... cup of cold water down a hot running carb, and it clanked, and banged, and smoked, but it does was it was supposed to. He made me feel much more confident to pull it off.

While on the subject, rotor one had a lake of wateron the ground underneath, where rotor two did not. Do i have a bad seal or something?

 

Exhaust leak between manifold and block most likely.

 

To avoid the motor from diyng and to not overrev it i do one rotor at a time.

 

I saw water dripping out where the actuators connect to the turbo, when I did mine.

 

clogged cat.

 

I mean Yearly? or is it based on mileage?

 

I did this 2 years ago. I saw no difference in how the engine ran before vs after. In my opinion, not worth it, when you weigh up the risks vs benefits on an older engine.
Cruising around in 2nd gear at 4000rpm for extended periods every so often probably has the same or negligible benefits as water does.

 

I just read this entire thread and noticed many observed a glowing cat and/or exhuast during or after the procedure. There seem to be a number of misconceptions as to why this is, so I'll take a moment to clear this up.

The glowing cats/ exhaust is the result of persistant misfiring likely induced by the procedure itself. You have excess air and fuel in the exhaust at about stoic and when it hits the cat it reacts--big time, releasing all of that heat into the cat and exhaust. Unfortuantely, there is bad news in this: Once a cat is in red heat like this for more than a few seconds, it is often damaged. Overheating is what usually causes the cat to fail and break up, often blowing the catalyst out the exhaust.
