yet many people have noted positive results like increased vacuum and compression and cleaner emissions.

there are no gaurantees with anything in life, sometimes you just have to assume that there may be risks. with this basically the only ones being oil seals may fail(very uncommon i would say) and water may get into your oil(preventative by doing an oil change immediately after even though i haven't noticed much water intrusion). or for the ones who are trying to prove me wrong, i'm sure it is possible to collapse a rotor or blow out a seal if someone is persistent enough to try and force enough water into a running engine fast enough, which basically none of the vacuum ports, even the brake booster i would say can get you close enough to cause any damage.

if i was really that worried about it i wouldn't be doing it in the shop or you can sure bet i will eventually have someone trying to prove me liable for a blown motor.

but yet you still claim that the water isn't doing anything? well then that is your opinion yet several of us have pulled apart motors that surely should have had some carbon in them after 30k miles yet didn't, only thing in common being water injection.

 

UPDATE!

Everything fine now. No smoke anymore. And for your info it's take about 3 min for 2 liters at about 3k rpm per rotor (for me)

 

sounds like something id like to try before my next oil change!

 

I made a diy steam clean video about 9 months ago. Ill post it when photobucket fixes their site (maintenance)

 

A healthy discussion about this is fine. But again, if your considering doing this, don't overlook installing a simple boost-activated AI system. Not only do you keep things clean, you will viturally eliminate knock. And the systems aren't that expensive.
And Ryan, these systems were developed and sold by multiple manufacturers for NA and forced-induction piston engines too.

 

I wasn't arguing against ai systems. I was arguing against people shoving un-metered amounts of water into their engines.

 

well, in all honesty there are many threads on the subject and thousands of people's replies to it, none have complained about any internal engine damage due to the treatment that i know of. there have only been a few that showed some damage due to overheating the exhaust due to not letting the engine cool between each treatment stage.

even i have gone a little overboard and not let the exhaust rest between passes and had one car where the sound deadening just above the cat started to smolder, that's about it.

funny thing, the exhaust overheat light still did NOT come on... lol.

 

Heres the video's I made. I have pictures as well .....actually i'll just post them below it. Hope this isn't thread jacking..

In the actual steaming process

Just click on the vid, it'll take you to my photobucket then click on the pause and play button on the video screen and it'll start. don't mind my narration... I get nervous haha.

 

Easy test for you! Do a forum search for steam cleaning and count the number of threads. Now do a search for anyone blowing or damaging a rotary while doing steam clean and you probably wont find anything.

 

Alright, well I got around to doing this today, ran 3L of water into each nipple. I drove around after to try to get rid of as much as possible before my oil change, and the idle was rough at times. I changed the oil, and have been driving for 4 hours tonight (just got the car back on the road!) and I can say not one problem. I honestly can say my idle is much smoother then it was last year, I should have done a before/after compression test but did not get around to doing it. Overall Steam cleaning worked great for me, I did not time how long 3L took but It was somewhere in the 3-5 minute period using a 1/8" vac hose. I will be making this a new standard every time I bring my car out from winter storage. Worked great, was simple and on a side note I found out I have an exhaust leak from seeing the steam come out under the car. That is next to fix then I am good to go!

 

I did the steam clean in the beginning of March when I brought my car out of winter hibernation mode. I only did half a gallon per rotor, one rotor at a time. Took about 2-3mins per rotor while sitting in the car keeping the rpms at about 2000-2500. I changed my oil and spark plugs right after (I was going to do those anyways since I was pulling the car out of hibernation) I didn't notice any water in the oil and my spark plugs were still fouled pretty bad. Anyways once it was all done and I drove the car home it was a BEAST!!! It revved so smooth through the rpm range (could have been a combo of all three things oil, spark plugs, and steam clean). My car has never felt like that and I've had the car about 2 years now, even though I change the oil every 3 months and spark plugs every 6. I will now be doing this everytime I bring the car out of hibernation in the spring

 

I don't think there is a real danger with driving the car around after without doing an oil change after steam clean,.....but something just seems wrong about it. I'll always chang my oil after the steam clean. But like I said,....i usually let the car idle for abotu 5 min and rev it up on and off a few times then change the oil. Something about water being in the oil system and being under load doesn't sit well with me. But i'm no mechanic either..

 

Anyone here done steam cleaning with the OEM cat?

 

I have an OEM cat and just did this process no problems. Car is JDM, not sure if the Cat is the same or not, but no problems for me.

 

Dang, since you have OEM cat, you should have smelled your exhaust before and after. That's something I never did in the past. Ya never know, steam cleaning may be something people could do right before a smog inspection.

 

I suppose, would be good info to know, but hey no worries for me. No smog inspection in my province :-)

 

I have the OEM cat on mine too, but also have a J-Spec. No problems when I did the steam clean though.

 

Is there a reason you guys don't use seafoam? I didn't see it mentioned at all in this thread.

 

Seafoam I am not very familiar with and chose water for that reason. Based on the threads I read through the "popular" steam clean used water, I have heard of Seafoam being used but found a lot less posts on the particular subject. Perhaps someone here with some more knowledge on Seafoam VS Water steam clean will chime in.

I chose water simply because that is what I read about and its very cheap and easily accessible.

 

I use seafoam on all my cars every 3rd oil change and it works wonders! I havent used it on my fd yet but once its up and running i wont hesitate to do so.

 

great thread on steam cleaning the engine, plan on doing this at my next oil change which means i have enough time to hook up my boost gauge to get before and after vacuum reading to see if any difference and maybe do a compression test also.BTW this thread should be sticky.

 

uhhh....
it may not be a good idea to clean the inside of an engine, idk, but everything else in this world can probably be cleaned with water, steam, or a pressure cleaner
for instance, carpets, your car at a carwash, turtles, money, underwear. etc.
of course. you should use soap.

I wish I saw this thead last month
might have been good to do before

 

I've done this procedure a few times before but I've since started premixing. It did make a huge difference when I did it the first time. Smoother idle and revving.

 

I also performed the steam clean procedure yesterday and changed the car's engine old yesterday after doing this procedure.

I used 1 gallon of water and I steam cleaned both rotors at the same time. My car still has the stock main cat and I did notice that my cat-back exhaust was glowing red by the time I was done.

So far everything is okay. I mainly did this to pass MD-Emissions test.
