Tried to clean the engine by injecting water...

[tancred]

So, today after doing some research about using water to clean out my engine I started off with a bottle of Aquafina, 50 / 50 Water alchohol mixture because I didnt really trust the idea of letting my car guzzle water, so I figured at least the alchohol would burn and make the risk of hydrolocking my motor a bit slimmer...so I let it take 1/2 a bottle through the TB port vac line that we all feed Seafoam through and then I fed some through one of the 3 blocked ports on the rear of the intake manifold. I didnt get any change in anything from the TB side, but when I connected it to the rear of the manifold my car began to buck and sputter and shortly after a **** load of smoke came out and I left 2 streaks of carbon on my driveway..... So I decided to stop with 1 bottle, and take it for a spin. Car acts fine, drives fine. I cant say an improvement but deffinately not any nasty side effects. I drove the hell out of it for about 15 minutes and brought it home. I am going to give it some more water later today, maybe 1/2 a gallon or so, I am debating if I should run 2 vac lines, one to each port to try and feed the engine evenly. But I am going to continue running 50/50 alchohol water mixture this run. I may try straight water later on.....

why are you doing this?

[tancred]

Because of some posts about steam cleaning engines by injecting water, and a few people asking questions about whether or not it works, and how much water an engine can inhale.

muscle car guys used to do this back in the day. works the same way as water injection but you need to do it a lot to have any effect.

[Enthalpy]

It does work. Water at high temperature can react with carbon creating, eventually, CO2. The CO2 gas exits the chamber harmlessly.

The emphasis is hot. This is probably best done on a dyno with water injection under boost, instead of at idle with a vacuum line. For one thing you won't hit all cylinders with the vacuum line.

JekylandHyde had fantastic results with water injection and a sparkly clean set of combustion chambers.

i dont think you're grabbing the concept of hydrolock. the piston goes up for the compression stroke without the plug firing at all, no burn is occuring. whatever is in the chamber is getting squashed, alcohol has just as much chance as hydrolocking as water does.

a vac line cant carry enough water to hydrolock anyway. if you do it thru the vac lines, the chances of hydrolock are very very very slim to impossible.

it works though.. i usually suck a litre or so of water down, and then proceed to seafoaming.

[tancred]

I understand hydrolocking, I just didnt understand the quantities involved, I had this idea that a cup of water would cause the engine to have issues. Because of the article I read about not being able to compress water. Ive never heard anything about not firing being involved.

Anyhow though I was just worried it would cause problems, so I was being careful. But I was mostly just trying it to see if it did anything at all or was just a buncha shitake.

I didnt do it at idle, I did it at 4-5k with 2 vac lines into 1 gallon of water, one on each side of the engine, then took it out for a beating...

People who freak out over cold air intakes getting wet are pretty misinformed, I watched a video of the owner of AEM put his cold air intake into a bucket of water on his personal NSX with a bypass valve installed, the car still sucked up several cups of water and ran just fine, to actually lock a motor, we are talking about driving a car through 2ft or so of standing water and applying enough throttle to pull the water into the engine in huge amounts....enough to submerge the entire intake orfice for several seconds.


Still learning, I admit it!

lol... go ahead believe that... you believe that so much try it.
he got lucky and water was distributed thru 6 differently cylinders.

**** around and get those two cups of water to get sucked up by the No. 1 intake runner and you have a different story to tell the lil kids that follow you.

top end cleaning

2000 rpms
use ATF not water.
i so strongly disagree w/ water. correct it does work in small amounts. but very bad for pistons if done incorrectly.

not matter wha you use you need to do in small amount and slowly. the liquid your using need to atomize with the air before entering the cylinder. so that when you think your doing this top end cleaning right and all your doing is making a puddle in your intake manifold so that it can be sucked into the cylinder all at once and cause hydrolock.

if your smoking from the tailpipe your doing it too fast. it should be slow and long... should take about 45 mins to and hour. using no more than 1 qt of fluid.

anyone tells you different just doesn't know what they are talking about

[TomsMR2]

how exactly do you expect to atomize ATF? might work if you have an injector and HIGH PRESSURE atf being shot out of it. anyway else, no.

explain how water is in any way, shape, or form bad for pistons. its not. at all.

water works just fine. if you think it doesnt, you are wrong.

This Is One Of The Best Ways Of Doing It.

ok no,

ATF is a liquid... you can atomize any liquid. that is why you do it in small drops in vacuum... the vacuum will help seperate in small amounts.

now imagine a hot piece of metal... around 1500-2000 degree.... something like a combustion chamber, then you drop water on it. and that piece of metal aka your piston cracks from shock. like the hot frying pan in the sink.
ATF is a high temp lubricant. it is designed to handle heat.

all your trying to do is soften carbon so you can burn it.

your not using the liquid applied to actually clean anything.

i am right... cause i been doing it for years and seen it... not read in import tuner mag or some message board.

so, i am right

yea and that throttle body cleaner will kill a car w/ drive by wire...

very true... anything is possible you just need to know how to do it...

awesome. i guess all that injector R&D used is useless. they might as well just have hoses spraying gas in.

now imagine a hot piece of metal... around 1500-2000 degree.... something like a combustion chamber, then you drop water on it. and that piece of metal aka your piston cracks from shock.

yeah.. that doesnt happen. you know COLD GAS is injected into the engine right.. new direct injection motors pretty much flat out spray the piston with gas. people have been using water injection for YEARS now. theres no risk, theres no "shock".

i am right

no.
