Re: Decarbonising Engine with Water. Please Explain Again... (paul79)
I wonder if sustained shots from a Windex bottle down the carb might be "not too much."
that is the way i did it. i've done this a couple of times. both times i blew black crap out of the pipes (no cats). i will be pulling the heads off soon for a fresh set, will let you know how things look inside. :smash:
Re: Decarbonising Engine with Water. Please Explain Again... (paul79)
I am letting Marvel Mystery Oil do its thing in the cylinders for about four days. Then I will take a good run/drive and try the water treatment. The objective is to free up any possibly carboned piston rings. This is band-aid stuff I know....See my thread on oil consumption.
Re: Decarbonising Engine with Water. Please Explain Again... (paul79)
I have never done this so this is not of any help in the process of how to do, but please remember that water is not compressible. Too much will definately do some damage to pistons, rods, rings, etc. How much is too much????
Re: Decarbonising Engine with Water. Please Explain Again... (paul79)
OK, I have to ask:
Does the water method do a better job than these carb/FI cleaners (Redline, Chevron, RxP, etc) you can find anywhere? The problem I have with any of this is that you have to tear down the engine to see if it worked.

How would you do this on a fuel injected car? My daily driver (a '93 honda civic) has about 160k miles and probably needs a good cleaning like this, but I don't see how I could do it. Please advise.

Disconnect the brake booster hose and let it suck it in through it. You need to stick a small hose into the booster hose so it doesn't suck too much. There are also some setups you can buy that have a valve you can adjust the rate with.
Re: Decarbonising Engine with Water. Please Explain Again... (zwede)
Well, I just tried doing this and nothing happened at all. I used this procedure..........
I use 12 oz in a plastic bottle. Rev & hold the engine at 1500-1800 rpm and start trickling it in. You will notice the rpm start to decrease. Pour as fast as you can without the engine stalling. Just adjust the rate if rpms start going low. After the bottle is empty wait a few seconds until the rpm pick up, then rev to 3000 for a few seconds. You wil lprobably see smoke coming out the tailpipes after you let it come to an idle, but it will clear up after a few minutes. On dirty engine this can produce quite a smoke show, so don't do it next to any open windows. :)
I didn't get any smoke show...... actually there was no smoke at all. My only guess is that my engine is already clean. Since I bought her, I have ran several bottles of carb cleaner and fuel system cleaners through heras she was running a bit rough (I think from sitting so long - laquer build up. Anyways the good thing is she still runs like a bat out of hell. My buddy was over when I did it, he thought I was nuts for doing it. He told me most people try to get the water out of their gas, not add to it. :lol:
Re: Decarbonising Engine with Water. Please Explain Again... (VettePower)
WOW....here's my 2 cents...if water worked to ,i assume you are doing this to clean out carbon buildup, then why do mechanics waste money on engine top cleaners and products with chemicals in it? i think you might get a very very small benifit from water..if you pour the water in too fast and it all or a good part of it travels into one cylinder, good luck compressing that much water into your tiny combustion chambre..Kaboom...i wouldn't...buy some cleaner and follow the instructions on the can...if it sounds too good to be true.....
Re: Decarbonising Engine with Water. Please Explain Again... (paul79)
I can see it now. In a couple of weeks there will be a lot of posts like: My car was running fine until I poured water in the engine now the ……….is making a loud noise! :eek:
Re: Decarbonising Engine with Water. Please Explain Again... (PaceCarTN)
I've used the water trick many times, works like a charm... like the guys said, a few ounces of water... it will run rough for a while, after that.. should smooth out a lot
I have also used top engine cleaner (gm) and a few others... the cheapest is the water...
I also used something similar to the top engine cleaner in an 86 honda... the heads were all messed up, pulled the heads, put in enough to be even with the top of the block... at first the stuff just drained into the pan... IT RESEATED THE RINGS! just used a rubber hammer and a piece of wood to bang on em a little...
I was really suprized about the whole thing... car ran like a charm after words
I've also seen people run tranny fluid for oil... extremely clean... just run it till it turns black. It cured a lifter tick and power problem on a mechanic friend of mines buick V8.
If my engine wasnt already apart... this stuff would have been done to it... but gotta go at it the slow way from now on out :cry by hand... man i'm lazy

Doubters of the benefits of water injection, particularily keeping things new and shiny looking, should check out the following web page: http://www.aquamist.co.uk/
Will probably add this setup next year to the L88 to help offset low octane gas.

This company is also making a water injection unit to equip all the new Bentley Turbos, just in case some might think this is a snake oil system. If it was good enough for Rolls Royce and Merlin engines in P51's and Spitfire's as well as new Bentleys, I will take the chance on mine :yesnod:
Re: Decarbonising Engine with Water. Please Explain Again... (paul79)
To my knowledge water-injection is used in aircrafts.
Also, in two-stroke outboard engines it's quite common to have a leak at the lower crankshaft seal, causing water to be sucked in.
The piston/cylnders/sparkplugs then become shiny clean...
