You did very well, I am a retired ASE Master Mechanic and have done this before.
It does work better if you introduce a tiny stream, the water soaks into the carbon and boils, so it strips the carbon off instantly.
This is not something to do unless your experienced, as it can damage the motor. However, it is better than using chemicals since the catalytic converters and sensors will not be damaged or fouled by the material used, water will be the best choice for me for this reason. Had you introduced the water in a tiny stream it would have worked even better.
Good job you showed it will work, but I already knew that.
James Fenton I wonder if that car has Cats?
Steam doesn't help, it must enter the chamber as a liquid, and turn to steam after soaking into the carbon. this is what makes it work.
James Fenton can you use hot water and a like needle/siringe
Cold water, and just enough to wet the carbon is best.
It has to get under the carbon and turn to steam to work.
I use a squirt bottle from a chemistry lab. A little goes a long way.
Hey, if you don't understand physics, just admit it.
It takes allot of energy to change liquid into vapor. And yes it does work as I described.
Been doing this for 40 years, and have dealt with all kinds of assholes,
Invalidation is a tool of narcissists. Bite me, Frank.
I've done this for 30 years. It works. Just use a spray bottle and take your time.
To all the "hydro-lock" naysayers: For God's sake, do not try this yourself!
Do not ever use any fuel, oil or water additive not specifically listed in your owners manual! Why are you even watching this video? Just reading this post could in fact void your warranty.
Hahahahahahaha.............. That is quality
. Do. Do do ccc c c do c c c c
lol last bit funny , STOP READING lol
I've seen the inside of a hydro locked engine. It's bad..... I've seen a valve embedded into a piston !
people running hot rod car in the 50s used water to remove carbon in engines is works
Excellent results! About 40+ years my buddies and I did this on some V-8 cars, we atomized the water more used about a quart and got Fantastic results as well! Glad to see it back again!!! God bless you and yours!
bill45a1 Summit sells the Water Kits still. I run NOS it seems to Do a real good Cleaning on the Innards. lol
+bill45a1 Wow. What a great positive comment! That's how I felt after I did it!
+bill45a1 Sir is this true on this video,have you tried all ready
mario matura He sure has. :)
Yes, it can be see clearly as day that the steam is doing something especially on the piston 3rd and 4th, the last one was really clean, because I could see some numbers on the piston that were not there before! Indeed, nice job! But I think that is must be done several times to get the pistons perfectly clean. Thanks for sharing!
When i ran a hydrogen booster on my 94 dodge 3.3l It started off at 18MPG. 3 months of runing i was at 27MPG city 33 highway. I removed the system for safety reasons I went down to 24-25 city and 28-29 highway. So i removed the spark plugs and valve cover it steamed cleaned the engine it looked brand new. So the point is water does work well.
Time really helps as well.
Check the location where the EGR valve dumps back into the intake manifold. I bet that the crankcase gases enter the intake manifold closest to cylinder 4. A lot of the carbon is from recirculated crankcase vapor.
Your petrol, in the UK, is much cleaner than the gas in the US; unless we make an effort to buy a top tier high octane gasoline. We use more than 17 different types of gasoline in different areas across the US because of local air pollution problems.
Watch your vids all the time, keep posting them for hobby mechanics like myself. Thnx bro. Just wanted to say that after doing this decarb method, I changed my oil filters and sparks and I never would've thought that... My god, it stopped drinking oil !!! After doing 1L oil every few weeks it is "zero" since my last maintenance 3000 miles ago. Thank you and haters gonna hate, don't sweat it.
I appreciate that brother, thanks for your kind words of support.
wow im convinced, your testing procedure is very scientific and the results are amazing
it does work, im using a small spray bottle with a cup of water inside it and spray it to throttle valve with 5 sec interval every 3-4 sprays. also, my hand holding on the throttle cable rev it to 2k rpm to clear its throat every time i spray (im using carburated engine, Nissan Patrol Y60 SWB TB42)
the effect is pretty much better than before but not significant, the engine idle feels lil bit smoother and my engine was doing run-on before, but after the water decarb method no run-on happened ever since. oh, and no smoke or carbon chunks on the back of the exhaust
make sure the engine is on its operating temprature and only use a mist of water to avoid hydrolock
yes good video as always, I asked for you to do this to compare it to the seafoam product, and you have proved that this has better results, I did this with an old banger we had in the garage, it did make a slight difference, but then I did a different approach, we had some bottles of redex in the garage, so I took the plugs out of the vehicle, poured 250ml of redex in each cylinder, left it soak for most of day, replaced all plugs later in the day started car and let it run at 200rpm till it stopped pushing out the smoke and it was clear, then I did the water test, man a huge difference in before and after, the redex softened the carbon and the water removed it, very very happy with results.
sorry it was run at 2000rpm not 200, my bad
A soak with a good cleaner, then do the decarbonization. Smart. I hadn't thought of that. Did you change the oil after that? With just water alone my oil had to be changed a 1000 miles early and I think your redex would over night do some slipping past the rings and mess up the oil's viscosity.
DE Nichols I didn't let it sit in the bores over night it was in there for about 4 hours, but we run the vehicle for a day or two then we did a full service on it, as it was due for a service anyway, and after looking at this you tube video I tried the redex with the water trick, if you think it smokes after the water or seafoam trick wait till you try the redex one, boy it smokes, but like I said it made hell of a difference.
Baldmechanic I failed to mention that prior to my experience cylinder 1 was 5-7 C degrees hotter than the other cylinders. Immediately, they were all the same. Wish I had a compression test to show higher compression.
Took a drive, and the engine was SO even! It was incredible! When I got back I retested in case the water had just child the hotter cylinder. Totally even!
It got me curious and I checked compression a couple weeks later. Cylinders 1-4 as follows: 178, 170, 160, 150 psi. Cylinder 4 started at 190...as I had done it first at 190, I believe they are actually quite even. The real problem in fluctuation I believe is that the engine was cooling off.
In order tested, the PSI, kept being lower. .. either that or the PSI change was as I was running the battery down. The engine was audibly slower each time.
I wish engines reported to the PCM RPM without being started. That could have even been clearer.
Since compression was where it was supposed to be, I didn't bother with a wet test. I didn't feel the need to lower my battery charge further.
I wrote an article if you want to know what else happened carmilespergallon.blogspot.com/2014/10/decarbonziing-your-engine-with-water.html?m=1
this is what i want ..thanks a lot BMAC VAGS you make this video showing the result before and after decarbonise with water...
keep it up bro...
you are one of my idol...
Thank you, out of all my subscriptions you're the only one to show the piston heads after water decarbonization. My engine sounded loads better after just plain water through a vacuum tube. The car felt better too, but for a video medium you made the right choice to show the difference as a lot of us can't hear engines very well over the internet, you know?
+DE Nichols I've made my own video about this now! I didn't have a borescope when I shot the video, but I have a twist on it, where I show that valves are sealing better via a laser guided thermometer looking at intakes.
Check out my channel. :)
They actually make water injection kits. One for racing applications to give better fuel economy and two to lower engine temps. It also takes more then just one pint for the purpose you're using it for.
The kits are cheap and also have the required spray pattern mist nozzles. There basically windshield washer kits with a switch. They plug right into the air filter box.
Claude Rains Only the junk ones will be considered windshield washer kits. A real one will operate at 200+psi. Such as the "Devils Own" kits. Now those nozzles put out a real mist.
For the purpose they are using it for. You don't need to buy a $250.00 racing kit. As most will just use it once. Then remove it.
But yes they make some very expensive ones. As they use methanol and water mix. With very specific atomizer nozzles.
I have Seen Eric the car guy do this to liked the 2 videos I have seen so far and it's nice to see a UK mechanic on here. Subscribed.
Nice liked the cam approach to show the before vs after. Did it several times along the years in many cars. Never add an issue and engines always got cleaner in the end. Either gas or diesel. For the hydrolock fearing team be aware the only big no no is simply to not dump a gallon of water straight into the guts of the engine. Spray it slowly and steadly with warmed up engine and warm water. Want even more? Spray some oven cleaner foam, let it seat for 5/10 minutes. Then rev the engine by hand a couple of times, put spark plugs back and continue as described. That will be really clean, but be aware oven cleaner foam will also remove any trace of lubricant. So first revs will be "dry". :-)
All the people saying about hydrolocking --- yes that would happen if you dumped an entire cup into the engine. But you're only spraying water into it. You still have about 1 inch at TDC to the top of the valves for clearance so in theory you could have it filling that but then you run the risk of damaging valves etc.
But hell, if you don't agree with it, don't do it! Jesus!
Darren Boss 1 inch! 1 mm more like on a TDI.
Yeah it's WAY less than 1 inch. Did you notice piston tops have cut-outs for valves, it runs very close. 60mm stroke 12:1 compression, 5 mm average clearance at TDC by the math if the valve shut perfectly at the end of intake. Probably more like 4 mm effective.
Endoscope is a good testing method. Well done
I've been using Redex for years. You can put it in the tank and it will help clean the fuel lines and carbs or fuel injectors and the chambers. You can also take out the spark plugs and pour some straight into the chambers. Give it 10 or 15 mins to loosen up all the carbon. Then AND THIS IS IMPORTANT, get a few rags or kitchen roll and before you put the plugs back, turn the engine over a few times to expel any excess. Clean out all the crud that's going to be thrown out the empty spark plug holes, and pay special attention to the spark plug threads. There's no point taking them out and doing the job only to find they won't seat properly because you left a bit of carbon on the thread. Then replace the plugs and start it up. This will cause a great deal of smoke as it burns off,(if it doesn't then you didn't use enough or let it sit long enough) so don't do it at the roadside as you might cause an accident, it really will make so much smoke you won't be able to see across the road. Use somewhere well away from traffic and let it run a while giving it a good revving every so often. When it's finished smoking, take the car for a good run. Letting it warm up completely and give it a good thrash (sensibly of course) to make sure everything is burned off cleanly. It will clean the piston crowns (and rings if you have let it seep down the sides for long enough) and the valves and cylinder head. It will clean up the plugs too, but you should have done that yourself while you had them out. You should have checked the plug gaps with a feeler gauge too. (you lazy person if you didn't.) Remember, prevention and maintenance is better and cheaper than curing a problem. Especially if you break down and need towing somewhere to fix it. I should start my own channel. HMM I'll have to think about that. Time for a cuppa I reckon. Tara...J
Eric the car guy on TH-cam has done this for years and he is a top notch mechanic. Scotty Kilmer uses Gumout Multi system tune up in the gas with very good results
You could use a 50/50 mix of water and methanol will give you better results this has been on the tuning scene for along time and most heads we removed using this method were very clean
I have noticed on engines with blown head gaskets pistons on affected cylinders are spotlessly clean showing steam cleaning works!!
I would like to see another crack at it but with some changes like hotter engine, best if after a longer distance, and water supplied in a steam state. Maybe hotter spark plugs ? This shuold improve the process of steam clean.
This actually works, but the engine needs to be warmed up, better after highway driving, so the intake manifold is hot enough to turn water to vapor, and getting a cup, and using a vacuum hose for better results.
On the older cars we used to have back in the 80's (I had a 1970 Mercury Cougar with a swapped 390 and a 4 speed) we would pour a little Automatic transmission fluid down the carb, gradually at first, then more and more, basically til it quit at idle, then let it sit overnight, so that carbon would have a chance to soften. (F-Type works best by the way and it's also good in the crank case, about a pint or so, if you have a sticking hydraulic valve lifter.) Next morning, a bit of smoke and almost all the carbon would be gone.
Decarbing with water will work. Although you will get better results if you use something to help break down the carbon deposits. You don't just want the piston crowns clean. You want the rings and the valve seats to be really clean. That's where engines tend to lose most of their power.
Excellent video! I'm a little concerned that number 4 cylinder might be getting the majority of the water. That last one was the most typical of the water action on the cylinder. The problem I have with the booster vacuum hose is that it might go in the manifold right in one arm of the manifold or really only allow one cylinder or small number of cylinders to get the water. See if the intake manifold has vacuum ports on each intake runner. Then try it one at a time? They should all look like the last one. perhaps more of a higher pressure mist? Dunno, maybe more water over a bit longer time period as the cleaning doesn't happen instantly. Good job though. love the video of the piston tops.
Well the air going in will evenly distributed between all 4 cylinders so why wouldn’t it be the same for the water?
@@Alexander_l322 Because for perfect distribution you would have to have the water go in dead center of the intake in as small particles as you can get.
If you use a vacuum port it will not be dead center but will be off center and favor the cylinders drawing air from that side.
Did this in our old lawn mower. First, cylinder was oily and black. After using this method I started to see less carbon and the metal part on the cylinder. Just make sure engine is hot before doing this because it works.
KRisTiAn Tzn Seems like these tricks work in Small Engines more. Less Runtime?
Great video. Do they make a bore scope that has a reverse camera so that you could see the valve surfaces?
has anyone ever heard of water injection, Bosch has developed a system that generates the same outcome with the benefit of cooling the combustion chamber for better performance and fuel mileage
Whats the system called ?
Im sure if you used a fine mist nozzle, you'll definitely get a good result. Thanks for uploading.
Just replying to some of the comments. Excessive Carbon build up causes over heating especially "pinging" i think the term is.when you switch off your engine the carbon is still read hot and the engine fires over as if it trying to start. Carbon build up causes malfunctioning egr valves as well as clogged oxgen sensors and catalytic converters....great video....i think if you add some detergent to the water it actually is more effective in removing carbon....a few drops or washing powder thoroughly mixed through the water and a very small amount...
the idea here is to get the engine to operating temp prior to doing this so that the mist will turn into steam prior to compression
The splotch under the tailpipe undeniably showed that carbon was removed.
I'm thinking it could be mostly from inside the exhaust pipe itself... Moisture brought the carbon out of the exhaust pipe. So I wouldn't go by what came out on the floor.
It shows that water vapour does remove carbon from the exhaust pipe and other part that in contact with vapour.
@@rihia1 Perhaps not but I did this on a lawnmower that stalled a lot and it stopped stalling.
Austin Lucas it stopped Joseph Stalin?
Correct me if I'm wrong but the small amount of water is always in ours engines intake - in the AIR specially in the wet day or autumns mornings. Also it has been proved adding steam to the fuel increase power, reduce fuel usage and the engine works more smooth and quiet. There is one old guy who made a steam system in his old Mercedes diesel car - you can find a clip on YT but I'm not sure now are they on English or with subtitles. PS. Sorry for my bad English :)
Good video. Cute car, we don't get those here in the USA.
A better way to decarbonise is motorway dead of night, gun it through each gear aggressively for 5/10 mins and it should clear it, you'll first start to lose power then you'll see a big cloud of black smoke out the back, then it'll regain power. Italian tune up!
That wont clean your intake valves
:-D
That won’t work like you think and it more for DPF filters getting blocked and not for cleaning carbon out
@@Alexander_l322 Worked for me!
Great idea! Water turns into steam and cleans everything in it's path! Carbon build up on pistons can glow red hot and cause pre-detonation! Good work! James
Ok so I commented on another video you had about using this same procedure and u are using the video cam approach here which is good to see. I would hook up a water injection bottle off of your vacuum line and run it for days like this and then see the results making sure you dont inject too much of course.
hello I have a question
which has the liquid ? simple water or ? whats its mix? 50 water and 50 what ?
I would be grateful the information
really good videos .. thanks !
The idea works, but not that quickly.
If you've ever repaired an engine which has had a head gasket failure where there is a coolant to combustion chamber leak, everything in that one particular cylinder will be spotlessly clean - piston crown, cylinder walls (the top part where the rings don't touch), head and valves.
Interestingly, the engine I'm referring to was a BMW M10B18, which had 160,000 miles. The honing was still visible and there was no sign of a wear step at the top of the bores. It went on to live many more years!
Those brown and dark grey areas on pistons or valves surfaces are mainly metal hydroxides mixed with carbon. Those metal ions come from the environment and depends very much on the conditions of the road traveled. Those metal hydroxides cannot be "cleaned" effectively by water vapor nor HHO treatments. It is those curved surface that really matter. But the changes on those curved surfaces cannot be revealed unless we are using high magnification microscope because they are shiny before and after on naked eyes.
fighter planes used it and also carbon builds up on the cylinders and piston rings if there's too much carbon the rings seize and compression is lost plus compressed air in block as well and u lose compression, picture a bottle going up and down in a tube, great vid
WW2 supercharged fighters had water injection and Dragster have used water injection for years (since 1920's or 30's i think). Normally used with methanol , it acts as a combustion chamber coolant allowing more boost , hence more power (or in the planes case the ability to fly higher). It was tried and banned in Formula 1 racing because the engines were making too much power.
Nothing new under the sun, eh ?
What you are doing here is negligible in terms of performance enhancement.
Interesting video tho' , thanks for posting.
Well you have some of it right.In the Spitfire the later uprated engines had water/alcohol injection but it was used to save the engine not to necessarily give it more power (which it did by the way). These Merlins had a two stage supercharger as which was also a two speed unit. When all was well the aircraft would climb from low altitude where the air was dense and the engine control unit would detect at what altitude it was flying at and would allow maximum boost using the two stages but with low speed. There was a seal on the throttle in the cockpit in which the pilot was not allowed to go beyond unless he was in mortal danger. If he pushed the throttle through this it would set the blower to High speed which would overboost the engine in the thick air. The water injection would then kick in to cool the incoming airstream so the engine would not go into detonation. This water would only last for about 9 minutes or so then the pilot would have to throttle back to low blower speed or be at a high altitude where the engine would not be overboosted because the air was thinner there. The only use for the alcohol was to keep the water from freezing while cruising along at high altitudes where it could be -30 below.
Yansa Skip SAAB offered water injection for that turbo cars back when they were SAAB before GM started the rot
Were the F-1 cars injecting a methanol/water blend, or just water? Those engines are doted on, so I can't see water injection as a carbon remover being the focus there. My compression, cold, in my '95 Civic LX is like-new in a couple of the cylinders, but there's some substantial carbon build-up again more than a year after a Berryman's Total Fuel System Treatment application. One of the cylinders was steam-cleaned to perfection after my head gasket failure a couple of years ago, but that's a bad way to go about this. ; ] I;m certain that 'steam cleaning' the combustion chambers works due to the effects of the head gasket rupture. I'm just looking for more input on the water-only process.
this is about cleaning carbon...not "performance"
Yansa Music Channel ive always ntoiced my cars drive "snappier" when its raining out
That's some good results. Works without a doubt. I did it to my BMW 325 d after blanking my egr. Inlet full of black greasy oil, cleaned it out and ran a pint of water through it, left a soot patch a couple of mm thick lol. Gonna do my celica gt4 soon and will inspect with the scope first like you. Did the car run better? My BMW did.
Great vid! You can clearly see the difference its a no brainer! I see the sea foam lovers have piped down, the comments on the sea foam lawn mower test was pretty amusing. Keep up the good work and dont stop making vids! Lol
wow water works fantastic compared to sea foam. Since you can use sea foam in the crankcase and pour it into the gas tank. How much water into the oil reservoir and how much water into the tank to get the same cleaning results? Or is better to use baby oil as you did?
Jamie Kulyk Do you know what is seafoam?
please tell me. Also can you please tell me what water is? OH ya is 1 litre too much to add to
Can you tell me which substance is used to put fires out? Which one rusts out parts?
I obviously don't know anything so please educate me and the other 16 thousand viewers. I would appreciate it.
Jamie Kulyk It depends on the type of fire, for example you should NEVER use water on a chip pan fire (google it). The water creates spontaneous combustion, I am guessing it has something to do with the H2O molecular reaction. Fire needs oxygen more than anything to react. The difference in oxygen level is the difference from an explosion to a light simmer. If its an electrical fire they use some sort of foaming agent. It really depends what fire you are talking about
I have a Question. What is the Fuels Octane that the car Runs? Is there Ethanol in it?
I have found that Running Mobil Gas does the Trick. They put Fuel additives in it. Sub Brands and Citgo doesn't. Plus Shell with their Nitro additive seems to get worse Gas Mileage. I drive 500-1000 miles a week. Noticing the differences became a Hobby.
Pure alcohol is the best fuel and it leaves no carbon buildup in the engine. I converted by 91 v6 Camry to ethanol with a simple kit for $400
This help keep your engine running cooler because of the removal of carbon in the chambers. old school remedy.
Yeah, but the carbon build up on the piston will reduce overall space inside the piston area. Hence increasing compression, hence improving performance.
Videos like this assure that car mechanics will forever have their jobs. :)
terenas1986 I hope you learn more about engines and this method.
terenas1986 terenas - "Failure Rate" Is already built into the Cars. But I do admit new engines are a lot better than the 1970s and Before, Years ago you were lucky to get 100k on an Engine
+terenas1986
200% agree. Just let dem all experiment..
Have you done it befor? I have and had no issues so for, by using a spryer mist of water interval of 10 second for 5 minutes. work like a charm.
That fella is a brilliant video, always been sceptical of the additive videos, put any oily product in its gonna smoke, this has been going on for years my dad was fooled by redex 30+ years ago, great to see hard proof of the cheapest method, seen good results with a little wd40 spayed in till it stalls let it soak in followed by the water, the wd seemed to soften the muck a bit better.
Thank you brother. My video is there to show the facts, no endorsement, no motive, just transparency. Its crazy how many people will abuse you for telling the truth, but i guess that is the cost. Glad you enjoyed it.
BMAC VAGS The haters are everywhere always trying to find fault.Even when the ignorant are given proof they will still continue to assert a lie.Do your do blood. 1 love still.
Mellow- D Appreciate that :)
most soot on piston forehead is from un burnt oil that passes by valve stem due to bad rubber sealant or from bad pcv valve ( if there is not oil can catch)
I opened 4 cylinder engine and I knew that it had bad valve gasket and it burned oil but i did know on what cylinder, one cylinder was very clean without any soot, one was with little soot and two cylinders were very dirty, intake and exhaust ports too
On petrol engine this can cause misfire on cylinders. On diesel? Just push to 3 or 3,5 k RPM and spray water fast. Works.
Is anybody around living in high humidity places who has a view of their pistons??.
Joui Adain
how about living in rainy uk?
Great!!!,Soooo,combustion chambers must be free of carbon deposits.
Is someone there with an engine showing the pistons?
@@gusibrahim6961
Ever heard of an engine air filter?
I live in Queensland Australia! Its always humid. If im working on something /anything i sweat like a dog. I did an expirimental water injection setup on a hyundai excel 1.5 litre twin cam. Over 300000 km engine.put my borescope in each cylinder and everything was spotless. You can spray more in but dont let it bog down. If i could upload pics. Welll?
Three things. 1. What is the name of your intro song? 2. Do you think this process would be enhanced by using a high octane fuel? 3. Do you think using Coca Cola would be more effective then water? Also i just subscribed as your video content is superb. Cheers!
i think higher octane fuel is better for your car overall, and to be honest its all that i use. Not because I am rich, but because it is better for my car period.
also here are the details for the intro song shop.bmacvags.com/collections/music/products/bmacvags-intro-tune
BMAC VAGS why do you consider higher octane better? Where I liver I have the choice of 87 89 93.. I got with 87 due to my truck and car not being a hot rod. To my knowledge the difference is detonation factors as 87 fires easier and 93 takes more compression.
My understanding is the higher octane fuel burns cleaner, so you get less residue and better performance from your car.
Higher octane fuel burns slower. ( Faster burning low octane fuels create detonation more readily as well as less complete combustion.) With the slower burn rate, combustion is more complete. Incomplete combustion is what leaves carbon residue in the cylinder.
Whoa whoa whoa. I like how that gravel is held in a "mesh"! I never thought about that. Man i need that for the pea gravel beside my house!
this dose work but i put some anti foam detergent in the water - only two drips to one liter also i fixed it so it dripped in to intake while i drove from my home to blackpool that's 120 mile trip - we looked with a ender scope and the cylinders were shiny as new - what prompted us was everyone mentions the effect of a blown head gasket so we tried to simulate that - so yes it dose work well over a period of time - be careful though. the detergent was anti foam carpet cleaner !!!!
well I was changing the valves on a Renault/Dacia Logan 1.6 8v, and some water was left on 2 cylinders for all night but no on purpose, it was something that just happened and I have to say that those 2 cylinders had a lot of the carbon loose, I just had to put my finger on top and it was clean
thank you for your experiment i was very skeptical
Get the engine to operating temp and then just hammer it in each gear... Don't be afraid to hit the limiter but try keep under it.
Why is there an ARROW , on the left side of the screen , on the piston head.............@4:57
water > seafoam
How about instead of a conventional air filter, you could use a retrofit carburettor which you could regulate yourself, and it would atomiser anything you wanted to spray into there, like seafoam, de-ionized water, screenwash, anything, really. that way it's built into your block.
and are you REALLY sure that no damage is being done when you do this?
I think if you didn't rev that much the outcome will be better, giving the water time to soak a little better .. or just do this a bit longer like 15 minutes instead of 5 min?
Hi thanks for the video I've tried it twice and great results as my diesel merc is saying an egr problem. I've changed it with second hand but to no avail tried all the cleaners to which lasted 24hrs and water has been few weeks before problems resurfaces...my question how often would u do this to a car???
I am doing a test right now to see how well standard ATF cleans a DI fuel system. I put a quart of ATF in with a full tank of gas today, and I will post a video soon. Maybe I need to give myself a Christmas / birthday present and get a camera!
Seems the water seems to all go to the cleaned piston. Maybe if the water was steam before you added it it might make its way to the other 3 pistons.
Piston #3 is much cleaner probably because the intake runner is sending a little more of the water to cyl 3 than the others. I would do the treatment a few more times, then every few months to keep the engine clean. I found this out yesterday that Berryman has a combustion chamber cleaner product that uses a combination of solvents and WATER to remove carbon. Perhaps a look at the MSDS for it will lead us to an inexpensive lethal punch for carbon! Keep up the good work my friend.
Great Video and very good quality the pictures. Thanky you.
ive never seen that car before, nice 1. bet its a fun little car.
Does this method affect the piston rings at all? Or does any of the water get down past the piston rings? Or cause any sort of rust or wear on the rings or other parts in the chamber?
Also, wouldn't this affect the O2 sensors and cat?
Always love the helpful vids especially when it relates to a VW. I've got a 2007 VW Passat, I think I have a BYP engine. The air filter is attached to the engine cover but I'm not exactly sure of the throttle and whether I can hand throttle it to spray in? I don't want to muck anything so do you have a helpful tip on doing it on your own? My 5yr old daughter wants to help but is still quite not ready to rev an engine so it'll be a one person job. Thanks!
what is the solution mixing with water? i mean what is ice blue liquid in the bottle first? can we use this methot both with gasoline and diesel engines?
Wouldn't carb/choke cleaner work better? IDK but it seems like it would. It sure does break through the crud and varnish that accumulates on the inside of a carburetor and does a good job on the outside also! Any thoughts? Maybe it would be harmful to engine sensors, O2 sensors etc?
Decarbonization isn't done by dissolving, the rapid expansion of liquid water into gas knocks free the carbon physically.
Can you pls. do a video for B6 Passat. there is no hose as everything is moulded and I cannot see how to do this? -any help would be gratefully received. Thx.

Hi. I looked on your channel for a related video for the 2.5 v6 TDi, but i didn't find anything.
I have an 2001 Audi A6 2.5 TDi with 150bhp and an milage of over 387.000 km and I would like "help" it's engine to work for a few more great k's. Can you please guide me with some tips? Or even better, with a video?
Tks, Peter
does this process damage the cat up top connected to the exhaust manifold? if the carbon is breaking up into "chunks", would it clog up the honeycomb in the cat?
+LiquidSword agreed. I thought I was crazy for a sec
Or just take the cats off.... It's like 4 bolts.
Just a hypothesis, but if you look at the deposit it made on the ground, it's not chunks. It's more like an emulsion.
In my opinion, if you're going to do this, you might as well do it until the combustion chamber is sparkling and do it long enough to keep it all in suspension so that it passes through the CatConv and so that the O2 sensors don't end up fouled.
nice work! you think this will work on a 91 jeep cherokee with stuck piston rings? I'm having blow by..... did headgasket but forgot to do the piston rings. do you think this could clean them?
Hi great and Informative Videos that you make. One question, do you think that if this decarbon method is done say once every 14 Days that it would be a Good idea? Judging from how it did Clean the combustion chamber in the Vid, it would continue to get it even more Cleaner if done regularly?
Hey I really liked your borescope! where did you get it and /or what is the brand of the camera? Thanks
Thanks, my p registration toyota hiace failed its mot on emissions and I did the water decarbonisation, change the filter and it passed the retest with flying colours. No more big black smoke pushing out the exhaust and the engine sounds sweeter. Thanks again :)
Will it be ok to do this procedure on my 08 vauxhall zafira cdti 150 brake horsepower if so can you do a short video of how to do it please. Cheers
Si Williams That is excellent to hear.
BMAC VAGS Hi, what will happen if i put vinegar instead of water? or 50 water and 50 vinegar?
Vinegar is a very good cleaner at high temperatures
Radu Serpu To be honest, I don't know. Try it and tell us the results. You may have a good point.
BMAC VAGS I really have an important question. I have an audi a3 2004 2.0 TDI BKD engine which stutters and chokes when stationary sometimes making strange noises. I really dont know what it could be and alot of people tell me alot of different things. I have it on video and i can show you if you like. Thanks!
Brilliant test! Great video!
good luck with a cloged up catalizer with carbor after any any kind of de-carbonizer work... all that removed carbon has to go somewhere...i bet some of that ends up in the catalizer honeycomb shaped ducting
that is very effective that steam cleans the interior of the engine,its better to use a steamer so the steam enter hot and clean egr and all components ....thanks a million
Thanks for watching the video
BMAC VAGS Can i do this on a 1.5 DCI engine Spraying into the intake tube after the Maf sensor ?? As my Clio is quite Smokey under acceleration (Black smoke)
Hi I love this video, I was told in auto school this would help clean an engine if there was ever any carbon build up. However, I had another question, I have a P0420 error code, something on the bank 1 front or rear 02 sensor might be malfunctioning, or catalytic converter is malfunctioning. I was told in school that do this would help clean out the o2 sensors if they had a bit of carbon on them, what do you think? I think this is the easiest thing to do along with checking the 02 sensors while the engine is running.
+Drew Nelson I seem to have more oxygen sensor failures near the use of water decarbonization. I'd look at the live data see what's really going on and if you need a sensor replace it. Wouldn't hurt to do a water decarbonization first. If you already know you need a sensor then you won't have to worry about damaging it.
I've had an upstream O2 sensor cause false P0420's, it does happen. I've manually cleaned an O2 sensor to have it working perfectly. It failed within 3 days. Yeah, it helped get it going again, but it being clean used the last of what it had left to give. All I did was clean the outside up a bit, the part that goes in the exhaust stream.
im wonder how far is the water going through the system but on another note after seeing cylinder 4 it brought me so water is the way to go
How will this breaking up carbon goin' down the exhaust pipe affect the modern cars fitted with a Diesel Particulate Filters (DPF) coz if you have a lot of loose carbon deposits goin' righ into DPF you could risk cloggin' it wouldn't you?
Another thing is how does the water affect the bore in the cylinder, water in the cylinder could cause more friction so I'd be worried that it could potentially cause premature wear in the cylinder.
Hi, what will happen if i put vinegar instead of water? or 50 water and 50 vinegar?
Vinegar is a very good cleaner at high temperatures
You car and everyone behind you will smell like vinegar
That car is like birth control. You ain't gettin' laid driving around in that thing. No way, no how.
First, I praised your very useful video clips and have a question bindings this video. Which is what the liquid in the bottle which mixed with water? I watched the clip when you are working on the same diesel engine but with only water?
Maybe if you did this once a day for a week . Would it have got rid of all the carbon?
hi, it is the same procedure for a carburated engine..? txs in advance...!
great job brother ,, plz can you help me , i wanna adjust the valves on my 2007 toyota camry if u have any video kindly let me know .. thanks bro allot .
PS. Or attach a link to a picture showing where to spray the water. Cheers.
Si Williams In the intake after the MAF, most cars are built this way
The problem with decarbonizing your engine with water it does work but a lot of carbon breaks up gets stuck in your piston rings valve seats and most of all your catalytic converter it will plug it up
I'm a mechanic I would not recommend this. Reason why its because it will pick up all the carbon and clean the cylinder but some of it will get crushed by the valve against the seats. This will reduce your compression. And by doing so you will use up more gas in the long run. Worked in a machine shop saw it in cylinders that were burning water bad seal on valves
It cleans up the CRUD and rubbish for almost nothing $$$ wise, that's all that matters. The engine wasn't that dirty (inside) to begin with so of course the results are going to be minimal and almost unnoticeable..............BUT IT WORKS.
Brill vid before and after a lot of people recomend using a wallpaper steamer to do this as the vapour gets sucked in and will not hydrolock an engine would love to see you do a 1 hr test with this method at just idle with before and after images
