How to Decarbonize a diesel engine using tap water 

For all who think that this method is worthless , it's so simple .....: Do not try it ! but on the other hand Do not talk Nonsense ! I'm not payed to do this , it was supposed to help others maintaining their engines for Free . And please before posting a useless comment at least be positive , if you don't know what are you talking about keep it for yourselves . And again my engine is still runnig like first day , i do decarbonize it once every year No signe of damage at all ! Any video response that show the opposite of the video purpose is welcome Any unnecessary comment will be deleted Thanks for whatching

OK a couple of tips:- if its a turbocharged car, only spray after intercooler because if you spray from airbox hose it will get sucked through turbo which could damage the blades. Also, if you want to speed up the effect (it can take a lot of water to decarbonise some EGR diesel engines), mix methanol and distilled water 50/50 and get a dense fine spray down the inlet. Much easier and cheaper than removing inlet and trying to walnut blast it.

my husband used to do this trick before registration here in the philippines then he change oil and filter it works passed the emission test

That is one way to crack a cylinder head, break a piston, or bend a conrod. You need to be very careful not to pour the water into the inlet in large volumes, or any of the things mentioned above could happen.

worked for me... before that my car only can 100km per hour or 80km perhour and so slow to move fast...after do this method...amazing result i got..my car can faster 100km to 170km!! its like i buy a new car again...

For all the guys screaming about hydrolocking the engine...not really gonna happen with this amount of water, if you think about the way everything's happening, the rpm, 4 cylinders to spread the water out over etc the risk is minimal, ok, lets do some math to break it down to help understand and show it, say we assume a combustion chamber size of 50cc(so piston at TDC, the air volume left over), and at 3000rpm thats 50 revolutions a second, its also a 4 cylinder so thats 200cc's of combustion chamber volume, he's only spraying say 50 to 75ml of water in a 1 second burst...in 1 second that engine has rotated 50 times, divide that by 2 to get a complete combustion cycle(its a four stroke engine so suck squeeze bang blow) so we get 25, times that by 200cc of combustion chamber volume is 5000cc of combustion chamber volume turnover per second or 1.25 litres per cylinder per second....still believe your going to hydrolock that engine with 50 to 75ml of water? hydro lock situations happen when you try wading your car through deep water and forget the intake for the airbox is low and it sucks in litres of water= more than the 50cc combustion area in a cylinder= broken bits and broken wallet

This is a old mechanic trick and yes it works great....ever seen a car with a blown headgasket???Pistons and valves is super clean!Id use a spray bottle though to create a mist.

I tried this method in my toyota yaris D4D with fap filter, use distilled water in a spray after the air sensor, rev the engine to 1,500 rpm warm engine ,the water in spray went through the turbo, not only did it make me do the fap filter regeneration and the car works better, with better response, thanks

New video here: Same car same Engine,same decarbonization Method : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Z-4zeCRvmbI.html

same principle as methanol injection i assume. i would be afraid of hydro-lock and runaway like this. my heart says "cool!", my brain says "No!".

I used to service small gasoline electricity generators and sometimes tradesmen would leave them idling in the back of a truck [well,not idling they were doing 3,000 rpm in a 50 cycle country or 3,600 in the USA] and with no load, they were clogging up the heads and mufflers. To fix this I used to attach them to a load bank with the air filter removed, got myself a stool,sat down with a "Spray and Wipe" bottle full of water and just fired in a few squirts ever 5 or 10 seconds and watched them belch a load of black soot as the crap detached itself from the internals, they soon got back their ability to give the amps they were rated for.

I inadvertently tried this once and caused major damage to my engine. Bent the con rods and had to be towed home, The water was 2 ft deep and the car was a NA Rover 218 diesel! LOL

That looks incredibly dangerous for the engine! Perhaps with proper spray bottle that makes a fine mist it would be safe but I would certainly not pour water into the engine like that!

Absolute madness on a diesel

Just stick a steam cleaner nozzle in the air duct...and get back to the steam age! Already to temp atomized mist job done

Worked for me, no more limp mode thanks

I just did it on my turbodiesel 130000km on... it sounds better and its much smoother. Easy, cheap, fast and effective!

I used a proper carbon emissions cleaner on my 2008 Ford Ranger & it blew up the thrust on the Turbo $au4,000 for a new Turbo, no way would I use water in it, 👎👎🇦🇺🇦🇺🇦🇺

I'll do it to my boss car

Hydrolock. Use an EGR cleaning aerosol designed for the job. £5.

I first saw this when working on drilling rigs. Motorhand opened air box, took out filter, then sprayed a garden hose in to inlet. It was a CAT3508, an industrial 34L diesel. Black smoke came belching, motor never even slowed down or sounded strained....

Really works,i probe in my Toyota Hilux,hot water is even better,greetings from Chile.

As a owner of diesel car, I like to see others do that treatment... Big no for turbo diesel, for is a chance to break the turbine. Turbine, at exhaust, very hot.... There is a way to increase the power of diesel, and emissions reduction by spraying water in cylinders... Still, is a technology on development.... So... How I clean the pipe, and engine? Outside town, 3,500 rpm, half hour, highway. Gears 3, 4... Inside town, where possible, 3000 rpm, as long as road permit..., Third gear. Constant rpm is a must, inside/ outside town.... Must. This is my method... How you tell is working: an ease in acceleration, and a cleaner exhaust pipe... 😉

We as mechanics in the 70s used to do the same using Redex oil ,do it outside though 😺

This is crazy,it runs the risk of Hydraulic lock in the engine and I would not recommend this method. No No

a great way to greese your muffler bearings

It does actually work because I've taken an engine apart and it's clean. I would use a spray bottle instead. It comes from when we get head gasket leaks into a piston chamber that chamber is completely clean yet the other ones are still full of carbon.

No before and after tailpipe status. Also it is suggested yo mix oil with water so that the valves don't loose lubricity due to water.

The amount of water you used surely got past the rings and mixed with the oil

maybe would be an interesting idea use a painting spray gun. to have a uniforme mist.

I do this on my 2 stroke bike too!! better to use a pump sprayer to provide a mist of water

I have done this on many occasions I use a measuring cup and let temp get around 140 And slowly pour but my experience is with petrol not diesel But the compression ratios are entirely different Note do not use if you do not know what you are doing

I can see why this works because when you spray water through the air intake its sucking it in at such a high pressure that it will just lifts all carbon gunk off etc. Heat and pressure is the key to cleaning things. I usually decarbon things like taking the EGR valve inlet manifold, EGR cooler pipe etc off my car and clean them with oven cleaner followed by a jet wash. I do it that way so i can see how coked up they get and oven cleaner does a really good job of cleaning them.Ive had some good results doing it that way just time consuming. . Id be frightened of decarboning an engine this way just in case id get wrong and start pissing off the neighbours.

this just blew my car up thanks chump.

Doing short journeys is the fastest way of getting carbon build up as the engine doesn't have a chance to get normal operating temp. Using good fuel and long journeys slows down carbon build up.

If anyone trys this use a spray bottle not a bottle this trick is ment to turn the fine mist of water into steam when it reaches the cylinders.

If the vehicle has an intercooler it you would have to inject the water down stream of it. Liquid lock is unlikely but possible. At the top of the stroke there is more than enough space for an ounce or 29 grams of water in most engines. So do not let the engine bog down to much and spray not dump the water.

Are all cylinders / injectors / valves cleaned out equally by decarbonising? Did all the carbon go out of the exhaust? What if the dissolved carbon clogs the cat-con / EGR? What did the dislodged carbon do to the turbo? How much of the rock-hard carbon is actually removed? Can partial carbon removal cause leaky valves or sticky rings?

i done this on Mercedes 190D 2.5 .. now works smooth and fine .. thanks ;; wld bladek :)

Some friend i have, he used to owned a Renault 19 1.9D and he splashed it in the water during a heavy rain, the motor aspired it at the air intake and it wrecks complety, he loved his car but he have to sold it for a few money.

I should say my skoda 1.9 sdi has done 144 400 miles and its made a new motor of it

I can see why this works because when you spray water through the air intake its sucking it in at such a high pressure that it will just lifts all carbon gunk off etc. Heat and pressure is the key to cleaning things. I usually clean out decarbon things like EGR valves,manifolds

Tried this on my 1.9 skoda sdi works fine engine pulls better no smoke a fare bit of steam when doing it but all ok

Cómo lo hago en mi toyota hilux Diesel:1. tener motor a temperatura de trabajo 2. Calentar agua (ojalá destilada) en un hervidor electrico(no hervir) 80grados. 3.Acelerar a 2500-3000 RPM. 4.Con una botella de 1 litro ir agregando chorros a la admision sin bajar de 2500 rpm.5. Al acabar el contenido dejar en ralenti.6. Armar todo de nuevo.7. Salir a una carretera y conducir a 2500 rpm unos 10 minutos.8. dejar el en ralenti 5 minutos antes de parar el motor.9. Despues lavar el sistema de escape con hidrolavador.Mi toyota hilux 2.5 queda suave y con potencia.FUNCIONA lo he hecho varias veces. Saludos de Chile.

Thanks Sir King Abs, I'm thinking of trying it with my Starex I hope it could improve the engine performance. Salamat Sir n God bless you and your family!!!

جربت الطريقه اكثر من مره وكانت ناجحه تماما بدون اي مشاكل مع زياده في التسارع والدوران اثناء السلانسيه، شكرا وجزاك الل خير.

What happens if you use WD40 instead of water?

Water injection for cleaning has been done on industrial diesel engines for many years, and is prescribed by the manufacturers of heavy diesel engines. MAN, Sulzer, etc.

you can't use it in CRDI diesel engine..it has a lot of sensors

This is crazy, meeeen!!

Pour water into hot carbon-caked cast iron skillet. Show how water has no effect on dislodging carbon. Engine deposits are not carbon, but mostly zinc and calcium from motor oil additives.

I was about to that on a fiat palio 1.7 TD thanks for clearing doubts

Good morning to the bent valves

This method was used back in the 1930's and before to decarbonize flat head fords, etc. Of course it works for diesel. Ask any diesel owner who runs water/methanol injection.

Where TF is that place. It looks like Azerbaijan or a similar ex USSR country! Been there so it feels familiar. BTW> Gr8 vid. and yes water is a great decarbonizer that too many have forgotten..

I have to spray water after the air filter and the MAF and before the turbocharger, is it right? I saw somebody spray water before EGR, but mine is after the turbo. So, which is the right way to decarbonize the engine? I have a Ford Mondeo Mk3 2.2 tdci 114 kW. Thanks to all.

The application is correct but please use distilled water..

Do not do this on a Turbo diesel! It will shatter the turbine blades. Only mist water in after the turbo.

thanks my engine 1.9 runs better now :)

Great video

سلام خويا عندي مشكيل في ديمراج . خاصني نعفط على لكسيراتو عاد ندور كونطاك . زائد لمطور كيدير بحال الى باغي يسكت الى حيت رجلي على كسيراتور . ممكن تفيدنا الله يرحم لك لولدين

1/3 WD40 1/3 NAIL VARNISH REMOVER 1/3 DIESEL MIXED UP IN A PLANT SPRAY BOTTLE AND SQUIRT INTO TURBO. IT WILL BE SHINY AFTER THAT.. CLEANER>LUBE>FUEL >>> 3 IN 1

what do you do if you put too much and engine stalls and not start again?

What about a turbo diesel engine? I have a 1984 Mercedes 300SD. I am curious as to whether there would be negative effects from spraying water into the spinning turbo impeller. I am not sure how you would accomplish the same effect if you attempted to spray the water downstream of the turbocharger due to the existing manifold pressure? So, my main question is: "would the ingestion of water droplets damage the leading edges of the impeller fins?"

Hi......this works with benzin motor?i have laguna 1.6 16V. Thanks....

U can buy moly intake cleaner and spray that in.

The water drains into the turbo fan blower?

What made you think, you decarbonized the poor diesel engine?!!!!

How to TOTALLY DESTROY your engine in one easy step!

I wouldn't do this on the modern diesel turbo engines as they are very sensitive....as tou can see he has used an end 80s model diesel car and remembered too that those engines were like the old hammer mills they could run with any or on anything your poured in them .....

Eu não jogaria água no meu motor. Pode dar calco hidráulico

I Would use an atomizing spray, that way it's no different from atomizing diesel fuel via injectors which cannot be compressed either. Have you not heard of water injection diesel and petrol engines?

Hola para que le hechas agua y para que sirve cual es su función.

don't pour it in your engine that can cause water lock in piston you need to atomise the water so it can turn to steam quicker.

KingABS, How about using a spray bottle to spray fine mist than what you shown? Will it have effect? And what about using steam, say from a sauna?

How do you know it works?

سلمت الايادي thanks

THIS REALLY WORKS!!!

will it decoke the precombustion /swirl chamber on idi engines ? :-)

Understand how an Engine works then ask yourself WTF did I do that for .

When I tried this method twice, what happened was that my Isuzu diesel engine oil mixed with water and was milky white

Is this a turbodiesel? Does it work on a 2007 Isuzu Panther Turbo?

A good ride on the highway will do the job much better then pourring water in your engine

I have Ford Everest TDI engine, better I apply the mist water into the upstream of turbo or dowstream of the turbo? Thx

Hi king ABS I've one problem when I remove the hose from air filter then start the engine and race the acceleration it's didn't work engine automatically off.. I can't race the acceleration... Plz help

how long does it take for carbon to build up? does it depend on mileage servicing etc?

using this method will all other parts be cleaned ie turbo

Seriously wounded have been a lot easier to just pop the clips on the air box lift the top and not even have to mess with them clamps besides that you shouldn't be drowning it with that much water because when water expands into steam it expands 700 times should have been done with a mister plant sprayer

Seems to do the trick here. However, this is a rough and risky method. Let's analyse this. The main problem with diesel engines is soot. Most common problem is soot in the inlet tract caused by the EGR-valve feeding the inlet tract with exhaust gas (containing soot). Some people blank off the egr valve eliminating its function (eco) resulting in a dirtier exhaust and more strain on particle filters and/or afterburners (adblue) in the exhaust-system if present. Some oil coming from the carter ventilation system could be clogging up your inlet manifold too. Best procedure is to clean or change those valves and filters regularly. If not already present install a soot filter before the EGR valve. If you can't find one for your car with an aftermarket supplier, fabricate one. For carter ventilation just use one from another vehicle, late 70's, early 80's Honda accord ones can be adapted easily to other vehicles (they are stand alone types that can be bolted to the body and connected by hoses, don't try to modify filter types that were monted on the block, you will just end up making things difficult), for the EGR filter things are a bit more complicated, big caterter ventilation filters could do the trick or an oil-bath filter (as found on original vw beetles) provided you use an oil that doesn't catch fire at those temperatures, sticky enough to trap the soot and is still thick enough so that it doesn't get sucked into the engine. Cleaning the EGR valve can best be done with a good cleaning liquid, brake cleaning spray will do fine aswell (look around for a good price/quality relation). More inportant however are your cleaning tools (it is rather hard to get small orifices and creases cleaned, small ultrasonic cleaners (as for cleaning jewelry) do a wonderfull job and can be bought for less than a 100$ (probably all chinese stuff). If you keep a spare set of valves around, just change the valve every oil change and run the spare while the other is having a bath. That leaves only the manifold difficult to clean outside the engine itself. Some specialist companies are experimenting with gear that can do this with the part installed in the car, but let's be honest, we can only clean that by taking it out and even do it by hand, an ultrasonic cleaner that big would be quite expensive. A spare inlet manifold can easily be sourced from the breakers yard, unfortunately a good spare turbocharger would be quite expensive. For newer cars that do a lot of miles and probably will need a new turbocharger at least once in their lifetime that could be considered. It goes without saying that all this is dependant on accessibility and time needed to replace these parts. The same can be said regarding the exhaust side. A clogged exhaust robs the engine of a lot of power, so running a spare while cleaning the other will work wonders. A good flooring of the gas pedal does get a fair amount of soot out but there's no substitute for a proper bath. Particle filters and other exhaust cleaning stuff by nature restrict the free flow of gas and over time it gets worse (they get clogged up too). A good aftermarket supplier can provide you with a free flow tube and a restrictor specific to your car to mimic the same resistance a brand new exhaust cleaning system (particle filter and/or afterburner (adblue) ) so you can check if you're cleaning gear isn't stealing your horses (they might pass the environmental test but fail the hp test and vice versa or fail both). Once all this has been done we can look at the engine. Here again most problems are not in the combustion chamber but before and after. The in-and outlet canals in the cilinderhead most often are coated with oil and soot as are the valve stems (oil coming from defective carter ventilation and/or valve stem seals (providing you use the right tools, valve stem seal replacement can be done leaving the head in place). As with the manifolds no ultrasonic option here, so grinding milling, chemical cleaners even high pressure vapor can be used to get it clean (make sure the corresponding valve is closed and suck out the debris with a powerfull vacuum cleaner with a suitable adapter. After all this has been done comes the cleaning inside. A thorough cleaning of the combustion chamber can only be done with the head removed (some soot will have stuck to the piston heads but most soot will have stuck on the head side (chamber head and valves) and unfortunately on or around the injector nozzle. Injectors can be dismounted and cleaned with the ultrasonic cleaner, they are rather pricey to keep a spare set around though. Prechamber diesel engines can have their prechambers full of soot. For how to clean that check out Kent Bergsma's youtube channel (he's a Mercedes specialist and knows what he is talking about). As for this method of cleaning an engine, it indeed can give you a bit smoother engine but bear in mind that you only tackle the inside engine problem which is often only 10% of the problem or less and at best you solve it only half. As for risks, if you don't overdo it you will not do too much harm. One word of advice though, just to be on the safe side use vapor instead of water. It will condns in the inlet manifold a bit but once sucked in it will revaporise again as soon as compression begins and mix some oil in the water tank of your vaporiser so you don't distort the oil film in the cilinders too much. If so equiped replace the emission gear in your exhaust system with a straight tube while performing this trick. Conclusion: if you're driving a 100$ banger, do this but use an atomizer. If you drive a car of still a certain value, do it the proper way.

Diesel mechanic here, KEEP YOUR DIESEL ENGINE AWAY FROM WATER, water also does not decarbonize. Incredibly stupid video

Seems to me that all the shit coming out of the engine would plug up the cat converter.

Do not put too much water 🏊‍♀️😁

Does it clean commonrail injector? Or I still have to purge it? What r the parts this method reached?

Thank u

Could make a great ad for Sidi Ali

This isn't any thing new, it has been used for many,many years by backyard mechanics because it works. It can be used on gasoline engines as well. Be careful not to use too much water at one time.

Isn't this trick only for petrol engine's

I'm gonna spray Kool-aid into mine. Perhaps pickle juice. They have the same chance of doing anything productive as tap water.

Use 'tape' water ??
