This is the best hydrogen carbon cleaning vid on UA-cam! Thank-you! Please do more on carbon cleaning engines!!!
I have one coming up soon.
I had UK Carbon Cleaning (UKCC) come out to do a stage 3 clean on my Stage 1, 2008 Audi TT with 70K miles on the clock and no record of the service being done prior. The car felt amazing after the service. Smooth acceleration, punchier whilst offering a much more refined power delivery. Highly recommended.
The best way is to take out intake manifold, EGR valve, and physically clean them and also intake valves. Simple brushing will do.
That's what I did in the end with walnut shells. I've done a video on that too.
@@ConquerDriving please share link to the video
Usually when you test an engine for how nice and smooth is running you should do with half load not full throttle. Full throttle can show you much on the Dino but not when you are driving . Most common mistakes when people buying used cars, drive slowly to find out how the engine performance is, good or bad.
Excellent. Thanks. Saved me £99.
You're welcome ☺
The combustion happens in the chamber and the valves are closed. Therefore one cannot clean the valves or manifolds using hydrogen cleaning.
I understand this, they claimed to clean the intake valves, this is why I put it to the test.
@@ConquerDriving they claimed wrong ask for a refund
Some new engines use both direct injection and port injection. The ECM or PCM switches between both to take care of the valve carbonization. That is what the manufacturer says. I am surprised that HHO did not clean the valves better. Look forward to hear from you about what works better on cleaning the valves. One last thing to say, many shops I know use crushed walnut shells to blast the carbon from the valves and seats. Good day and stay safe too. VF
Thanks for your comment, I tried a chemical and walnut blasting and made videos on both.
@@ConquerDriving How about using carbon dioxide gas for blasting ??? I have seen this used in limited applications with great success. Was wondering how this would work on engines ??? Since the blast is gas there is no cleanup from the medium used. Just an idea for you to consider too. VF
I've not heard of this. I guess you would have to be careful for health reasons. I think inhaling 12% CO2 is deadly.
@@ConquerDriving I have to apologize to you fella. Was not clear enough in my statement. I am talking about using CO2 frozen carbon dioxide cleaning. This would work superbly and leave very little cleanup needed. Well that is my idea, if it works bet you lots of others will be doing it soon. Good luck experimenting. Thanks for for understanding and peace too.VF
@@ConquerDrivingcan I get a link to the video with walnut blasting?
Great vid to see if Hydrogen cleaning works. Answer is that it did absolutely nothing and as for 3 horsepower well there are too many variables to consider that a gain. I would stick to walnut blasting or solvent cleaning.
Oil catch cans are a must have for direct injected vehicles.
I have been doing HHO carbon cleans for the last 18months. I have had mot failure's pass and I have never had anyone not notice an improvement.
I always give vehicles a minimum of 1 hour and problematic vehicles longer. I don't believe 45 mins is long enough.
I charge from £50 which I think for the service is a fair price.
A wallnut clean is better but more expensive.
I wouldn't touch a terraclean in a million years.
A nice video 👍
Great work. Shows that Hydrogen clean is BS
Do you really watched video? 🙂
@@aleksandarpetrovic6613 Yes, and I know by our VAG forum in Denmark that its a waste of money.
If you want to use your money on it I will not stop you. :-)
@@danielfl.9347 Don't be a slave of your own beliefs 🙂 Try it! Just don't use 12V machines, just big 230V are good.
@@aleksandarpetrovic6613 No need to waste my money on it. A test made in Denmark made by an organisation was made and it said that it was a waste of money and did absolutely nothing.
You need to blast the carbon deposits with walnut shells or chemicals and manually clean the valve - heads.
@@danielfl.9347 no one claim that HHO gas clean air manifold and inlet valves. And many tests was made all around the world and prove better performances and exhaust gases. This video also. Of course there some bad machines and mechanics, but this is usually in every job :)
What a coincidence. Our Golf MK7's cylinder head to be replaced at exactly 85.000KM too! We drive one of the earliest build models and sadly had to go through this
Not necessarily a coincidence, as Seat, Skoda, your MK7, etc., Use the same engines and are all VWs.
I do all the time carbon cleaning in my cars. I think it also depends on which company you are using.
Who do you use please Kimo?
@@Chopperdod77 I am actually abroad
Fuel additive LNC from MiaNOX copes well with soot and deposits on valves and in the EGR system when burning fuel with LNC from MiaNOX additive, an active steam chemical reaction occurs in the cylinder, which cleans the particulate filter in a diesel engine and the catalyst in a gasoline engine.
After you did the carbon clean you should have taken it to the redline as much as you can, also use non supermarket fuel and good oil every 8-10k miles and just take it out once or twice a week and again take it to the redline 10+times to help
I drive me car a lot and I do take the engine to red line when the opportunity arises. Putting oxygen and hydrogen through your intake makes no difference at all to the intake valves. Watch my other videos, the walnut blast was the only method that worked.
@@ConquerDriving Fair enough, I had a carbon clean, not by the company you used, just a garage with a machine and ot made a huge difference on my fabia 1.9 tdi on that day after giving the car hell after the clean.
Funny. I did this on my 2001 ford explorer some time ago on my own. It definitely reduced what engine noise I had at 160k miles.
I had this done on my Mercedes C220 CDI year 2011 with 118k on the clock yesterday 09/10/2020 by Gary of Engine Carbon Clean and was worth every penny of the £125 it cost in total to clear an issue of lag from a cold start and a DPF regeneration clean which now is at just 13%. The main reason I had this done was that I was having an issue from a cold start with a lag on acceleration before the turbo would kick in which should not be the case and started just out of the blue. After trying everything prior to having this process done to try sorting this issue out the Carbon Clean process did the job and cleared this issue and the car now runs better than it ever did so the system does work and I'd use again in the future and I highly recommend this service to anyone with a Diesel car. Many thanks again to Gary for sorting my car he's a top man who carried this out and also a complete diagnostics of the car before and after the process and also explained everything to me so well and gave good advice and answered all my questions. So for those who say this process doesn't work they are very wrong, it does work and worth the money too.
I'm happy to hear you're pleased with your results.
It mainly works inside the combustion space.
99£ for this so called hydro clean is silly, you should pay £150-£200 to walnut blast or similar your intake valve heads. Then run the engine with a slight mist of water through the intake for a week and voila, your engine will be clean. Or if you don’t know what your doing just stick to the walnut blasting.
Agreed, I'm doing these videos for some myth busting.
I checked this after seeing the sponsored post on Facebook...... I think its better to manually clean
to really clean the valves you must do a wallnut blast
I did, it worked great.
Excellent video, thanks for doing that
Based on this video - It doesn't work
Hydrocleans do not clean intake vales, its impossible. They clean everything from the combustion chamber through to the exhaust.
They work by creating a mix of hydrogen and oxygen which are injected into the engine during combustion and they create much hotter combustion and gases which burn away carbon and clogged dpf's and cats.
They most definitely do work, but only for the right applications, eg, blocked dpf, cat, gummed up turbo vanes, gummed up o² sensors, exhaust vales and manifolds etc.
I belive what really got cleaned was the catylact converter
I saw at a BMW dealership workshop they decarbonize using walnut shells. Test this method.
This is a very thorough and useful review, thank you.
I'd be interested on a segment about wear & tear on your instructing car. Considering the large mileage covered by a lot of different drivers
That's an idea for the future. Thank you.
And techniques to reduce wear!
One of my mates was taught to leave the clutch half down and creep forward in traffic by releasing the brake.. Eek clutch!
Well to give you an idea a clutch rarely has the chance to wear out, not even 20% worn when I have to replace due to there being play on the spring loaded mechanism in the centre of the friction disc due to clutch/flywheel impact. I get about 35,000 from a clutch.
HHO doesn’t clean anything on the inlet side; it needs combustion to work.
I don't want to spread any disinformation, but I've heard that running engine on high revs sometimes helps keeping it clean. Although I don't think it'll help when valves are already clogged.
Yes, highway driving does about 10% wear on an engine than town driving.
@@ConquerDriving it might be a reason why it happened, since your learners drive on low revs a lot. Good luck with figuring it out, anyway. And keep us informed. 😌
THere is a technology called walnut blasting which cleanes the carbon-build up from the intake valves and other parts. Or use high octane premium petrols. I do not live in the UK, so i don't know your petrol brands. Here in Hungary OMW Maxx motion and Shell V-Power recommended.. Furthermore I personally avoid Direct Injection engines, I stayed at the naturally asperated in-direct old-school engines.
ua-cam.com/video/TgOopW8hfuQ/v-deo.html
I know the one, I'm just trying cheaper fixes to see if they work. Premium petrol won't help because it's direct injection.
@@ConquerDriving Maybe, but they are advertised the Maxx Motion here, that it has additives which cleanes the engine.. who knows maybe this is just commercial.. :)
Hiya buddy. Such a great vid, however if you're not aware, this procedure is Preventative, and not to confused with, as in your case, Heavy Tar Deposit removal. For that you need a Terra Clean, then periodic Hydrogen Maintenance as part of a service schedule.
Wondering if you have an update. I'll check the rest of your vids.
I was going to get this done just to keep everything clean and new inside but will wait until I’m fully on the road but will look at your car insurance
Let me know if the insurance works out as a good deal for you. I am interested in what I decide to promote.
Came upto £2000
From another company it was £1300
@@playuk-tiktok Thanks for letting me know, who managed to give you the cheaper quote? Was it a comparison website?
Interesting video, that carbon Cleaning machine wasn't putting out much Hydrogen judging from the bubbles in the water bottle. TBH there was not much Cleaning done IMHO.
Our workshop machine puts out 400 litres per hour Hydrogen from the HHO crystals and I think that's a lot more than the machine used in this video.
I live in Perth Western Australia and an add for this came up.
All I thought was.... " here we go again "
Buy car , service as recommended and at some point you will want a new one.
Why bother
There will always be some professional come along preaching you need something.
You hit it on the head psychological
Well won’t be getting a clean of that company. I have always done mine by hand. Yes it’s hard work and takes a few days but makes every car perfect! Great video!
2.0 Tdi that’s had its head replaced.... sounds about normal to me either warped or cracked all too common
Had this done on my Alfa didnt do a thing lol. Throttle body was still covered in carbon.
Thanks for the video, the only video that treat the new engine (EA211) from VAG, and it seems they didn't solve the main problem of TSI (all generations). I think that you don't use the right oil or service interval is longer then 15000 km or 1 years, if you using longlife oil, this is why you intakes valve are so dirty. Oil have a big impact in carbon buildup. I have a golf mk7 with 1.4 tsi with 120000 km and it drive like first day, no power leak, just a litle vibration on idle but it has this since new. I change oil every 10000 km or 1 year i put castrol titanum 5w40.
My oil does normally get changed 7-8 months and it's still relatively clean. Never known an engine to keep its oil so clean. I do a lot of town miles and idling which doesn't help it.
Good video. I think they use weak machine and run short time, that's why you haven't better results.
Thank you, they ran slightly longer than normal. I've had good results overall bust hydrogen cleaning doesn't clean relatively cool intake valves.
@@ConquerDriving I am constructor of decarbonising machines, for your car need more than one hour, and they run just about 45 minutes, right? They measure exhaust gas, but this is not true marker for ending treatment. How they run his machine, from house socket (220V) or from car alternator?
Very good, thorough, rigourous, scientific experiment video. Great work
Thank you. I have 2 other videos on carbon cleaning.
There is no difference in appearance.
My question is, are these deposits not transferred to the catalyst?
Does the catalyst need to be cleaned and how?
Maybe you should have shown the carbon cleaning guy the pictures of how bad your valves are maybe some throttle bottle cleaner first would have helped and i would have limiter based the car straight after the carbon cleaning
You could do a much better job with some throttle body cleaner spray, a dental pick and some cotton tipped sticks. Takes about 20 mins a cylinder and it will get rid of all that crap, which you can remove out the top instead of feeding through the engine!
Agreed
Hydrogen carbon cleaning does not help om GDI engines such as TSI. You can use wallnut shells to clean it manually, but this will cost in labour.
Thank you, that's my next job.
Yo saved me a few bucks!! I was about to do it but definetely does not worth it!
I do carbon cleaning for the VAG cars for professionally. The only way to get any kind of good result is wallnut blasting etc. mechanical cleaning. These HHO etc. voodoo machines do nothing, as you can see for your self. I have dynoed several cars and with proper cleaning the gain is about 10%. Also injector check with proper ASNU tool is essential, since specially 1.4tsi injectors are crap, they wear out low as 100k km´s and need a replace.
I'm editing the walnut blast video now, should be on UA-cam by Monday. However my 1.4 TSI has done 247,000 km and the injectors are still fine. Now I've said that they will probably fail next time I use the car 😂
@@ConquerDriving are the injectors been checked on injector dyno/tester? Not saying that they are faulty but you would be amazed how much there is fluctuation in the amount what they spray on the test.
No, they haven't been checked.
VERY interesting! NOW what you need to do is remove the head and ONLY CLEAN THE CARBON! Do NOT grind the valves or make ANY other changes and record the difference.
The reason I'm asking IS, ECONOMY. In other words, does cleaning the valves result in increased fuel economy, and if so how much? Would the increase in fuel mileage make up for even PART of the cost of manually removing the carbon over time?
Inquiring minds want to know!
Surely adding oxygen into the mix will just change the air fuel ratio measured by the O2 sensor? Ecu will add more fuel, lowering the deflageration temperature at specific load capacity.
Secondly, adding hydrogen, increases predetonation, engine knock sensor will reduce fuel into air charge and retard timing, so all the hot gases are leaving the piston cylinder early, again, reducing deflaguration potential.
I cannot see how any of this works.
The best result I had was running propane directly into air box and a methanol injector running water mist into the inlet plenum. This internally steam cleaned the inlet manifold during use, at high charge consumption. Propane reduced fuel air ratio , engine ran rich and ecu did not compensate. Result, hotter more complete burn, more energy per deflaguration cycle and entropy from the water mist. Best engine clean I ever had.
That's interesting. I did a walnut blast which worked very well.
Hi ! Grate video.
Did you try any other method for cleaning the vaulves ?
Yes, a walnut blast worked well:
ua-cam.com/video/fgvNu_HVD_g/v-deo.html
@@ConquerDriving thank !
A good video Richard. However Terraclean works a huge amount better.
Thanks Harry, I'll check them out.
I thought the Terraclean system uses the cars fuel injection system to introduce the cleaner into the engine. So Terraclean wouldn't clean the inlet valves, in a direct injection engine.
I believe they have a system that pumps a chemical through the inlet manifold.
There are fuel additive fuel system cleaners available for around £10+ that do a far better job than terrorclean.
Also, hydrogen carbon clean treatments are chemical free 😉
@@Chopperdod77 fuel additives can't help clean the intake valves on a gdi engine. I believe Terraclean pumps a chemical through the intake manifold to clean the valves. I've tried a chemical though in another video and it didn't work.
did u use tesco petrol???
Petrol makes no difference to the back of intakes valves on a GDI engine as it doesn't come into contact with it.
Okay so it works but if only the before after pictures were better, maybe it would be much more convincing.
Hmm interesting, I think you saved me a bit of money. I'm thinking of using a steamer to have the steam go into the engine as i rev. I live in a small third world country. I've literally checked every mechanic on the island. No one knows how to carbon clean.
Be careful not to add too much steam, the water may condense in your intake and hydraulically lock your engine which would be game over.
@@ConquerDriving thanks man. I'm aware of the possibility of hydro locking. But I'm willing to take the risk.
@@DeepThinker193 p
Hydrogen and oxygen... basically water 😂
legend
Hi excellent video! I can’t find the part 2 of carbon cleaning, what worked?
Thank you. ua-cam.com/video/fgvNu_HVD_g/v-deo.html
@@ConquerDriving fantastic thanks and an excellent video 🙌🏽
With som much deposits it’s not that easy to remove them but I still wonder if it has any effect whatsoever. Normally if it worked and you did this every year to keep the valves clean it would be very nice
The cost to do it every 10k miles (£40 each time) I may as well pay for a walnut blast every 50-60k miles as I know this works for sure now.
The real test is to see how much use you get out of seat before u start having the same issue , if it never comes back then money well spent
I guess it will be back in 4 months or so.
@@ConquerDriving How are your results now?
@@KarmaPolice93 check out my video on Walnut Blasting.
would like to see a picture down the spark plug holes of the piston.
I didn't get a photo but I could see that it was very clean, only a thin smooth layer of black if I remember correctly.
I am happy with my I-miev. Never any carbon in any parts :D
😂 I think that is the future. Although they're getting on now, must be at least 10 years old.
@@ConquerDriving Mine is the Peugeot one. ts 5 years old. Only does about a 100km on a charge. Maybe too low for a school car. But for my use, its ideal. Very quiet too :D
Good video. Best method is... ?
Walnut blasting was what worked for me.
it's a total con, we had 6 cars done one afternoon, 1 car had 3 treatments and it made absolutely no difference at all to the inlet valves which the guy was adamant that they would be clean, let's say he drove away with his tail between his legs rather sheepishly and didn't last long in business. why people waste time and money using this service is beyond me.
This is what happens to direct injection engines that Volkswagen use in their cars
Did your car suffer with engine management light before the clean?
Yes, regularly. Still did after the hydrogen clean. Walnut blast sorted the problem.
Have you had this walnut blasting done at all
What was the cause or reason for the check engine light?
Super
Great video.
You look like Niki Lauda BTW
Haha, I would say he is a bit different.
Buy an intake and valve cleaner like CRC that has PEA in it
I did a video on that, didn't work.
Use cleaner fuels,propane/natural gas.How many miles a day do you do,electrics cars now do 200 miles on a charge.Over all you could reduce your costs !
Fuel doesn't make a difference to intake ports on a direct injection engine. Also, my car is mostly used for teaching people to drive manual.
Repeat the carbon clean over a period of months of as one clean is not enough
Hi, why you didnt check exhaust valves?
They're not a problem and this video is about intakes valves. Watch my video on walnut shell blasting for the way I sorted the problem.
Try walnut shell blasting! 100% works
I did: ua-cam.com/video/fgvNu_HVD_g/v-deo.html
Did the vehicle have the VAG emission cheat software?
Ahh petrol...
No, it's petrol.
Mr oven! That's what i did
Is that Freddie Mercury ? 😉
I can try to pretend to be. 😉
Can I ask, is it 2 parts hydrogen to 1 part oxygen mix .. Dihydrogen monoxide... HHO or ... H2O or...... Water ???
About half and half when you consider the air has oxygen. But water is 2 hydrogen for every oxygen. They use ordinary water.
Its O2 and H2. HHO is not a scientific name
@@sidescrollin H2O is the chemical formula for a water molecule, where a single oxygen atom is bonded with two hydrogen atoms. HHO is a popular way of writing OxyHydrogen - a mixture of hydrogen and oxygen gases, usually in a 2:1 ratio. Thus, HHO = Hydrogen-Hydrogen-Oxygen. Since the oxygen and hydrogen are in mixed gas mode and not bonded, it is not H2O (water). Bonding hydrogen and oxygen requires an ignition and chemical reaction. When the Oxyhydrogen gas is lighted, oxygen and hydrogen atoms bonds and releases energy, the end result of the chemical reaction is water vapor."
So carbon cleaning doesn't work and good way of proving it in this video.
What you need is the inlet walnut blasted.
I did that in a later video. Worked a treat.
Thanks for this. It's a total scam...
You should asked the guy how mutch liters a minute of hydrogen he pumps true your engine. This cheap guys mostly pump 3 to 10 liters. I just did my ibiza 1.2 tdi with 220k km. Pumped 38 liter hydrogen p/minute. And the valves egr everything is super clean. You just got ripped off bro😅
This is false. You are talking nonsense.
Can you test HHO generator
I'll put some thought into that. If it worked I would have thought a manufacturer would have implemented it by now as I believe they have experimented with it. But in theory it should work and improve efficiency. I believe they only need about 75 Watts of power to work which isn't bad.
@@Chopperdod77 I'll look into that.
Having looked into it a HHO generator may clean the engine of carbon slightly but would cost you a small amount efficiency overall so not a good move if you want economy.
@@ConquerDriving
The Atmos-Clear kits can give a return on fuel efficiency up to and above 20%.
It improves efficiency.
It's hard to see exactly what atmos clear is actually offering. But if it's a HHO generator run off a cars alternator this type of device will not improve efficiency. I can't comment on how it would affect emissions but it can't improve efficiency as it would violate the first rule of thermodynamics. Also common sense tells me if it worked every engine manufacturer would be using it. The term I think people use is snake oil. However having searched their website I can not see what their device actually does which leads me not to trust them.
walnut blast is the answer...
Yes, I did a video on this: ua-cam.com/video/fgvNu_HVD_g/v-deo.html

A hydrogen carbon clean can't clean the intake. Nothing is burning there...
soooooo GBP99 down the drain! LOL
is Seafoam good?
I've not tried it but I doubt it would be much different.
No its snake oil.
Haha amazing
it don't not give improvement because machine relaid on the H2 and O2 only but it should be mix with cleaning agent solution, which contains of Cationic for removing the carbon
I do carbon cleaning and 45minuites isnt enough for this mileage. Anything over 100k wants at least 1hour to burn the carbon off more efficiently also using and intake and egr cleaner like i would suggest would clear the intake more efficiently and remove the oily deposits. Cars with direct injection will benifit more with the intake cleaner.
What wrong with youre emotions? Damn you look scary while you talking bro 😂
Have you looked in to walnut blaating
That's my next step
had my rs4 carbon cleaned.
felt like a different car
Cleaning with hydrogen and oxygen? This creates an enormous explosion risk, it is already dangerous with hydrogen alone, which is the most explosive gas that exists.
The carbon on the intake valves should burn on the stem side? Fire should never start on that side. If there is no fire, hydrogen will not remove the carbon at inlet temperatures. What gas did that man blow in? Probably just air. Then a test on a power bank? Surely this man knows that you have to enter the temperature, air pressure and water vapor voltage in the computer of that power bank? This has to be done with the first and the last test, that has a considerable effect on the outcome. He doesn't even seem to be doing a comparison test based on his comments. He must be able to indicate the power compared to the first measurement conditions, then you know what the real difference in power is. Usually the computer measures this data itself, but it does not appear from his comment that he knows this. In short, 2 buggers in a row.
£33 per hp gain, bargain…….. 😳
The biggest con in the motor industry!
Nice to meet you, Conquer Driving, I would love this video and information, can you give me your email, I have some question. Regard.
I used a wallpaper steamer strate into the inlet 20l steam latervwith engine running at idle now runs very smooth check out my page
I have heard others using steam. Won't help your intake valves though.
The hot steam entering the intake passes over the carbon on the intake valves.i think you will find it far more effective than hydrogen gas i have lost my bore scope footage but it works a treat i now get between 5 and 10 mpg more
Just stumbled across this as these machines are cropping up everywhere - if you want the job done properly take a look here. balancemotorworks.co.uk/carbon-cleaning-with-walnut-shells/
