Still amazes me when you see people that have had it done by many of these companies and men in a van saying they can feel a difference after. I had a proper intake off carbon clean on my 8p RS3 years ago when I was getting 5 new injectors and couldn’t feel a noticeable difference 😂 My main argument is that if these snake oil treatments worked so well then why don’t these companies do before an after comparisons? Probably because they would get called to task by advertising standards.
It’s why a port injection engine will always be better for longevity. A truly great video, so get your carbon cleaned and just buy new injectors all round.
Ur understanding and ability to share at dumdass level i.e. me , is so cool i a,m always learning ans am amazed at ur level of mechanical engineering, thank you Thank you for helping our youth learn how work can b fun and incredible intricute wow always looking forward to ur next vids. Heres to the latest version of Squirel Piss lol
Really informative video and excellent detailed explanation. I’ve seen mobile carbon cleaning services which look attractive for bog standard family diesel, but they still put additives in your fuel tank. I’m guessing anything that is going into the fuel tank other than fuel is basically a massive red flag?
Isn’t injector cleaning different from de carbonising the back of the inlet valves. Can you tell me if my 2006 Aston V8 Vantage is GDI or port injection and if GDI is it worth fitting an oil catch can so the oil mist doesn’t go into the inlet
Poor mans carbon clean. Cut off the ends of a load of cable ties, all different lengths and rough cut, bundle em up. Put em in a drill , get a hoover , wizz em down your intakes, cheaper than walnuts.
I absolutely love this video watched a few times as I’ve thought about terraclean after seeing it used on wheeler dealers. Could you give your thoughts on redex for petrol cars is it worth it. I always run my cars on momentum 99 does redex do anything. Love the content
Had an engineer who was working 150 miles away get a stone chip on his screen. Found a one man band who could repair it for £60 , which was a bargain as Autoglass wanted over £200 !! . He called me when it was done and said, while he was there, he could do an 'engine clean' on the van. Said it would pay for itself with fuel savings and this and that........... ended up as la la la in my head. Can't remember what he was going to charge me as I said no straight away, paid the screen repair and off he went. My old man, when I was a kid, did the same theory on his MGB with a bottle of Redex. That decoked the engine , allegedly. We went for a drive after it soaked in overnight and it looked like an almighty fog suddenly appeared behind us for at least 10 to 15 miles of plumes , like I had never seen. It may have caused accidents, I would never have seen it. Did it work ? No idea. We started with a gutless 85 bhp in a lot of pig iron B series engine and ended up pretty much the same, so guess not.🤣
There is a little more to the story. To eliminate the carbon build-up problem in GDI engines. some car makers such as Hyundai and perhaps Honda took a cheap fix - they reprogrammed the car computer to pump extra rich air-fuel mixture at cold starts for several minutes. Result is, some of the gasoline doesn't burn and it's coating the combustion chamber = the intake valves now stay clean. However, as with any cheap solution come ugly-side effects. Some of that unburnt gasoline leaks past the pistons and dilutes the engine oil. Results : kaboom Hyundai engines and severe cam damage on Honda engines.
Brilliant video as always, one really basic question if you don't mind, what's the best way of prolonging the life of an EGR and DPF🤔 so many different answers, thanks in advance......👍👍👍👍
I've seen A LOT of cleaners for direct injection cars that are introduced on the intake side to clean the back of the valves. No amount of fuel additive is going to clean a valve when it will never see the back of the valve. I think most of these cleaners are just toluline, so on a chemical level, it should work.
What injectors do you replace with Ricky? Early facelift V10 here. Going just over 30K miles and am going to do plugs, fuel/air filters. Thinking of doing injectors and coils at the same time as preventative maintenance (all oem?). Thank you Sir!
Around 30 years ago I put snake oil in my 86 Corolla carburetor and it blew up the exhaust foiled the plugs have not tried one since. I don't think it's going work better as Squirrel piss or Wonder urine or whatever they call it.
Excellently explained. it's pure marketing bull to sell snake oil. extra bonus if they mention their product being ecofriendly, biodegradable, fair-trade, etc
I use to work as a insurance broker and te amount of engines that blow insurance know some policies don't even cover anything if you have a carbon clean. I had multiple claims from vans to super saloons, it never empties out the engine and coats the engine, so when you use if your car survives it's heavy internal damage.
I don’t know who they would tell if we had done an inlet system carbon clean via walnut shell? I can’t see how it would cause failure either. I understand the point with the “terrible clean” style systems.
Is it not also the point that in a direct injection engine, the magic potion passing through the injectors is downstream of the carbon buildup on the backs of the inlet valves? It cannot do anything about that.
I made a mistake a few years ago, bought my wife a new car with .DPF filters did my research afterwards 🤦 and sold it within nine months and just took the hit. No bloody way was I going to drive a car with technology that is based on sticking an oily rag up the exhaust to collect deposits and live with the long term implications. Modern cars have just got worse and worse as they address EU emissions.
I also notice Mike Brewer has popped up in the classic car press in big full page ads plugging those cans you plug into your fuel line to allegedly boost octane levels. How are they getting away with this?
Was he talking about GDI engines? You can benefit from injector cleaner in itself, but if you're running GDI it will do absolutely nothing to help carbon buildup.
I agree with everything, except (and it's not only you guys) when people say 're-burn exhaust gas', exhaust gas is inert, it can't be burned again. It's primary function is to be reintroduced to aid in bringing down NOx emissions. This is done twofold by reducing the available space in the combustion chamber for combustion to take place and allowing some of the temperature of combustion to be absorbed by the exhaust gas thereby reducing peak cylinder temperatures, in turn reducing the formation of NOx as it is high combustion temperature that increases NOx formation. Just a pet peeve of mine 🤣
So you are the 1 person in the 4500 views so far who would have differentiated between my 1 line and the paragraph you wrote! Lol If I laid the scientific process down to everything all the viewers would be asleep! 😂😂 I agree with what you say, but remember in an Otto engine the exhaust gases still carry HC which is unburnt fuel, as combustion always occurs below lambda 1 so there has to be unburnt fuel molecules! 😉
Haha sorry, I was just being pedantic. I didn't mean it as a derogatory comment in the slightest. This is very true, I guess you do have to balance it out, maybe EGR could be a video unto itself? Aha. Would that not be insignificant in theory? How far below lambda 1 would combustion occur because under light load cruise conditions is the fuelling strategy to aim for stoic? Obviously it's never bang on because you only know what's happened in the combustion chamber after combustion as the sensors are downstream but wouldn't that mean in theory the burn is ever so slightly rich, then lean? Is it ever ideal? I'm not being an arse here, this is a genuine question and why you guys do this job and not me. I'm always up for being educated and will happily take it on the chin if I'm wrong. I know this was not the topic of the video so my bad for spamming the comments aha. What I said earlier was what I was taught about EGR a long time ago now.
@@AB-gt5sl Wasn't taken badly at all mate! It is emissions based control as we true and tune it out completely a it messes up accel and decel enrichment/enleanment for dynamic throttle movement. But yes, in theory when you move to a closed throttle position an then small opening afterwards that's when EGR would be engaged to try and help tidy up the exhaust gases after being under load. It is reactive as if you are under heavy load for long periods it doesn't do anything. Cruising i would expect lambda to be between .98 and lambda 1 depending on car and age etc.
100% agree! I'm going to do a real carbon cleaning (removing the intake manifold) on my gen 1 v10, how much hp do they normaly gain after the cleaning? My stage 3 vw gli feels faster or about the same then my v10 r8 lol
Thank you for this year’s ago I had problems after injectors was cleaned and I was told I was wrong I put new injectors in car was mint keep the videos coming 👌👌👌👌
This is the most clear and concise advice that is non letigious and well thought out. I listen intently to your advice and respect it dearly.
Thank you!
brill video nice to hear a clear explanation of what's good and what is not,
Thank you
A nice little Science vid for a Monday cheers Ricky

What is your opinion on engine flush additives?
Don't buy squirrel piss...... 😂😂😂
💪🏼💪🏼
Well put the general population do not understand how an internal combustion engine works.
Very interesting…what shocked me was I actually understood it..& that’s a very good test for a good explanation with my mechanical knowledge 👍😂
Hahahaha

Yeah it’s snake oil in my opinion!!
Are you describing what a certain TV mechanic did using a so called purified gasoline in a couple of cans introduced into the fuel rail via a machine?
Yes sir!!

To eliminate the carbon build-up problem in GDI engines. some car makers such as Hyundai and perhaps Honda took a cheap fix - they reprogrammed the car computer to pump extra rich air-fuel mixture at cold starts for several minutes.

It's not the combustion chamber side of the valve that needs cleaning. It's the other side which doesn't benefit from your described intervention.
Brilliant video as always, one really basic question if you don't mind, what's the best way of prolonging the life of an EGR and DPF🤔 so many different answers, thanks in advance......👍👍👍👍
proper maintenance,good quality fuel and oil and minimal short journeys
Interesting subject, but I initially avoided the video because of the silly Clickbait title.
I’ll help you out too, Terraclean is snake oil!
It’s only a title! 👍🏼
Outstanding video! Well done 👍 Ricky for PM!! Most sense I’ve heard in a long time
Thank you!

So much money to be made in snake oil still, cheers from OZ.

I think this is a very well reasoned and well Explained argument against this so called cleaning process. Notice I didn’t say “Product” Rick lol

Exactly that!!
Great explanation👏🏻👏🏻👏🏻👏🏻. I’m in the trade and this also grates with me. Don’t get me started on DPF cleaning 🤣🤣🤣🤣
I know lol

Could not agree more 👍👍 however it could work on your average 1973 Austin Maxi HL 😀
Not many of those on the road! Lol
Lol. Thanks, im now fondly remembering the old 1974 Austin Maxi my dad drove. Bright orange land crab.
Direct and backing up with pure facts ..educational
Thanks!
You're not talking about redex here???
No terrible clean!
is you camera broken the colours are off
you look GREY ??
No don’t think so! Looks fine on my screen!
@@REPerformanceUK
Maybe It's the color filter?
This hits the nail on the head ,,, well done , great video.
Thank you!
100 percent agree with you!

Squirrel piss 😁
Glad you liked that!
Brilliant explanation 👏.
Cheers Mark! 👍🏼

I have no idea if true but I hear walnut shell blasting will embed fragments in aluminium. I believe some other media is preferred? Dry ice etc.
