Engine carbon Clean - snake oil?

Mini cooper s engines from 08 to 2012 certainly need it, inlet valves get very clogged up and cause running issue's, many more petrol direct injection engine's of modern manufacture suffer the same.
The standard Terraclean snake-oil is pumped through the fuel system, so it won't get anywhere near the backs of the valves on a direct injection engine.Mr2Mike said:

If you do a quick google image search for terraclean Rs4 you will see they inject it into the inlet after the airbox and before the throttle body on engines with direct injection. I'm looking at the Terraclean website and I can't seem to find a before and after picture of the inlet of a gunked up direct injection engine, taken by an independent testing body. Probably just an oversight, as I'm sure that many thousands of miles of carbon build up will be easily removed within a few minutes of using this system.

Ah this is what I was wondering about.So if it does dislodge the half pound of soot blocking up the inlet manifold and the intake ports, it blows it all the way through the combustion chamber, through the exhaust ports, through the EGR valve and compressor, the particulate filter and the catalytic converter. Sounds like a good idea

I understand the basic principles behind de-coking although,in my limited experience, engines seem a helluva lot cleaner these days than 20+ years ago. For example engine oil seems to stay clean/amber for weeks after a change (rather than minutes). It was some of the odder claims that ECC are making that made me think it was a scam.
One was the use of hydrogen gas. If somebody could explain how this gets rid of carbon deposits I'd love to know. Another of their claims is that it gets rid of the carbon from inside fuel injectors - how on earth is there a build up of carbon inside those?

BMW/MINI and a lot of independent now offer crushed walnut shell decoking. Walnut shells are blasted at the coking and it is hard enough to remove it and not damage the valves. The crud and shells are vacuumed out and doesn't need the head removing. Cost c.£300.
People used to use walnut shells to clean jet engines, maybe some still do!I've looked at a couple of videos as I couldn't see how they would do it without removing the head - it seems that they only do the intake valves & ports on the direct injection engines as they suffer build up of carbon (from crankcase oil) due to the absence of fuel wash.

I seem to recall something like this was done on Wheeler Dealers and there was a bhp improvement?
Yes, that was Terraclean. Edd has been known to feature in their advertising! And, coincidentally I'm sure, the service is offered at his establishment in Bracknell.Old thread but some value added here. This US product appears to remove piston carbon deposits:

Is petrol in the US more prone to carbon build up? Their oil tends to be a different mix.

OxyHydrogen or (HHO) can and does clean the carbon out of the combustion chambers and any engine part where the combustion happens. It does it by raising the temperature when the fuel ignites hot enough to blitz the carbon but not so hot as to melt the engine parts. It's not a reaction (it does not combine with the carbon) but it does atomise the carbon so it passes safely through the exhaust system with no carbon clumping. It's use as an engine cleaner was discovered in Canada when it was being trialled as an emission free fuel. It failed as a fuel but the scientists noticed the engines they were using were cleaner following the tests. I get my engine done when I take it in for servicing and do notice a difference.

Oxyhydrogen? That stuffs dangerous - people die if they try to breath it.

t merchant. Call it water you plonker. And it failed as a fuel? No st sherlock"Oxyhydrogen is a mixture of hydrogen (H2) and oxygen (O2) gases. This gaseous mixture is used for torches to process refractory materials and was the first gaseous mixture used for welding. Theoretically, a ratio of 2:1 hydrogen : oxygen is enough to achieve maximum efficiency; in practice a ratio 4:1 or 5:1 is needed to avoid an oxidizing flame.
This mixture may also be referred to as Knallgas (Scandinavian and German Knallgas: "bang-gas"), although some authors define knallgas to be a generic term for the mixture of fuel with the precise amount of oxygen required for complete combustion, thus 2:1 oxyhydrogen would be called "hydrogen-knallgas".
The term Brown's gas refers to oxyhydrogen with a 2:1 molar ratio of H2 and O2 gases, the same proportion as in water. It was named after its Bulgarian inventor Yull Brown (born Iliya Valkov, Bulgarian: Илия Георгиев Вълков), who suggested it to be produced by the electrolysis of water to be used as a fuel for the internal combustion engine. Later "Brown's gas" and HHO has become fringe science terms for a 2:1 mixture of oxyhydrogen obtained under certain special conditions; its proponents claim that it has special properties."
Still laughing???
Must admit... I've found myself looking at such posts / claims / services and wondering if it'd do anything on her slightly well worn old diesel Volvo and got to the stage that having changed the filters the the oil a couple of times, such a service may be the thing to help it clear it's lungs and run better.
Then I was in a breakers and found a similar engine'd V50, in pieces and the inlet tract was lying to the side... had a look and noted the good 3mm crust of oil, black crud coating everything so had a poke at it. Some was baked solid, some was like a sort of unpleasant Nutella consistency... it never did come off my jeans and took about three days to come off my hands.
Anyways, it was at that point that I figured that if 30mins of pumping gas in to the inlet in exchange for £100 pounds was able to clear all that crap from the internals of an engine, it'd be the best bargain this year. Then I decided that the chances of that happening would be a miracle and thus, to me it's a bit pointless and the only real way to clean out a diesel of this st is to start dismantling and be prepared for a horrible job ahead.
