Fuel system decarboniser

So I saw on Wheeler Dealers today that Edd China used a a machine called a fuel system decarboniser on a Jag xk8 that helps clean the engine and bring back performance.
Has anybody done this on their car before and what are your views and opinions on it.
Is there a machine for diesels also?.

I will be able to tell you in January how well the Terraclean works as well as three other competitor products for this type off flushing.
In regard to the intake system no chemical treatment can restore the intake track to new as the carbon build up is too thick on diesels to be removed completely. Abrasive blasting is the only cleaning method that will make the intake tract squeaky clean.
Stay tuned for a new sponsor who will be offering cleaning services.

Saw the same episode Dopi, thought about it a while back but forgot about it. Would like to hear what you have to say about it George, what your findings are.

I'm sure some of us would be keen on this service.

I have an engine in pieces right now and just had to clean carbon off everything.

let's see..... I used a drill, steel brushes, sandpaper, a razor blade, a variety of files, a pot scourer and a Dremel tool.. and it's STILL not all off.

I would love to see any chemical that can remove carbon.

Only thing I know of that does work is water injected during combustion which then becomes a supercritical solvent. Air force pilots used to use this to clean carbon out of their fighter engines in WW2

This product is the answer to a problem that really doesn`t exist....today`s top-quality gasolines have a whole list of additives designed specifically to keep your fuel system clean and in proper operating order. Good-quality fuel, combined with a bottle of Techron once or twice a year is all you really need.

I saw this as well. Also interested to hear if it works.

There is no chemical that can clean the carbon completely without destroying aluminum components.
The only way to get it squeaky clean is to blast it with a abrasive such as walnut shell.
Water injection on a normal car uses too little water to make any difference to the carbon build up. If you take the amount of water a CM10 which is a very large jet for turbo cars sprays its not enough to even dent the carbon.
Will be posting up some useful info in the next few days with a years worth of testing and findings.

The new fuels will keep the fuel systems clean. Carbon will still build up on the piston due to lean run on cars. The intakes still get clogged due to carbon build up cause by EGR and the DI system. Google is your friend. Search carbon build up on direct injection cars.

Will water injection not erode carbon over time?

It makes no difference at all. The amount of methanol that is sprayed over the four or six cylinders has zero affect.

Here is a picture of a Golf Gti running methanol for the past 40,000km. The engine is sitting on 90,000km and it seems the methanol has made zero difference.

These are also my findings with my 335 which has run 100% methanol for 3/4 of the mileage it has done. Will post up some boroscope pictures of the side view of the valves and the carbon is close to coming over the valve causing sealing problems.

The MK7 GTI motor is now being released with secondary injectors. These will be for cleaning purposes only and it will be interesting to see where in the engine cycle they are active and over what period and what cc they are.

damn i though WM would somewhat minimize this... Im guessing a catch can and WM will go a long way to help but a clean will probably be needed every now and then anyway...

Unless you can soak the whole engine for weeks, I can not see how chemicals will clean it completely. George is right, blasting is the easiest by far, even considering the striping of parts, and the results are good. But it will cost more than n can of magic monkey's carbon mousse.
