Anyone see the episode, where he de-coked the engine and exhaust system with that machine? for £70 i thought that was great, cleans the cat as well, injectors, everything, all the emissions were rock bottom.... new technology apparently, was wondering if this can be done on a diesel as well?

The machine was a fuel decarbonizer, ( the car was a Jaguar XK8) before he cleaned it out it was 0.69 %vol CO and 533ppm vol HC, and after 0.56 %vol CO and 79 ppm vol HC and it cleans the cat and the oxygen sensor as well, I cant find the clip but found this, Terraclean Fuel and Post Combustion Decarbonizer - YouTube, its new technology apparently, and will cost about £70 for the clean, well worth it if it duz what it clams to do,

sounds like bollocks ,modern engines dont need decokes ,plus if your enviromentally minded carbon is best in solid form not gas
If i was environmentally minded I wouldn't drive a Range Rover
I would buy some ****e Jap Inbred hybrid

Looks like snake oil to me. Watched the video all they are doing is introducing something into the engine to increase the temperature of the combustion/exhaust gas dramatically so as to burn off deposites. Modern fuels don't make a lot of hard carbon deposits, they make soft ones which are flushed naturally by the running the engine in the most part. That is why you don't need a decoke every 30,000 miles anymore.

Octane rating increases the point at which fuel can be compression ignited. If that was the case i would rather spend a quid on some moth balls and throw them in the tank, than £70.00 on their treatment. The moth balls would give just the same effect.

Yep saw that, looked impressive but was wondering what those two chemicals did to the lubrication of the engine whilst it cleaned itself for an hour (don't know if a Range Rover engine would run for an hour before overheating?00 was it washing the bores etc and adding wear to the engine?
When cleaning injectors we use ultrasonic cleaning to remove deposite that don't normally wash away with a fluid?/ interesting?

Hi Dopey, I've just watched the xk8 wheeler Dealer . Thought the de coke looked a great idea! It certainly seemed to make a huge difference to the Hydro carbon reading. Enjoyed the whole programme to be honest. I appreciate that there is some fantasy involved in the show, but it doesn't stop it being good to watch.
Did see it, thought Hmmm. Don't know about diesels, cos it did ,as was said in this post, bang in some really high octane fuel to burn the s*** off. It seems a fair enough thing to do on a high mileage V8, cos that is a "dirty" engine (take a lambda sensor out and see how much deposits are on it) and it's got to be better than taking apart an otherwise ok engine. But couldn't you get stuff called "redex" that does the same, admittedly with a bloody big cloud of smoke?

I seriously doubt it is high octane fuel that is used to clean the system. If you watch the video the guy explains that it is the high octane part of the fuel that causes hard carbon build up. Whatever the two cans contain must be some thing that increases the combustion temperature to burn off the deposits, something like oxygen and acetone mix would do that. Octane rating is much misunderstood it is about when the fuel burns and not how the fuel burns.

I used to pour brake fluid directly into the carb on the series111 to de coke em you aint seen smoke like it but it did the trick:rofl::rofl:

I've had some really good results with Terraclean,esp when I fit a Hiclone at the same time....

:hysterically_laughi:hysterically_laughi That about sums it up.
Many moons ago an elderly man showed me a trick with carbonated water i.e. sparkling water, shake and with engine running some revs he spayed it into inlet, sputtered a bit and i thought it was mad but then he showed me the spark-plugs there was quite clean and claiming it cleaned many parts in the combustion system.
I've until now had new cars only so never tried it but the P38 may have a drink:scratching_chin:
Anyone ever heard of that? And is there potential danger of damage?

Any sort of water sprayed into the engine will do the same thing. Water was injected into aircraft piston engines for years to give extra power. Also into the tailpipe of jet engines for more thrust. Try spraying water on your chip pan if it's on fire. See what happens.

Makes perfect sense,if you inspect the combustion chamber of and engine that has been running with a blown head gasket and eating coolant,you will see how its been effectively steam cleaned.But with a modern engine carbon deposits are really not a problem - even on engines well over 150 k.
And as for passing emissions tests,thats just a joke,as an example I've just finished replacing a 4.0 v8 Gems engine into a Bosch managed car with all the problems etc in doing it.The engine was a tired old banger with a well streched timing chain and plenty of brown gunge inside the roker covers etc.When I MOT'd it the Co was about 0.08, the Hc's were down to about 15ppm.And i didnt even put new plugs in it,the cats and oxy sensors looked like the originals with 106k on them.Any modern car running properly does not need ANY help AT ALL in passing an emissions test,its just snake oil.
