Never heard of this before. What's OOFs thoughts?

[Bigron]

On an allied topic, does anyone use Redex UCL any more? And did it ever work?

Ron.

periodical cleaning on a low mileage new-ish engine  ok.. high mileage engines =trouble

[Field Marshal Dr. Opti]

I regularly used to 'decoke' my 2 stroke motorcycles.

I would take the carbon from the top of the piston and the exhaust port with a 2p piece.

After pulling out the baffles, I would use caustic soda in the exhaust with a potato shoved at one end to stop it coming out. The spannies got very hot.

Water?

No! Just....      No!

[Sir Tigger KC]

It was a very basic old lump he uses in the demo, that you could probably pour tar in and it'd still go! 

A modern engine? No way!!

[Nick W]

A modern engine shouldn't need decarbonising anyway. Fuel injection, mapped ignition, modern oils, tighter machining etc all make it much less of a problem.

What he said. Carbon buildup is a myth these days. It doesn't happen.

What a load of old tosh...by the look on his face he was not sure if the engine was going to cut out and afterwards he had only used the water down to the first rim on the beaker...i bet he drank the rest...utter rubbish and not needed what so ever.

[Webby the Bear]

Yeah I was watching it thinking 

Obviously steam cleaning does work on things like drive ways lol but how is a bunch of water going to help? The temps in the engine are very high anyway so would have thought there wouldn't be any build up anyway 

[Vamps]

Yep, in the good old days you needed to de-coke regularly, now you seem to just have to change a cam belt, and they call this progress.............

[Andy B]

When the head gasket on my 24 valve Senator failed & let water/coolant into No 6 piston, that piston crown was sparkling clean! 

[Vamps]

On an allied topic, does anyone use Redex UCL any more? And did it ever work?

Ron.

Used to do just that, years ago with Redex, take the air filter off and pour into the carb air intake slowly, the smoke and crap that would come out................

[zirk]

For that to work, in theory, the water needs to vaporise into steam, so we talking about 100+ C degrees, no way is it going to reach them temperatures on the inlet side side of the intake, might get there when in the combustion chambers which might help if your looking at rusting the inside of your exhaust system a bit quicker.

Might be a bit more convincing if the guy was to inject steam into the intake, but still not convinced, so its a no in my book.

Also guessing the guy is pouring water into a Carb system, they do tend to suffer more carbon build on the intake system side, rather than fuel injection which just builds up the crap it sucks in and more to the point the oil fumes from the eco designed crank case pressure release.

obviously with an lpg-ed car you have to wait very very long   (may be never in this life time)
