Years ago when I worked in a dealership we used a fluid to burn the carbon from the combustion chambers. The mechanic would take the car out into the country, then hook up a line from the can to a vacuum port on the intake side, and go for a little run. The smoke would just billow out until the can ran dry. It apparently did a good job. Does anyone recall this product that I can use to burn some carbon out?

I've seen it done with plain 'ol water poured out of a Coca-Cola Bottle into the carb while keeping the rev's up. (by a mechanic at a Arco station I worked at as a kid...) (IMG:style_emoticons/default/ohmy.gif)

I have used coca cola to do it before....
I have even had some low power Turbine engines like a 2liter of coke ran through them..... The deposits just pour out of the exhaust flange. |

He is right about the Coca Cola....I believe it works because of the acid in the coke.
I am a nurse and we use coke to clean out G tubes...same concept though...just using it on people instead of cars in my line of work..... (IMG:style_emoticons/default/smile.gif) |

Using orange Kool-aid to clean the toilets onboard ship was the most amazing one I have seen! Cleaning a pisser that sees 1000 people a day is a true chalenge for anything... Kool aid is the best! Just ask any Squid and they'll say the same thing!

Swepco has a product and the instructions are very much the same as you describe. I think it's the Valve Cleaner additive.

So has anyone done this...or have they just heard of doing it (aside from Jake)? And does it really work? Might help a tired old car/bike work a little better. My bike had a ton of buildup in the header when I repainted it (IMG:style_emoticons/default/blink.gif)

Coke should add an addendum to their label for instructions...

Whatever wonder concoction you guys put down your intakes make sure it's in small enough quantity that you don't get a hydraulic lock and bust the motor. I'ts probably easier than it sounds (to lock & bust the motor). I would replace the word "pour" with "mist" in all of the above. I have seen a motor get hydraulic locked on a surprisingly small volume of fluid.

I think Coke would be a VERY bad idea.
Ever have some smartass dump sugar in your gas tank? Know how much sugar there is in Coke? Maybe diet coke. . . Or better still, a fluid specifically made for the task. |
