conbustion chamber cleaning via spark plug hole

[jagman21]

just wondering whether this is possible during a service while changing the spark plugs.

My guess would be to mix a high concentration of engine flush with engine oil, and inject it with a syringe into the chamber while the spark plugs are out, then run engine and flush out the old oil.

Would this hold an advantage over the tradional method of flushing an engine? Would this just "flood" the engine with oil/flush? cause excessive wear?

Would the car even start afterwards?
PS I'm not gonna try this but it was just an idea.

The best way to remove carbon from an engine non-invasively is to add water to the intake as a mist. Ever seen how shiny cylinders affected by a blown headgasket are? Quite small amounts of water added over a few miles running on a hot engine actively break-down carbon deposits- it goes out the exhaust as CO / C02.

Why exactly would you want to do this ?

If you drive a bit harder occasionally the cylinders will clean themselves to some extent unless you have oiling issues. I certainly wouldn't attempt to clean a cylinder with the head in place. Think of all the crap that'll get into the ring lands.
