Can someone who has used "Seafoam", tell me is it as good as they claim, and is there any downside to using it. Thanks. /ubbthreads/images/graemlins/confused.gif
 
Works pretty good, your car will smoke for a few minutes until it's all gone, but other than that... no ill effects that I've ever had.
 
"Car Talk" endorses the do-it-yourself water treatment to get rid of combustion chamber carbon. Per the article in the May 26 Seattle PI, run the car about 1500-2000 RPM and drizzle several ounces of water directly into the carb throat.

I suppose with side-drafts, spraying it would work as well.

I have used this several years ago with good success and no damage. Of course if you DUMP a pint of water in you could (and probably would) liquid-lock a cylinder or two. Not good for the engine.

This is the method my father used to de-coke engines when I was a kid; all manner or crud came spewing out the tailpipe, which I found most amusing as a 6yr old. /ubbthreads/images/graemlins/tongue.gif

Be really careful how much water you feed in; it only takes a few ounces to hydrolock a cylinder. That would ruin your whole day. /ubbthreads/images/graemlins/jester.gif
 
Carbon gets hotter than steel, you are changeing the temp of the carbon vs the steel and thus breaking it loose and it then ejects from the tail pipe.
