Water to fix plug problem
I was talking to a shop foreman at a local ford dealership and he said you could take water and slowly feed it in to your truck engine though the intake while it is running and it would clean all the carbon off of everything including the plugs. Any thoughts?

That seems very weird nor would it be something I would try. How do you "slowly" add water to your engine? Who's definition of slow do you go by? The only time I ever got water into a cars engine I thought I was going to blow the thing up...
Let us know how it works....lol.

IF you want to hydrolock the engine give it a try!
I won't be putting water in my engine.
I'm going to try running some sea foam through the truck(it decarbonizes things). Then soak the plugs with Kroil(which penetraites and eats the carbon off of the plugs while it lubrcates the extration).
Let the shop forman do that to his own truck while you watch, and then see if he needs a new engine or it works.

I've heard the old wives tale, seen it done in person a couple times, and seen it on youtube at least once:
http://www.youtube.com/watch?v=tt7IY0keOD0
I don't know that there is any hard evidence that it works - I've never seen anyone do a before and after shot.
My overall feeling is that the gap where the carbon gets stuck around the plug is so small, that it is doubtful that spending 10 minutes feeding water into the carb is going to effectively clear out the carbon.
When the fateful day does come for me at 100,000 mi, I plan to attack the carbon on every possible front. I'll be burning E85 so hopefully that will clear out some of the carbon from the combustion chamber side. May also see about running some extra injector / engine cleaner (ie Chevron Techron or similar) then follow the procedure with cracking the plug from the top and soaking in Kroil for a couple of weeks before hand. But the big key is time - lots of time! Very narrow gap so what ever you do is going to take a long time to work in there.

it sounds like the new methanol injection kits for the diesel engines.... but not totally the same, so i personally wouldnt try it.
although, on second thought, in the Coast Guard, we actually have a set up on our propulsion engines where we inject a mixture of kerosene/water/409 into our turbochargers, and that cleans them out quite a bit, if done correctly.. however if mixed incorrectly, it could blow the turbo up.
i would let the service tech do the job if you really want it done. this way if it is done too fast/too slow/too much, etc at least you didnt do it.

Corey-as I began to read your thread,i thought -another one who is going do dump the truck at 100,000 , lol , -I also have been thinking the same thing for the plug procedure. Just exactly like you have stated. My 99 5.4 superduty that i bought new off the ford lot,has seen alot off hard, very hard accerlation (i was in my early 20's when i bought it), raced it light after light, then i started to read here about plugs spitting out, so i changed them at 30,0000 and torqed to spec and then at 60,000 and never have had a plug spitt out of the engine. Everybody told me dont touch if aint broken, but I am glad i changed them and torqued them to spec. Now the engine leaking oil onto the exhaust, well I have learned to live with that.

Scott109, did you find the kerosene did anything good for the engine? Harm it in anyway?
Just to add, I've used Seafoam several times and think it is some pretty good stuff and I'm hoping some of that and the Kroil will do me well for the spark plug change.

MBBFord, back in the mid-eighties we had a Chevy Citation that would develop what sounded like a rapping sound in the engine every 5K miles or so. The first time it happened we weren't sure what it was or where it was coming from. Someone suggested that it was possibly carbon build up in the combustion chambers and to slowly run some kero right down the carb (or in through one of the vacuum lines - PCV valve line works good). The minute we did that, the noise disappeared and the engine ran quiet. We would have to repeat the process a couple of times per year - carbon build-up seemed to be a big problem for that car. So to answer your question - no harm was done and it actually helped!

h2o injection has been around for years my young friends it was used a lot back in the day to clean and for a performance gain. it still can be bought as a kit. if you would stop buying the cheapest gas you can find (its the cheapest for a reason) and spend a little extra you wont need any kind of cleaners. in tank cleaners do more harm than good call up roush or troyers and ask them if they recommend any kind of injector cleaner better gas has more cleaners in it. the amount in gas is set by the gov cheper gas only has the absolute minimum. do a search top tier gasoline.
