Fuel injection cleaner

Plain water used with the proper technique does a more effective and faster job cleaning carbon out of combustion chambers. True.

I could have my combustion chambers sparkling clean and free of all carbon deposits in about five minutes with 12-16 ounces of plain tap water and the engine running :)
How do you do it?
 
How do you do it?

Here are @Jerry Bransford's directions . . .

"If your engine is carboned up, you can blow it out by the old "Italian tune-up" as described in another thread... drive the engine extra-aggressively for a day or two by revving it hard at WOT to near redline RPMs. Or use the age-old very slow trickle of 12-16 ounces (slow enough of a trickle to take several minutes to empty the container) of plain old tap water into the air intake while keeping the engine RPMs up a tad which quickly breaks up carbon deposits so they can be blown out the exhaust. No I'm not out of my mind lol. That was discovered in WWII after they started using water injection in aircraft engines for more engine power for heavily loaded bombers. The mechanics quickly observed that the engines were staying sparkling clean inside. That technique is still common on aircraft today, and it is still used by experienced mechanics to clean carbon deposits out of poorly running engines that were babied too much."
 
Thank you VirtualRussel. And can you give me a link to that post please, I'd like to add a minor edit to it.

Basically, take the air intake tube off the throttle body. Fill an easily controllable container with 12-16 ounces of plain tap water. Start the engine and VERY slowly start trickling the water into the throttle body while keeping the rpms up with the throttle lever on the throttle body. Empty the container and you're done. You should trickle the water slowly enough that it will take a couple minutes to empty the container.

Just be careful to maintain complete control of the container of water, it'd be very bad news for the engine if you were to accidentally dump a large quantity of water all at once into the engine while it was running.

Thank you fellas. This weekends task on top of new exhaust manifolds, down tube, O2 sensors, fuel injector cleaning, oil pan gasket, and rear main seal.
Anyone wanna help?:D:copas:

I use an old windex sprayer bottle set on mist for this.

Anything I've read about cleaning the combustion chamber out involved removing the vacuum line off of the brake booster, and slowly pouring the "stuff" in the hose.

Is going through the intake and the vacuum hose effectively doing the same thing, or am I way off base?

I can control the RPMs more effectively by leaving the brake booster hose connected and controlling the RPMs with the throttle lever as I trickle the water in through the top of the throttle body. It works for me.

Gotcha. I just wasn't 100% sure if it was doing the same thing.

It somehow seems scarier doing it through the TB though, lol.
 
Do you get big clouds of white smoke coming out the tail pipe like you do with Seafoam?
 
Just found this thread, for the technique described where you add water to the TB. You just say to up the RPMs. How high should you rev the RPMs to get the desired effect?
