Act like an adult. Have some respect.

That's "holier than thou".

What a cluster f#$% over something so easy to test. I suppose endlessly arguing about it on the internet consumes less gas than actually testing it in real life. I tested it and it definitely reduced injector duty cycle. I'm pulling together the parts for a more permanent rig that I can actually drive around with.

How about throwing a soaked sponge into the bottom of the airbox and give it a quick try, my Ranger 2.3 definitely runs like a kitten on a foggy night , Be worth it just for the improved engine smoothness. will try today going to work , about 130 miles roundtrip

About 1/3rd of the head was only 1 millimeter from the top of the piston and carbon buildup would cause a knock that made most people think the engine was coming apart.

We would use a pair of vise grips to lock the throttle at about 2500 RPM (air cleaner removed) then set the paint gun to a certain amount of atomized water and let her run for 15-20 minutes. It always worked, you could see the clean tops of the pistons through the plug holes and the knock was gone, and you had one tickled to death customer who had his engine knock fixed for less than 1 hours labor and no parts.

I've done this before, only just open the TB by hand and mist the water in with a spray bottle (as I have no spray gun). A guy on a Saturn forum hooked a vacuum hose to a water tank with a small restrictor in it so that the engine would suck in a small amount of water under vacuum. His cylinders/intake manifold are CLEAN.

I've thought about doing something like this, knowing full well it would have no positive effect on fuel economy. The Saturn engine is very susceptible to carbon buildup (especially on the rings), so it may be worth the effort. The potential for added moisture in the oil would concern me though.

I guess you don't want to have your logs examined, after all.

Good luck with with your setup. It'd be interesting to hear your results.

Just one quick question, though - did you run your test while the engine was under gar and under a real load, or did you run your test while the car was parked?

Yep. Water is probably the best liquid I know of for use in cleaning combustion chamber surfaces. Doesn't take much, either.

It's not such a big concern. You'd probably do more damage if you did a bunch of drive cycles where your engine wasn't fully warmed up before you shut it down. Whatever water gets caught in the oil will evaporate out.

I run water injection on the diesel and can burn a few gallons a day. I closely watch for signs of excess water in the oil, so far none.

When I was a teenager in the mid 1960s, Pop had a 1950 Dodge with an oil bath air cleaner. He tried replacing the oil with water, but saw no improvement in mileage. I'll bet it got rid of the carbon.
