Re: Decarbonising Engine with Water

So you're saying you fed your engine 16 ounces of bottled water via brake booster vacuum line and went to town on the throttle? Was the improvement immediate?

I wouldn't mind trying that on my Jeep on the next oil change. A bottle of water from the store is much cheaper than Seafoam. lol

No, the brake booster line is too big. You should spray or pour through the throttle plates / butterfly valve at a fast idle (2K to 3K).

Seafoam is still needed to add to the oil and the gas so it can clean the rings, lifters, valve stems and injectors as the water does not flow to those areas and would not be beneficial if added to your oil or gas.

I'm confused.

The brake booster line in my Jeep is maybe about half-inch in diameter. The throttle body is I believe about 4 inches in diameter. Unless what I'm calling "brake booster line" isn't really that. It's a rubber hose that I pull off from the brake master cylinder assembly and connects right into throttle body.

And yea.. It would be funny in a sinister way to pour water via crankshaft or gas tank, but not on my vehicle. lol

If you stick the brake booster hose into the water it will suck way too much water as you need to instead slowly pour the water into the hose (use a funnel in the hose if your aim is not dead on) while running at a fast idle. However if the hose connects to the engine where it does not equally distribute the water into the intake and then equally to all the cylinders that isn't a even cleaning as the closer intake ports will get more water than the further away ports. That's why any vacuum line is normally not recommended unless it opens centrally right behind the throttle body butterfly plates. It is best to pour slowly into the central throttle body or carb on older cars for the best distribution.

Gotcha

The air filter assembly is a bit of a PITA to disassemble but for this purpose it's worth a shot.

I'll post an update when I get to it. Thanks

Alright so earlier today I put apart the air filter assembly to acccess the throttle body (easier than anticipated, feel kinda stupid for feeling hesitant to do this after I did it). I did this after a nice 25-mile drive on the highway so the engine was nice and hot. I slowly poured all 16 ounces of bottled water down the throttle and started revving it once I heard the engine starting to sputter.

I guess either my expectation left me disappointed or I did this wrong. There were no "fireworks" or exhaust smoke. It sputtered for a bit while pouring in the water. Once I poured in all the water, I shut off the engine so I can put the air filter assembly back together. Then I took it for a spin, redlining it a few times for good measure. For right now it seems smooth and it idles a little less rough but this engine has the infamous Chrysler shake. It may idle rough one moment then it's silky smooth the next.

She's due up for the 3000-mile oil change in 1,200 miles, which at the rate of leisure driving that I seem to be doing lately this will take place next month. I think I'm going to pour an entire can of Seafoam right into the throttle body this time and see what happens.

Lots and lots of smoke

Yeah, no fireworks or magic genies.... sorry. However, you should see a dirty spot where the exhaust let out broken carbon as the steam in the combustion chamber shocks it into small enough particles to get blown out the tail pipe and on to the drive or ground.

Water burnt in engine = steam vapors and carbon on the ground or shop floor.

Seafoam cleaner burnt in engine = clouds of white pillowy smoke.

If this water trick and Seafoam do essentially the same thing via throttle, I'm almost preferring to do the water instead. The smoke that starts coming out with Seafoam makes me worried enough to get hit with a citation for polluting the environment. I normally wait until it's late in the day enough and find somewhere quiet and isolated to do it.
