Recently, I encountered a video on Youtube, where Eric decarbonized an engine through the carburetor with a cup of water. Given that my vehicle is a later model vehicle, I decided to research the method that would be most applicable to a fuel injected engine…and now, my head is just spinning. :blink:
There appears to be TOO MANY opinions regarding how to safely perform this procedure with out hydro-locking the engine, and none of them are definitive. In essence, I’m attempting to find the safest method for servicing my vehicle (i.e. 98 Civic with 219,000 miles).
With that said, here are the questions that I have in mind to prevent engine failure. The majority might seem redundant; but listed below are the suggestions that I have encountered online.
1.The total quantity of distilled water to be use safely throughout the procedure(e.g. 8, 12, 20oz)? A gallon was even suggest on Youtube, crazy as it seems.
2.The approximate rate of water being sucked through the brake booster (e.g. Is it approximately a teaspoon at a time)?
3.RPM range to maintain(i.e. 2000 or 3000 rpm).
4.Do I immediately drive the car after the procedure?
5.Finally, do I remove the CAT beforehand, and/or change the oil and the spark plugs afterwards (i.e. does the water mix with the oil and fowl the spark plugs)?
Thank you all.

To clean the injectors this is the best method. we are not interested
in the moving part just the cleaning part. The induction/decarb part can
be done a couple ways. CRC,sea foam and 3m will work for the intake cleaning.
You fog the intake with the spray.Good ol’ hydrocleaning is in my opinion good for good ol’ cars. Also, it works only where water goes, or a particular air stream. Also, I wouldn’t be pouring water in. I’d use spray can and do water mist. Works as well, if not better.
Back in my ol’ country, they used to drive with enema bag hooked up to throttle body, squirting some water vapor in to “improve mpg/power/add your whatever). DRIVING around like this. For years. So no major harm was done.
But the way it workd, water does not compress at all. 0 compression. When water droplets are sucked into air strem, they hit walls of any passage they go through, like tiny jack hammers. As the result, it’s pretty much pressure washing of your engine insides. Good. Q is – where does all this stuff go next? Combustion chambers, EGR, cat, exhaust.
As “gentle” as modern power trains are, I’d rather not have crud go through all that.
I’s rather do Seafoam via fuel tank (cleans everywhere petrol goes) and in oil (cleans everywhere oil goes).
As of the other cleaning agents, I tried many, and they either do nothing, or stalled my vehicle. Since 2001, that being 13 years, I am sticking with Seafoam. Btw, had a 99 Ranger drive around for 2500 miles with Seafom in engine. Just as experiment. No adverse reaction.Respectfully, I am not too interested in Seafoam given a lot the horror stories that I’ve read. Water just seems like a safer bet, provided that I can understand the procedure correctly.
I guess what I am really hoping for is a decent write up for decarbonization with water from the questions listed above. I am certain that this will eventually help more people down the road.
It’s always a mental safety that takes over. Understood.
I guess, it’s pointless to say that since 2001 I had Seafoamed every single car in the family, including quite expensive ones. That I keep Seafoaming all 6 of our family cars NOW at rate at least twice a year, both through oil and petrol. Including Lexus and Infinity. That I Seafoam engine 500 miles before every oil change. And as the result, all my cars run like Swiss watches.
But, as I said – it pretty much idle use of bandwidth.
Happy New Year.SeaFoam is an excellent product and if someone has had problems with it then the SeaFoam is not the cause of those problems.
Misting water into the intake while running the engine will decarbon it. A tiny bit of anti-freeze mixed in with the water makes it work even better.
Water and anti-freeze, just like SeaFoam, will hurt nothing the process is abused.
Oh that one particular video was most certainly my inspiration for wanting to do this; but what I’m attempting to do is learn how to perform this procedure safely to fuel injected engines, while eliminating all of the confusion from the internet.
Personally I’m not a big fan of such procedure. Did this for my late `97 civic few years ago. It burned oil at high rate, so I thought that oil rings may be stuck and this procedure might do something about that (oil rings were actually not stuck but gone as it turned out later). Used about a liter of distilled water (sprayed mist, not poured, pouring seems kinda dangerous to me, but that’s just me, holding rpms at about 3000). Mileage was about 200.000 miles. Procedure did nothing good or bad. I think regular oil changes and some high speed (and high rpm) highway driving is enough to maintain good engine health. I did this just before the oil change, I think it’s the best time to do that if you really want to.
