I have run water/isopropanol alcohol injection in a 4 stroke 1000cc turbocharged engine. Water-ipa injects into each intake track at 150 psi, the water alcohol mix is completely waporized when entering the combustion chamber. I've run this on many of my turbo charged Yamaha snowmobiles over the years. On teardown of the engines I've found them all completely free of carbon deposits inside the combustion chamber, on the valves, and on the top of the pistons. There is no harm seen from the injection of water. Reason for running water-ipa injection is the ability to run higher boost on pump gas insted of running race fuel. Poor man's race fuel is a nickname used for this injection. I've run 22 psi of boost making about 350 HP in the 1000 cc engines on pump gas. Side effect was a very clean engine in the intake and combustion chamber. Thank you for your videos, very informative, highly appreciated. Greetings from Norway 🙂

[@ProjectFarm]

Greetings! Thanks and you are welcome!

[@blendpinexus1416]

this actually seems like fun to do. more complicated than just putting race fuel into the tank but can be a lot cheaper when tuned right (and a computer can just remove the boost if the water/iso tank runs out)

[@jan-ovepedersen5764]

@@blendpinexus1416 True, I have a failsafe switch that reduces boost to the waste gate setting, not do destroy the engine when the Water/IPA tank runs emty. I have the waste gate setting to allow for a boost level that is safe to run on Premium or 93 octane for USA or 98 octane for Europe. It's the cheap way out, and when you are riding trails you don't have the ability to get race fuel anywhere. Most servicestations sell IPA and water is free at the tap.

I'm a big fan of the channel & just wanted to toss a quick comment out. This info comes via my father, who was a big name in auto racing back in the late 50's and before that an instructor for the Air Force just after WWII in internal combustion aircraft engines. His highest qualification was in the Pratt & Whitney R4360. The history of using water in ICE's is long and storied, and much of my dad's knowledge came front USAF research regarding the use of water/water methanol injection. The first time he guided his very skeptical son through using water in an engine, it was accompanied by this: "Son, this car has been driven for years around town on short trips. This has caused it to get so loaded up with carbon that it's not working the way it should. When you dump a large quantity of water in a hot engine, the water soaks into the carbon, turns to steam, and blows the carbon apart. Once the water cools the engine down, it won't do any good. Once the engine is good and hot, manipulate the throttle to keep the engine running and DUMP A QUART OF WATER DOWN BOTH BARRELS OF THE CARBURETOR AS FAST AS YOU CAN WITHOUT KILLING THE ENGINE (it was an AMC 343 V8 and only took maybe 8-10 seconds)." I understand that much of the advice about using water to clean engines has been to feed over a longer period of time. However, executed as my father instructed it is effective and does not contaminate the oil. I run a performance sportbike equipped with water injection and have never had oil contamination. The rate of feed is critical. Water injection is far slower than in your test, and cleaning is faster but of VERY short duration. Thank you so much for your good, unbiased and scientific testing.

[@ProjectFarm]

[@davelowets]

I wouldn't waste time with water/meth injection on an engine as a performance enhancer UNLESS the engine was boosted.... There's really no benefit to it on an N/A engine.

[@SteveP-vm1uc]

Many years ago an old timer mechanic showed me how he "steam cleans" the combustion chambers in car engines and I have done it many times myself, though not in many years now! Start the engine with the air cleaner off. Bring it up to tamp and raise the idle while pour water slowly out of a jar/cup and while it tries to die, raise the RPM higher to keep it running. I have seen a difference on spark plugs before and after doing this, so I have to imagine it helps clean everything else in the chamber!!

[@glennyerger760]

I just watched two episodes of attempting to remove carbon from a cylinder head. Water, then Sea Foam vs Marvels Mystery Oil. Back in the early 80's when I started tinkering with engines I used the water followed by transmission oil to recondition piston rings. Over the years I have used Berryman, and STP, products. However, watching your videos I believe that the MMO product does the best and can treat more common problems from fuel cell issues, head & upper cylinder, to rotating Assemblies.

Last question... Yes I would and do use water. Always have. As in the other suggestion I actually switched to steam with wand applicator. The steam is what cleans and its already in steam form and much easier to deliver especially in a fuel injected engine. I do suggest using the steam wand ... I believe you will be impressed with the outcome... Maybe use a vacuum pump on a small engine to help with the crankcase. Although you should see less with steam.

I would never put water in my engine 'cos it seems so counter-intuitive.

I am pretty biased about Seafoam which I think is great but I haven't sprayed inside the carbs yet. Question. my old supercharged Jag 2004? Mi bambino? isn't it true that if I put one of those 'Restore' liquids in the engine though, for the next ten oil changes or for the rest of its life, I will have to put at least the same amount every time I change the oil?

You don't need that much water. About a cup or so should suffice, administered with a spray bottle into the air intake. Should be a job measured in minutes, not hours.

[@ProjectFarm]

Thank you for this recommendation.

[@drhjr7516]

Yes! What I do to clean fouled spark plugs and clean the carbon off the head and valves is just take a glass of water and slow pour(1/2oz at a time) it into a car carburetor, or take off a small vacuum hose and let it pull the water straight into the intake manifold. The water goes in, and under compression then flashes into steam, shattering the carbon. Who told him 2 hours? and how much water?

[@03056932]

your point would make sense if the cylinder head in the video was completely de-carbonised but it wasn't. minutes would have made barely any impact.

[@seanthenry]

The engine temp dropping does not help, if the water was cycled it would have worked better I feel.

[@DommoPA]

I agree!

[@eddiekilby]

The way It works is with the engine at operating temp rev it to about 2500 Rpms add a burst of water. The water cools the carbon deposits on contact breaking them free from the engine surfaces. You don't run the engine on water constantly. It needs to be added In short bursts To allow the surfaces you cooled to heat up agan.

[@danielbargas3377]

Eddie 27886 this guy gets it

[@johngotna3553]

In doing this process, the steam is what cleans the combustion chamber. Every time I’ve seen this done, the engine was fully warmed up and small amounts of water were poured in periodically (not constantly fed for extended periods of time). The cylinders have to be kept hot for this to work. The engine got way too cold in this video and the water was not fully vaporizing when entering the chambers. This is why some started to make its way into the oil. I would encourage you to try this again, but instead of a constant trickle try adding small amounts by hand 3-4 times-giving the engine time to warm back up in between.

[@thejuul8718]

John Gotna I just posted the same thing you said before seeing your comment. I agree with you.

Also use a mist spray of hot water or steam. Be sure the engine is HOT. Best if the water is steam. Thats how Ive done it for along time. Im 67 yrs old

YES. This is how it is SUPPOSED to be done. Large gulps at a time, and a rest period in between to build up chamber heat again.

[@The_Guru_786-n2r]

You are spot on . He cooled the engine way below normal operating temperature and didnt allow the water to evaporate and steam the engine. Instead the low temperature converts the little bit of steam to condensate, which explains the water blow by through the piston rings, into the crankcase

Great video :) I have used water to clean my engine head/valves, but the way I did it was to warm up the engine, pull off the air filter, rev the engine to 3-4K rpm and then spray carbonated water from a bottle into the intake directly for a few seconds. The engine doesn't sound happy when you do that, but afterwords it runs fine again. Still, that is a quick-fix only, until you have the time to take the engine apart and clean/inspect thoroughly.

[@bcseo7446]

Great topic! As a wrench and smog tech for 18 yrs before switching careers. A poor mans trick on NOX failures on smog was the water in the intake trick. Definitely works as I always saw a substantial drop in NOX confirming carbon cleaning and hot spots in there gone. I will say, I believe thered be better results with applying water and varying throttle. My program was to rev up, pour in and continue applying throttle as rpms dropped. Usually just 4 or 5 quick blasts was all it took. Seafoam? I always chose to use GM top end cleaner for the real job of top end cleaning without pulling heads. That stuff is amazing.

[@davidschmidt6013]

HAven't watched anything here yet, but I will say, before starting (just to keep it interesting) : we dinosaur hot-rodders used to cobble together quite a few different variations on water-injection systems back in the 70s-80s to 'extend' the combustion cycle-time just a tad, while not messing with the actual ignition timing. Some people swore by them, others swore that they were just another fad that was useless unless one had an entire garage full of hi-tech diagnostic stuff to measure the variables with. Personally, I think the results varied greatly because of the amount of difference in everyone's engines at the time. The diff's between Chevys-Pontiacs-Fords-Mopars etc, displacements, manifolds, carbs, (this was before FI), exhaust flow-rates/pressures, etc and the variations in cam and timing specs etc. made almost any comparison, other than that of one engine to another of the exact same make/year/displacement etc., almost useless. Most of us tried it, decided whether it worked for us or not and either kept it or disconnected it. I built one on a '66 289 2bbl 4-spd Comet, drilled/tapped into the manifold on both sides of the base beneath the carb, stuck a .070 jet into the end of a piece of copper tubing on each side, that seemed to help mileage when I was cruising; but when I was out 'racing' and strutting on the weekends, I just shut it off, since it seemed to cut down on throttle response. But that's just me, and THAT engine, with THOSE specs, etc. Damn, I miss that car... as we used to say, that car would really 'shit n' git'... Kids today have NO idea what they're missing (same as with the music)... Years ago, I remember taking my friend's nephew on a ride in my all time favorite car, a '70 Challenger 440+6. My friend was working on his car and needed a few parts (nuts n' bolts stuff) and instead of him taking his car down off the jackstands etc I said I'd go to the store for him. I got in, and his nephew asked to come with me. As I was buckling up, I told him to do the same and he actually laughed at me. I laughed back, then punched the gas and took him two blocks in about 1.8 seconds, then hit the brakes. He closed his mouth, nervously buckled his seat belt and kept his mouth shut the whole time till we got back. LIFE LESSON LEARNED: and the lesson is: "Kid, back when Detroit had balls they used to sell some bad-ass machinery. If you get in a '70s muscle car, and the driver tells you to buckle up....there's a REASON!" American Muscle!! Never equalled!!

First of I have to say I love the way you try and be as fair as possible. I really like your stuff! I was first told about the water treatment 55 plus years ago and have used it many times over the years. I get the engine up to operating temperature and have about a quart of water ready. With the engine running at a fast idle I run the water through as fast as I can without stalling the engine. Once the water is gone I shut the engine off. After the engine has cooled right down I start it up and rev the engine up and down about ten times or more until the carbon quits coming out. It works great On cars trucks and tractors but I must admit I have never done a lawn mower lol. The idea behind it is that the water gets into the carbon and breaks the carbon up. The cooling breaks it free. Starting it up after just blows it all out. Anyway you did it one way but the principle did not add up to me so sadly it didn't work out. Maybe try it out the way I do it. Thanks for all the stuff you do!

[@ProjectFarm]

Thanks so much! Thanks for the feedback.

[@dominicdo]

Great video. I also did what you did on a 2015 Kia Rio and let the intake slowly suck water in, unfortunately i bent the connecting rod. I later discovered that this was due to the intake manifold design of the vehicle, some of the water was getting into the engine and the rest started pooling on the bottom of the intake. I did a snap throttle and all that pooled up water go into the engine all at once hydrolocking it. I have done this water trick for the past 25 years and never had a issue but like you said you always run the risk of damaging the engine.

[@ProjectFarm]

It's as old as the hills to use automatic trans fluid to keep carbon at bay, as an old gasoline engine trucker we always put AT fluid in the gas tank, it lubed everything . This test you did works because of the cool liquid is what breaks the carbon off the hot parts. However not to many took the engine apart.

trans fluid the carb for carbon breaking; and a pint (to 4-5 quarts motor oil) in the crankcase to dissolve slug and carbon build-up, plus it keeps all internal rubber seals supple...

[@marknye51.thefixitguy]

Interesting facts to consider. I have been doing small engine repair for almost 40 years and it seems that Water or Moisture that gets into the Gasoline on these small engines( lawn mowers, trimmers, pressure washer etc..) will turn the fuel rancid and usuable plugging up the carburetor, eating up fuel lines and build up in the combustion chamber. I've used seafoam or berrymans fuel combustion treatment for all these engines and even in my vehicles and it helps keeping the moisture out of the fuel system and makes these engines run better. These products also will keep the fuel from going bad. Thats what ive found using these products. Thank for all your videos...

[@joelbrown7485]

Michael Wilson how dose a fuel injection motor have no carbon buildup when your still running a carbon base fuel if there is no additives in the fuel it doesn’t matter how you put the fuel in the motor it is going to have carbon buildup

[@scottwinkler2497]

Water added to the intake, fast cools and FRACTURES the carbon deposits in the combustion chamber. That is why you need to have the engine up to a very high temp before you add the water. After the initial hit of water, it has cooled down enough it will not do any more good as the carbon is not red hot anymore and it just runs the water through the engine and as you found out, dilutes the oil. Sea foam is a chemical compatible with fuel and oil so it reacts favorably to the gas and oil when exposed over an extended time as you did in this test. Hard to compare the two in this manner when the water only cools and fractures the red hot carbon and blows it out the exhaust and SeaFoam chemically cleans the carbon after it cools it. I really like all the videos you are producing! Very thorough, fair, and relevant to most of us gear heads.

Thanks and you are welcome!

[@CatDaddyTuning]

Usually I run a gallon through a car engine in about 15-20 minutes. It requires a slight throttle opening to keep it alive but the engine stays hot enough to keep it rolling steam. I thought the video was great though!

[@RockandrollNegro]

Project Farm, for the question you asked at the end, "Would you use water to clean deposits in the engine", I have, but never had very good results with it compared to a volatile liquid like Seafoam or Marvel Mystery Oil. It's true, water can have really good results, but the thin line between positive results and failure is too narrow for me. From what I've witnessed, it's not really water that's doing a cleaning, it's steam, and to get the right balance between pouring water/creating steam, you run the risk of hydrolock and water mixing with the oil. Now, hydrolock is a risk no matter if you're using a solvent or water, but where something like MMO, Seafoam, B12, or Gumout can safely creep into the crankcase and intermingle with the oil, water can't. And a solvent treatment, unlike water, is not really dependent on temperature. You don't have to worry about whether you're misting or pouring, or whether the temperature inside is enough to create steam. In fact, I've had the best results from pouring MMO or Seafoam straight into the spark plug wells, sitting overnight, bumping the ignition to spray out the excess, putting the spark plugs back in and running it rough for a bit before changing the oil. You really can't do that with water. (You could, but your motor wouldn't be very friendly to you afterward.)

[@danthomas9077]

Yes it's steam you need to clean, engine needs to be hot, these briggs and the carb/manifold system on them doesn't get hot enough for vaporizing the water. With a little alcohol added to steam I'll bet you might get an engine to run on a water/alcohol mixture only, There's about 2 cups of water in ever gallon of gas, you see it coming out a cold tailpipe on cars, there's also hydrogen in water and a lot of cylinder pressure developed by expansion of said water to steam, some of the hydrogen liberated is also burned. I did some studies of high mileage carbs and all the principals of best and most efficient combustion rely on high/er operating temps and more complete vaporization of fuel. It's not a big deal a little carbon in the cylinder chamber, where is it proven that a clean cylinder is any better better, looks nice but is it better? Carbon is a thermal barrier, keeps combustion heat in the cylinder, if ya don't have overheating problems that's a good thing, it's why you gunked up the piston cause it was running too cool, and your compression test being higher after the water test might be simply from the carbon/junk deposit build up on piston raising compression slightly.

Used water many times, but never over the span of hours. My dad (certified mechanic for Chrysler back in the day) and I started doing this in his old company car, which he never ran hard, mostly constant highway miles running maybe 10 over the speed limit. There would always be lots of carbon buildup over a couple of years. We would use a couple of Coke bottles worth of water and just pour sips in as the motor could take it while throttling the carb. as needed. The whole process took only 10 minutes of non-continuous feeding of water. The difference in power afterwards was quite noticeable to the "seat of the pants". I remember seeing all the "smoke" coming out of the tail pipe (as a kid), :-) We never changed the oil after and never had a problem. This may be due to the relatively small amount of water, for a short time, mostly blown out the exhaust (steam). Super impressed with your testing by the way, interesting and very appreciated!

[@ProjectFarm]

Thank you for the feedback

[@REPENTINCHRIST]

YES!!! I am ASE certified through college and hands on, and this may sound crazy but standard practice taught by the engineers is that AFTER the seafoam the same amount of water needs to be introduced the exact same way (use 1ltr bottle with a little hole in the lid to spray), and the water actually is more abrasive and breaking off any remaining deposits that the seafoam has eroded. The water is actually the main catalyst to removing deposits as the seafoam is to breaking the bond of deposits. Through the engine performance course a student was introducing the Seafoam through the brake booster line by SLOWLY pooring it in and accidentally sucked too much in at once and hydrolocked the motor, BENDING A ROD! so the spray method before throttle plate done in another vid is MUUUCH safer!!!

I haven’t read any comments (yet) and about half way through video. I keep thinking though … When using water … Seems to me that a step was missed. Idea is steam. Steam is what’s gonna clean. You would have to keep an eye on engine temperature, making sure that when engine temp dropped below let’s say 200F or so, water feed is stopped. This would also ensure the engine doesn’t hydro lock by accident. Great vid!

[@daveclair9954]

In the leaded fuel days, we used to see carbon buildup to the point of causing knocking. Similar sound of rod knock. We would slowly pour a glass of water down carb., and shut off engine to let steam loosen, then restart, and repeat until knock went away. I have not seen this since lead has been removed from gasoline. The amount of carbon shown is harmless.

[@mbakken11]

FWIW, a lot of these small engines are fit with custom cams or decompression features to allow for easier starting. This usually translates to lower than average compression readings and most suppliers advise against putting too much weight in them. Instead they say to do a leak down test. If this thing really only had 60-80psi of compression it wouldn't run this well and it would likely be puking blue smoke the whole time.

[@davehennon4146]

I have added water to my engine many times and would do it again if I thought it would need it. Normally though it's a quick process. Wild revving the throttle give the engine a quick slurp of water two or three times. The science is that that cold water it's that hot combustion chamber causes an explosion and blast the carbon loose. But the engine has to be hot whereas the way you did it obviously the engine was cool down as you trickled the water in. I have torn down motors with lots of miles on them and found the combustion chamber and valves to be surprisingly free of carbon. Quick simple and you don't get water in the oil. Love your work.

[@gweedomurray9923]

Like other viewers I enjoy your painstaking detailed investigations of various products and appreciate the time and effort to disassemble and reassemble machinery in order to illustrate the process/progress of a treatment. I might suggest that when injecting water that you do it as a fine atomized mist or from a steam tool. The amount of water you were inserting was way more than the engine could process, made obvious by all the mixing of water into the oil. I had seen for myself on an old Ford I had and was told by an uncle who ran an Esso/Exxon station for a number of years, how a customer whose car had a coolant leak into a cylinder had shown the valves, the head and piston top to be clean right down to bare metal. I believe the water introduction has to be slight in order to not adversely affect combustion chamber temperature otherwise you do not get the benefit of true steam cleaning. I use a handheld steam cleaner with the steam directed in after the mass flow sensor on my '99 Tahoe, through the hole that the PCV air is drawn out of. There is a drop in rpm which is brought back up to the high idle speed that I do this at. I have a homemade tool for holding the accelerator back while I hold the hose up to the port. I can only guess how much effect this treatment has as I am not wont to pull a head off for inspection. It has not caused any lack of performance and at 344 K plus it is running very nicely. I have run steam into my mowers and did not get the oil like what you had. My steamer is a Perfection but there are other brands on this page. The capacity on mine is 8 ounces and I do the car treatment in blocks of three. www.google.com/search?client=firefox-b-1-d&q=perfection+steam+cleaner

[@gweedomurray9923]

@DESTROY white supremacy BY ANY MEANS NECESSARY ~ Unless you pull parts for visual inspection you can only go on any possible improvement in performance. Spray your air intake line post mass flow sensor with carb cleaner or chem of your choice to make sure there are no leaks which will affect how the engine runs but wont show up as a check engine light. I found where the tube mounts to the throttle body, to be letting air in which will definitely affect shift points. The Silicone "ring" gasket at the end of the tube was damaged. I inserted one or two of those O ring gaskets that they sell for the household water filters, about a 3 inch O.D., and with some non hardening gasket sealer, tightened it up nicely. I found the leakage with carb. spray. My 3 stage, possibly soon to become a 4 stage oil vapor catch system DOES keep the liquid component from going back into combustion which makes for pretty much all the carbon that accumulates in the combustion area. If I had a GDI car and access to PCV vapor flow ie, a hose, tapping into the line would be the best way of filtering out muck from going back into the engine. I had read that some, at least, current engines don't have the PCV vapor flow as an external circuit. Two GDI systems, one being Toyota, have a hybrid injection where it alternates between GDI and standard injection which sprays gasoline onto the intake valves, in effect "washing" them to reduce or eliminate carbon build up. Scotty Kilmer did a video on that. I usually get an oil water emulsion from the first stage vapor can, and that mainly happens during periods of high humidity. 2nd stage has also shown emulsion at times while the third stage, a glass bottle, produces liquid oil. I am thinking a 4th because after about a 4 K trip this summer I saw the faintest amount of liquid oil on the PCV intake. My vapor system is entirely homemade so the appearance is a bit rough. I may take pictures one day and link to my Flickr page. The collected effluent goes to recycling along with used oil from oil changes I do. I would like to know your steam treatment results and sincerely hope "Farm Boy" can do the test. His thorough method should be enlightening. Good Luck ! Gordon

I’m sure you’ve heard it quite a few times already but I would recommend using a spray bottle and misting the water in or injector nozzle with a container connected to regulated air to pressurize the water to be able to mist it. Also what temperature was the water? I use hot water to clean carbon due to the fact it will not cool the combustion chamber as much. The reason a blown or leaking head gasket cleans so well is that it is heated coolant and steams it. I guarantee with a spray bottle with hot tap water will provide drastically improved results.

Revved the engine opened secondaries and pint at a time, blasted all nasties out the side pipes of my El camino. No water intrusion. Just a large tumbler of ice water... 1979.( He was a master mechanic in the army) rest in peace.

LOL! Yes.

[@jetsmini]

Water injection during boost on my Mini worked very well. No carbon on my pistons at all and use less oil between oil changes. Compression went up too. It works.

[@ProjectFarm]

Impressive results! Thanks for commenting.

Thanks for the feedback.

[@foadrightnow5725]

The water should have been misted in instead of being allowed to trickle in. I think it would have made a difference overall.

[@ProjectFarm]

Thank you

[@kennethschultz6465]

No not at All ... The hot enigen waporizes the droplets

[@jabbajawz]

@@kennethschultz6465 That's the point. The steam actually does the cleaning. At the point where the engine cooled down to less than 212 degrees, I knew it would be a problem.

[@Scottross93]

Agreed, you should aim to keep the engine above 180*f at minimum. Water injection can help clean as well as help provide more oxygen as well as keeping cylinder Temps down for better combustion. Generally its used in forced induction engines to help compensate for the heat produced while compressing the air. But you dont want to run the injection the whole time as you'll get what we have here. Short bursts of maybe 30s when the engine gets up to temp (which looked to be around 220*f on the head) spray it until it cools down to 180*f and let it get back up to temp

[@LygerTheCLaw]

water injection as a form of decarbonization tool works best when the water isn't atomized and is more raw in form, if you want to use it as a form of knock suppression then it works best as in atomized form.

[@s00p3rman]

I've heard that some old motorcycles came with water injection, to lower cylinder head temperatures and reduce deposits. I think it works better if the water is in the form of vapor. if you had a fog machine, or a fine mister, that would be ideal. it probably works better as a constant ,preventative feature, rather than a one time treatment.

[@nblax41]

Correct, OEM solutions are always water injection, not an IV drip lolol. Water injection is an old racing trick that has made its way to the public roads a few times in various bikes and cars

[@ProjectFarm]

Joshua, I agree...a water mister would have been a better approach. Thanks for watching the video and commenting!

[@twentyrothmans7308]

Water injection was also used in some turbojet engines to improve performance. Misfuelling with jet fuel instead of water in the tanks led to this : en.wikipedia.org/wiki/Paninternational_Flight_112

[@s4ms0n1t3]

That's basically why meth injection is, sprayed in a fine mist to keep temps down and increase power

[@Cyberhound-vu1re]

Very impressive! I want to thank you a lot Project Farm. You are absolutely amazing! Also, maybe trying this with engine coolant will serve a different effect? That is known to clean sparkplugs, and maybe carbon too? I've seen engines run on their own coolant and it doesn't impact the oil that much. P.S. Subscribed. :) I would say it's a competition but in Florida, it's so humid that engines basically run on water and fuel!

[@ProjectFarm]

Thank you! Thanks for watching and subscribing! Thanks for the video idea.

[@pangert1]

Wow! Thank you for reading the comments sir! I really love your channel and the way you go about things. Very impressive 😅I appreciate that you did the water test I recommend 😅

[@ProjectFarm]

Thanks and you are welcome! Thanks for suggesting this video idea.

[@Questchaun]

Came here to see how long it would take for the oil to get contaminated Wasnt disappointed.

[@ProjectFarm]

Thank you very much for the positive comment!

[@johns5591]

Ever hear of the Crower 6 cycle engine? Water injection and the flash to steam creates a second power stroke. ( yes it's real) however in testing attempts to move this design toward usage water contaminating the oil and the overall problems with cylinder/ring wear and sealing have thus far not able to be overcame. The designer is Bruce Crower of Crower Cams (hi performance cams)

[@rosseryn8216]

@@johns5591 Had not heard of that, will look it up. I ran water injection years ago for an overworked motor that got hot when pulling trailers (67 Dodge), it was a home made system water (jug, hose, small needle valve to throttle flow) run into vacuum line at the bottom of the carburetor. I read all the stuff about how it didn't work and would ruin a motor but my dad (engine builder, machinist, metallurgist ) and an old mechanic I knew talked me into trying it. Since I had already done everything else (radiator ,flush, water pump etc.) I figured why not. The results were that the motor temperature dropped about 20 deg., I seemed to have more torque and got a little better mileage pulling trailers (about +1.5 mpg). Every thing I read said this could not be, however it worked. The diesel effect was all we could attribute it to. That motor was the original motor and had been a daily driver from day one, supposedly had never been rebuilt, I was the second owner in the mid 80s, no idea how many times the odometer rolled over. The first guy used it to feed cows and general ranch work. I used it to drive to work and general farm and ranch work. The third owner rebuilt the motor in the 90s. Last I heard that pickup was still on the road in mid 2000s.

[@miketheis53]

@@rosseryn8216 We used a water vapor system in the seventies on my dads Chevy truck. Bought it from J.C. Whitney. Seemed to help. Compression and gas quality were changing in them years, had to try something. Like I said , it helped but in Minnesota we can't run it year around. Probably should have filled it up with wiper fluid....

[@93sundance]

I think since the head was off, just clean it by hand.

[@ProjectFarm]

93sundance, Makes sense. I chose to leave it, since I'm using the same engine for an upcoming test with ATF to see if in can do what water couldn't. Thanks for watching the video and commenting!

[@keantoken6433]

I'm not sure the results of this test are valid as a result for water. If you look closely you can see that new deposits were formed on the piston top although everywhere else looks pretty clean. I suspect these deposits are due to oil or unburnt gas depositing on the piston, and not being water-soluble. Since the oil level was raised it may have gotten behind the piston, in which case it would have been coming back through the rings just like the water was being blown the other way.

[@tylerbonser7686]

oh so youre a joke maker

[@Justinwhat1]

The point isn’t to clean his engines-IT’S TO TEST AND SEE WHAT WORKS (without having to disassemble).

[@hoghogwild]

Which is exactly what the engine manufacturers recommend, a manual decarbonization of the combustion chamber after so many hours. IIRC 500 hours on the old Kohler single cylinder K series engines. Cool test though, supplied water for too long though.

[@usernameandpasswrd]

You might wanna give 2+2 a try. I’ve used it direct in the tank (about 1/2 can to up to 2 gallons of gas, and direct spray it into the intake and it works well cleaning up carbon. I’d be interested to see how it shakes out compared to seafoam.

[@ProjectFarm]

Thanks for the suggestion.

[@308dad8]

I would too. Been using SeaFoam for 13 years or better now and it works wonders.

[@jasonlee5317]

Clearly seafoam wins this contest. It doesn’t risk engine damage.

[@georgehofgren6123]

Normally love this testing, but this time i think i might have to take exception.... The low temp and water flowing everywhere indicates it wasn't really steaming and immediately evacuating the cylinder. That would be more like "washing" the carbon off with just water. Which in this case seemed to just smear it around over time (but cleaned the valve edges nicely). What was with the whole 'drip-bag' thing? I'm assuming you were automating it to go do other things. This really should have been done with the motor running fast, (already warmed) and then just Misting in water a pump or two at a time. Maybe enough to slow it some but then let it fully recover and warm back up. The explosive action of the steam, especially directly on the hot surface of the metal is what removes the carbon. It's a Mechanical action, the water isn't acting like a solvent at all. That's why folks are recommending it over Seafoam. Just to satisfy yourself (PF) i honestly feel you should very breifly redo this by just Misting water into the intake with the mower running hot and fast for a brief while and then just immediately pull the head and see if the difference isn't noticeable. If so, Then if you want you can ammend or add comment to this video. Yeah, you prolly won't see this comment after so long, but if there's anyone who would, it would be you. Thanks for the work ☮️ gh~

[@ken2tou]

Great points! I was thinking the same thing. I’ve used the water treatment years ago on older vehicles with success. I’ve mostly used Seafoam in my motorcycles as a preventative maintenance measure, keeping buildup from occurring. If it isn’t there in the first place, there is no need to remove it. I’d add it, or MMO about every fourth tank. Both work well for me.

[@john2ndname]

@@ken2tou Well said!..i totally agree with you!...cheers!

[@tomvisel2267]

Three things: If the cylinder head is getting that cool, there is a chance that the sweater isn’t getting hot enough to have the effect that it might if everything were hotter. SeaFoam might have contaminated the engine oil the way the water did, but didn’t get noticed due to miscibility and color similarity. Auto engines have PCV (stress on “positive”) systems that let in fresh air on one end of the engine and evacuate that air plus blowby into the intake downstream of the throttle blade. IOW a car engine isn’t at as much risk for oil contamination as a small equipment engine because any vapors (again, if the engine is hot enough) get carried out of the crankcase and out of the oil. Love the show, good rhythm and explanations of each potentially non-obvious point.

[@ProjectFarm]
