Put regular oil back in. See how it acts.

I love how the BMI Russian guy translates in a walkie talkie voice when they are talking to each other in the cars 😂 Nice touch! ❤👍

Pull the spark plugs and check the cylinder walls.

These guys have the craziest ideas for cars bur it's cool to see them expermenting

A compression test before and after would have been interesting

There is a screen filter on the Vtec solenoid that can plug. Its something you can check in junkyards when looking for an engine. If the vtec solenoid is filled with swarf, its probably an engine to avoid.

I wanted to see what happened when they put fresh oil back in, took it for a drive then dropped that oil too (to see what the oil was like after the brake fluid had cleaned the engine) and if the VTEC still worked with the fresh oil. 🤔

A little bit of brake fluid in the oil used to be a dirty trick to reduce oil smoke, at least until the car sold. It would swell up seals and reduce how much oil got past, but not for long.

A true testament to how good Hondas engines really are.

I appreciate that they even translated through the radio for extra immersion instead of just voiceover. Nice touch

I think it would have been a great idea to change the oil filter, pour brand new oil into the engine and check for oil pressure and general performance

cut the oil filter to see what inside ;)

You should of checked compression before and after!

I worked at an oil testing lab. Every once in a while we would get samples where a Jiffy Lube type place would put motor oil in the brake fluid reservoir. It would destroy the seals in the brake system resulting in no brakes.

Run an engine on transmission fluid. An old idea is to add a quart of transmission fluid to old oil before you change it. Let it get hot and drain it in each oil change. It’s supposed to clean deposits so long term it stays cleaner.

Thanks for running this experiment. Your videos are interesting. Some people here in the States use kerosene to clean an engine's insides, allowing the engine to idle. They drain, change the filter and refill with regular oil. I don't recall anyone telling me if the engine ran better afterwards.

I'd like to see it filled baup with oil and see if it smokes less now being your valve seals are conditioned. Wonder video as always.

Good job man Hello from Florida USA Much respect to you

You guys just keep the fun going on, now change the filter and put fresh oil in and test drive it. this is down to earth good fun kudos guys.

Can you make a video when you drive a car with diesel in the oil? Like 40% diesel in the engine oil for 10 days and see how clean the engine got after that time.

9:17 Guy in passenger seat is like : "This is a bad idea. WTF am I doing here..?"

Hi from America and I always find your video entertaining. You just do anything what most of people wanted to do and couldn’t afford LOL.

I would like to see the same experiment but use lacquer thinner. Only don't drive it, it'll surely die, but try to clean the engine without killing it

Would be interesting to see how it does on a head gasket replacement oil change schedule from this point: replace with motor oil and then replace again after 500 miles and see how it reacts. Love to see the experimentation, thank you for sharing.

Try ATF next time, I use it on very dirty engines to flush out the sludge without hurting any critical components. Love your channel.

Dude the coms translation always gets me😂 such a master of the voice over craft

Do a series of tests with different additives (kerosene, lacquer thinner, paint stripper, brake fluid, transmission fluid, etc) added to at a 1:5 ratio to the oil like regular additives. Put each mixture into different engines with similar amounts of deposits. Then endurance run the engines for a week and see what mixture does the best. It interesting to see the extreme end of these tests that I love watching you for, but it would be really nice to see a few tests that I can apply to my daily driver.

I was hoping you'd put oil back in the engine and see how it did on its performance and oil burning after the brake fluid.

I never thought of it but now that you mention it, yes, I want to see what happens.

Put the brake fluid into a radiator instead of water. Brake fluid is heatproof too... Who knows what happens

Interesting.. less obvious damage than I was expecting, but I would have liked to see if there were metal shavings in the fluid, & if the oil filter was getting clogged w/ any kind of goop

Could have used transmission fluid as well and it's an oil so you would maintain oil pressure and have to be careful with the brake fluid being in contact with the crank, rod and cam bearings depending upon what they are made out of and if they are zinc coated.

Two fluids to always be carried. Trans fluid can be used anywhere oil is used in a pinch, but not for brake fluid. Water is best in a brake fluid system as it won't destroy seals.

I wanted to see how much it smokes after putting oil back in it. Maybe the rings got freed and it may seal better.

Scrub the inside of the oil pan thoroughly, and clean out the oil pickup screen and the screen inside the vtec solenoid. While the brake fluid has cleaned up the deposits, those deposits could very well get stuck to the oil pickup screen causing low oil pressure, and the vtec screen which will cause the sluggishness and no vtec.

get some crude oil, do a basic filtering of said crude oil to reduce it to just liquid particles, run the engine with crude oil in the sump.

Solid! Top KEK! peace be with you.

Keep it rockin guys 🎸

Damn it clean the hell out of it I wonder how it will run with oil now way to go y'all just knew it will get it fire

Fully synthetic oil has a simular effect. As an apprentice I destroyed a few neglected Honda engines. Thinking I was doing the right thing, the high detergent thin oil would get past the rings and turn it into an smokey oil burner. One of the old guys used brake fluid to decoke carburetor engines. Just hold the revs up at 2-3000 rpm and dribble the fluid down the carb for 5 mins, smoked like crazy untill you stopped with the fluid, even the plugs would come out cleaner, welcome to the motor trade🙂

Wow nice performance. Thanks. I enjoy this video so much

I bet the critical oil clearances are HUGE now that its smoked the rings valve guides cam and crank bearing, no doubt it was really hard on the metal to metal surfaces

I didn’t think I would make it to the end but this was super interesting.

Adding 1qt of brake fluid is an old used car lot trick to get valve stem seals and other seals to swell up slightly and seal better. You only run it long enough to get it circulated well, then just let it sit for a few days while it softens things up. Warm it up and change oil after that. It helped on my buddy's rsx commuter car with 200k+ and leaky valve stem seals

and now put some good oil in it and see if everything is fixed..?

This are really fun to watch

Can you make a video about putting a torque converter in manual trasmission with manual lockup. How it affect the smoothness during changing gears and power going uphill with out stalling the engine

Best car channel, ever... Sink into that Knowing...

My '07 Honda Fit has over 140k miles and is still going strong. Keep up on oil changes, throw some injecter cleaner in it every other month or so, it'll keep running for another 140k no worries. Honda makes good engines.

You guys are amazing. Automotive Destructive Testing Artists.

Fantastic experiment ❤💪👏👏👏👏👏

Of course the VTEC would work as long as there is enough fluid in the system to work the actuator. The reason it's burning so much smoke is because the viscosity of the brake fluid is too thin compared to the oil and it's getting past the rings, also why you can't get any oil pressure

I wounder if the caustic nature of brake fluid is not 'cleaning' things up inside, hence oil pressure light going on and off.... brake fluid has more than likely removed sludge from inside of the engine

Try transmission fluid wornder how the engine would run

Used transmission fluid next as it’s also detergent, so it might work really well to clean the motor internals

What about the bearings, rings, and valve guides?

I ran a small amount of brake fluid in my 92 Toyota forerunner with a 3 L V6 made it to 340,000 miles before the head gasket blue. It kept the engine clean and the lifter quiet. I ran that engine super hard all the time hitting the rev limit. I did have seals go bad on the cam. After 340,000 miles that was gonna happen anyways. This engine was also ran with vegetable oil. I definitely put thousands of miles on it with just vegetable oil in it. I did not treat it nicely and it held up.

Was waiting for standard oil test after cleaning, that should be interesting.

I had a thought today of what would happen if you replaced ac compressor oil with brake fluid. It would probably be fine for a long time and only fail on lubricity properties

I'm quite sure the main reason for the oil pressure light is a completely clogged oil filter. If the bearings were gone, you should have heard it already.

My Silverado brake master cylinder leaked a bunch of brake fluid into the booster and got sucked into engine. So I replaced Master cylinder and booster along with a oil change and filter. Still a bit of smoke out tailpipe. How long will it take for to smoke to clear up?

Could you replace it with iso64 hydraulic oil and see if it overheats or does damage. thanks for video

did it run ok on regular engine oil afterwards?

Try running some coolant in the oil to clean the engine. Idk if youve done it before. But like 1/4 coolant or 1/2. Cause the coolant desteoys carbon.

Love the shows is that a honda accord van. I never seen one of those in America

The crankshaft oil clearance is also clean and larger

2:50. Anybody notice the smile face on his light bulb 😂

I really enjoy this show or channel whatever you guys do some great stuff and come up with great ideas 💡

Ive been waiting for some one to try this for

Im curious how itll do when mixed eith oil. To be used as engine flush. The reaaon the brake fluid got thicker was it mixed with the oil still in the engine. There will always be oil still in the engine. And the deposits

A serious attempt at a repair involving this stuff is DEFINITELY gonna need a 50% oil portion or more; I would also submit my guess that a heavier oil would be a good idea.

Next run should be an attempt to completely clean the inside of the engine! Try several cleaning products like degreasers or oven cleaners, vinegar, detergent, brake cleaner there’s a plethora of possibilities although you might have to add some sort of clean oil like break in oil or Lucas additives or stabilizer. Obviously the engine will need some sort of lubricant or not I’d still love to see what will eventually clean that dirty girl lol

Comrades basically Brake Fluid is a Solvent so I'm not surprised your internal parts got De-sludged... if i were you guys i would put motor oil back in the engine & drive it to see if it still smokes

It's amazing the bearings didn't take a crap lol

Did you ever put regular oil back in it to see if it has good oil pressure? i cant find the video.

Would have liked to see what the bearings looked like after the experiment.

Can you test, if you use a pressure washer and motor cleaner for a pressure waster and wash the engine from under the valve cover and oil pan, will it help for the engine to work better?

I enjoy this channel, many thanks. How about putting diesel instead of motor oil 😝

I was looking for drones when you was out driving.

Awesome Video

I think the paint has clogged the oil filter, explaining why higher rpm is needed for adequate oil pressure

2:58 "VTEC gets a golden shower from 4 mechanics"

I agree. Putting oil back in this motor and seeing if the thing acts better seeing as all that cleaning got done, it seems like it should be rejuvenated 🤔 at least so far as the things that are still capable of doing their jobs are now cleaner, and hopefully able to do the job better. 🤔

Initially the brake fluid cleaned stuck piston rings, gaining compression but further driving with low-lubricity fluid wore out rotating and sliding surfaces. The oil pickup screen is probably also plugged with paint, carbon and oil residue.

Cool video although most likley that brake fluid is gonna eat away and swell the rubber seals in the enigne

You should try running automatic transmission fluid as engine oil

You guys should try a bunch of Brake clean Fluid in the engine and see how clean it gets.

Curious what will happen if you put a mixture of 50%/50% gasoline/diesel in the engine as lubricant. Will it wash clean or blow up?

Hm what about something insane, like pure water, or brake cleaner, but mixed with some additives. Can additives save the engine?

Alot of quik fix in bottles use mix of break fluid and other stuff

Would you be able to try 85w140 gear oil

When I was a young boy we would go to the school parking lot turn our bikes upside down, away from us and the building, we would get the back wheel moving using the peddles and drop a marble or a steal bearing between the tire and the rim to see how far we could get them to fly! One was 235 feet that was a bearing. So rig up a system to a Lada and drop steal barring's or marbles and see how far you can get them to go!

The only thing that dissolve oil sludge is drain cleaner. Caustic soda. I tried all the other products and they don't work. A couple of treatments with warm soda flushed with warm diesel and the pan gets clean. Don't let it cool down or you will get some red residue where the liquid surface was. I have never run the engine on soda instead of oil though, because the soda has particles. But I guess if you filter the particles of it can't be worse then brake fluid.

Thank you. Mick Australia 🇦🇺

use some BG engine flush if you can get it overt their, its the strongest flush you can buy, then chnage the filter and use some mineral oil for 20 minutes @1500rpm then put new oil in with a new filter, then it will run like brand new

Hi! Can you use diesel us oil engine? Thanks

I wonder if you had a really gummed up engine, could you drain oil, leave old filter and oil in filter alone. Full crankcase with Varsol. Just for a bit more lubrication is why I suggested leave old oil filter and oil in filter alone. Run it for awhile, drain, replace with new oil and filter. Will engine be better?

I am so impressed by the stuff you guys do. I need to learn Russian.

Did you put oil back in, then see how it ran?

Bottoms Up. Other than the paint, what ever happened to the head gasket, and Valve covers.
