I Dumped 20 Gallons Of Water Into A Running BMW Engine To Super Clean The Pistons. Didn’t End Well!

2. I, i, think you.. I mean what you're supposed to do is slowly pour in about a single small bottle of purified water. About a quart. With the engine running. That's all it takes. I would let the engine warm up for about 5 minutes also. Oh well I'm going to watch this it's might be fun.

3. I had noticed it was a rather cold day when you did this (winter). You want to do this on a hot or warm day (no snow). Engine needs to be warmer as well so it steams better. May of been to cool.

4. I use a spray bottle and spray it into the open intake with the engine very hot.
   I would do this in the winter‼️

5. Those Bmw's sell for crazy money in South Africa. $20k and up

6. Did you by Chance ride the Short Bus to School?

7. Just a simple water injection set up would be smarter and more effective and safer.

8. black chunks flew out of the tailpipe

9. You could have 6 small fish tank pipes joined together at one end ..then a water controlled valve ,and then put the line in a gallon container above the engine level . Put one pipe each in the intake runners
   So you can be assured .. you are not hydrolocking the engine at the same time , best equal distribution of distilled/ demineralised water in the engine ..

10. With that much water I would keep an eye on the oil amd see if any water is getting past the rings

11. "coke bottle tuneup"

12. I want to use Coca-Cola😂😂😂

13. Sadly there's no incentive to cure any disease money is made in management of the disease form the pharmaceutical company s.

14. For best effect, engine needs to be under load. Drive up a mountain with the water squirting.

15. Anyone who has pulled a head off because of a blown head gasket “coolant leaking into cylinder “ know the steam clean works for a fact….if done right

16. MMO works better and it won't hide in the crevises of the engine like water does, I own a classic car dealership, not like 50 fully restored cars, We do running and driving project cars, We will buy a classic car and get it running, driving and inspection ready project cars. The first thing we do is change the oil, we do a 25% mix with the cheapest "store brand" oil and oil filter we can find and MMO then drive it around 100-150 miles then change the oil again and take the oil pan off and clean the bottom end and throw the oil pan back on with a new gasket. it does an absolutely FABULOUS job.

17. Win a carvwith a blowed motor . Nah

18. My dad taught me this 20 yrs ago with a car they got me for my 19th birthday. It sat for a long time and didn't run great. We used an old windex bottle to spray into the throttle body. The old 91 Eagle Premier ran so much better after like half a windex bottle. Definitely worked wonders on that car and a few others over the years.

19. Mix brake cleaner, trans fluid, and WD-40, poor a little down each cylinder, let it sit over night, try to dry it up a little the next day in each cylinder, do an oil change, and then start it up and let it run for a while, it works wonders. It loosens up all the carbon and cleans it all out after it runs for an hour or two of driving. It’ll look real clean in there.

20. I use white vinegar

21. spoiler alert netflix blocks vpns

22. I believed it needs higher loads and higher rpm, like it would be good if you could do that on highway on 3rd gear and like 6k rpm

23. BMW will be so proud of you dude 🥹

24. Think it like thermal dyn. Carbon has b hot so cold water makes it explode off out🎉🎉chamber

25. You could have used I quart of transmission fluid in the intake while holding a raised idle speed And cleaned It good enough in 2 minutes.

26. I tried this one time wirh a car I used to have. I got carried away and put in too much water too fast and I broke a rod in half! 😢 Unlike gas, liquid cannot be compressed. So please be very careful if you're going to try this.

27. Hello, try half water and antifreeze! 🤓

28. Der arme E30 XD

29. What borescope are you using? Mine is not that crisp. And how much does it cost?

30. This method is used to clean the exhaust valve seats, but everyone that does it, seems to focus on the pistons

31. doing this there is a very high risk of hydro locking a piston. you need a flow rate somewhat comparable to injectors flow.

32. I have done this, put a vacuum T in the small line and reduce the hole size by plugging the end of the vacuum line and taking a small drill bit to make a small hole.
    You can zip tie a gallon under the hood and zip tie the hose to keep it in the water, refill the water from day to day and drive it around for a few days.

33. Hey Alex I really want you to revisit this! I want you to have the water pour in while driving on the highway. The engine needs to be under load with high revs and fuel flow. You see when a head gasket is leaking the cylinder is spotless, its because its going in when the engine is under load. Love you input dude keep it going.

34. Vapor lock you cant pour water in a motor you can spray the intake with a mist thats it
