Thanks bro you gave me a great idea, I have an engine that I pulled out of my car and removed the intake manifold, I'm in a desert region in Southern Arizona so there's light debris and maybe light surface rust from moisture, I stored it outside for 2 years and ready to put it back in but wasn't sure about the best way to clean the valves and valve ports, thank you for this helpful information

Great job & straight to the point . Subscribed !

Excellent experimentation and presentation, thanks.

I need to do this on my mazdaspeed 3. But I don't have any of the tools but this looks like it works well. I'll give it a shot before I go and get a media blaster. And deff +1 on making sure the valves you're cleaning are TDC.

Do that often enough the engine should last forever!

Always useful videos ❤️

يدك خفيفه واتقان ممتاز جدا عملك ناجح ومضمون وفعال انت مهندس شاطر

Great video, I have a Mazda 6 with exactly that fault it’s in garage now being fixed .

I do that to my Peugeot 107(211km) with positively result! Thank you Alimech!

Great video! Thanks for your work!

Nice work! 👍🏻

Cheap harbor freight walnut blasters along with my small air compressor works perfect every time. From tear down to back up and running again only takes me about 3 hours. Using walnuts to blast carbon creates perfectly clean, brand new looking valve stems and cylinder head. Plus you don't get the gunky mess you get with chemical cleaning.

I ended up trying to clean carbon off the intake valves on my 74 MGB and had minimal success with any trick until I ended up trying a can of Liqui Moly valve clean. I soaked the valves overnight with the head at an angle and the next day it flaked off like it was dandruff. Liqui Moly valve clean is the best product I tried yet, and it works best in the gas tank. Use it occasionally and your valves and pistons will remain carbon free.

Great results. SUBSCRIBED

Hello, you have closed the first valve, maybe the first and fourth are closed, and the second and third remain open. Shall we repeat once again closing the second and third valves, or not? If this cleaner is not available with wd40, can I use Ice Diclo instead? Greetings

Really good job and amazing results. Unfortunately it's necessary for a most of new engines with direct fuel injection (gasoline). Sometimes it mandatory for diesel due to EGR works. Thanks for sharing your knowledge and I wish you all the best in New Year.

Great video, thanks!

Nice information, thanx bro 🙏

Love from morocoo my friend ❤ merry Christmas.

Do you have a link for the yellow shop towels? Never seen them before!

Good video and information 👍👍

Awesome Video 🤘🏽

Ballin! I wish you would have done some diagnostics or did an average of mpg per tank. I bet that helped a lot more than just head performance

Nice work 👍

Excelente excelente hermano ésto lo tengo que hacer yo también. Te felicito.

How is silinder on outlander sport, any same?

You are the best!

Absolutely brilliant 😁 I will try brother but I have a 2007 Toyota Prius hybrid Will need to take out

Lovely work

Thank you Ali. Wishes from India.

Great info...❤️❤️

what's the real impact of carbon removal on performance / compression / other ? from my side the only important part that should be clean is valve seat that cannot really be cleaned that way. is there any risk of damaging cylinders wall with introdution of lot of "shit" in the combustion chamber or do you manually rotate the engine to close valve beafore cleaning ?

Nice job🔥💯

How do we know which cylinder is in open position and which one is in close position after we remove the intake manifold? 2018 Corolla LE.

does the type of metal of the engine head determine which chemicals you can use? Also do you think that engine decarbonisation does a similar thing, I know there is no physical contact there only a chemical reaction (I'm also gonna check and see if this is explained the other vid you linked with no contact cleaning)

Thanks. What mileage was your car when you provided that procedure???

Subscribed! 🙋‍♂️🙋‍♂️

very good, here in Brazil we use alcohol fuel in flex-fuel cars, with two alcohol tanks the effect is very good, both for intake and exhaust.

This is a great video

Tell me sir oil catch can is safe or not some people is say's engine damage oil catch can tell me plz

What about contact surface that’s what matters the most keeps them seated right.

You add water inside with open valves?

Great video. But I’m wondering, obviously one of the cylinders is going to be in the intake stroke and the intake valve will be open. All that cleaner is going to go inside the cylinder. How did you manage that so the car will start again since the cylinder may have a lot cleaner in it? Thanks.

I use oven degrease product to soap n clean all that gunk out from intake manifold, works great!!!

Keep watching and support especially 45sec. Ads from Al Khafji Saudi Arabia 👍

A sand blaster from HarborFreight is like 10 bucks, some fine walnut media is like 25 bucks also from HarborFreight so for 40 bucks you can do it the way professionals do it and it is so much faster when you do walnut blasting then using chemicals and a brush. To top it off in the long run it’s cheaper using walnut you can do probably 20 four cylinder engines with the one box of walnut, when using chemicals it’s way more expensive plus it takes longer. Also some chemicals can swell the valve seals which will cause the valve seals to start leaking, obviously the chemicals aren’t in direct contact with the valve seals but you are using compressed air and the chemicals are on the valve stem so some will work it’s way up the stem. Anyways if you clean the valves up nice all you need to do to keep them clean is use a cleaner every 15k miles or once a year you want a chemical that sprays a light mist through the intake over a good 30-45 minutes I have a pressurized fuel injection kit that runs off compressed air and I have an attachment that sprays a very fine mist it’s so fine it’s almost like a fog and it run it before the throttle body I run it at a lowest pressure I can to where it’s still a very nice mist so it lasts as long as possible usually 30 mins or more and if u use a quality chemical it will clean the carbon deposits off the intake valve and the intake runner, if u do this every 15k or every year after the valves are clean it will keep them clean so u don’t need to do pull the intake to clean the valves. You can actually buy a pressurized fuel injection cleaning kit that comes with the same mist attachment that I’m talking about for 50-100 bucks on eBay. The kit I have is much more expensive but I use it every day and I’m sure the cheap ebay kit will work just fine for someone to use at home. If u have direct injection buy one of the kits and keep ur valves clean before you have a problem.

Can we oil the cylinder after this procedure? To make walls lubricated for extra care ? Oiling through spark holes

Getting ready to do this on my PT Cruiser. It looks the same. Getting ready to buy some brushes. I won't use wire brushes. I'm not sure if there is a position that has all the valves closed at once. I need to figure that out.

Some people use ac delco foam for cleaning and that cause engine problem...there is a new material for this from bluechem group...called k1 and k2

Hey bro i like ur videos i have dropped some depris while im removing the intake manifold what should i do how to remove the junk ? Any idea

Hi ali, can you please make a video regarding automatic transmissions diagnosing and repairs, specifically with the solenoid valves. Thanks in advance

Can you share the link to the video about installing the oil catch can

Very good job

How to turn the engine with a started to close the valves? Should we disconnect fuel pump and remove plugs or coils?

I can feel my Hyundai accent needs this bad since it’s got a gdi engine. I’m gonna try this and clean the catalytic converters. Also how do you know which pistons are up and which are down?

Great job, but how did you bring out the diary out from the inside the engine, please

Interesting video, out of interest how many miles on this engine please?

Very helpful

Very nice

hi, after using the wd40, what did you use for cleaning the valve, im sorry im french so i dont understand very well. in the video i heard carp cleaner ? but it's injector cleaner right ?

My friend had a intake valve carbon buildup in his v6 ranger , Ford couldn't find out why yhe engine was bucking, took it to an old mechanic who made him run his engine until it was hot , he then proceeded to pour ice cold water in the intake with the engine at high rpms, it literally destroyed the carbon build up and it ran like new afterwards

Good job

Good afternoon, please tell me the link to the towels that you use.

wow..i must try

Can I do that in a chrysler 300?

can be cleaned with a brass or bronze brush?

I love to try it but little scary... What if i do wrongly ?

Is it ok, if the alternator gets wet?

Why dont you use Carbon x k1 k2???

How to know that which cylinder is closed

Please guide me how make inhone degreaser at home which gave me better result

I'm thinking of doing this, but I don't have air compressor. Maybe, a compressed air in a can will work.

You cleaned the tops and stems of the valves but since they are in the closed position what about the valve seal points in the seat? How are those cleaned? Do they need to be cleaned as well?

ЕГР туда грязь загоняет или система вентиляции картера?

Too much work for my Lexus IS250. Takes too much effort to remove my intake manifold... :( But as always, GREAT VIDEO!

Non-chlorinated brake cleaner is okay to get into the piston chamber. Most of it will evaporate and the rest will burn out. Should you clear a lot of carbon then pull the fuel pump fuse, pull the spark plugs and crank the motor. It will spit out the stuff in the piston. Do not use brake cleaner on vinyl or neoprene gaskets like on throttle body. Chlorinated brake cleaner can damage piston rings.

idk if im just not smart. but how do i open and close the intake valves 😭

Please, how do you turn the engine?

how many miles before they clean intake valve?

دەستەکانت خۆش بێت

You are cleaning the outside the engine in the way out 😄

What if valve seals are worn? Not a good idea to do this I suppose?

oil catch can?

Is for diesel engines?

With the kit i use i save money because you have to charge extra to remove the intake. I'm done in 15 minutes and give a before and after with my bore scope to the customer. And it's 75 for gas 125 for diesel.

I should bring my car to you and pay for yoyr service. 👍 Seriously...if in the U.S.

Man! I really wanted to see how that looked after using the drill!

How do you find out if your car has direct or indirect

You would never want to sand blast it , nut shells blast and your done carb spray doesn't work most times

يعني حمامك سعادة اجت دورة انا❤

That’s ballsy 😂

Makes me wonder how well oven cleaner would work. It's been removing carboned cheese for years.

If engine burns bad and the carbon is hardened you’ll have to take the valves off and scrape that shit with something hard. I tried looooads of chemicals and nothing worked, the only tool that did the job was a cutter blade and it took many hours.

CRC Intake Valve cleaner will work 1000% better than those other 2 cans lol

Valve seals get damage for the chemicals youre using, not recommended... wallnuts blasting is the way to go for..

A can of oven cleaner works a treat, get the foam one

Brother Replacing the oil-changing cap will eliminate this problem.

Catch cans doesn't prevent carbon build up....

Pressure wash on the alternator gave me the 🙈🙉🙊

WD40 is NOT a penetrating substance; it is a WATER DISPLACEMENT solution, thus the acronym "WD" meaning Water Displacement.
