@@DIYAutoworksNGdid you do the one hour heat soak after spraying it? On every other video they let it set and soak into the carbon for a hour before driving it at highway speeds? I guess that is what allows the cleaner to soak into the carbon?
Just a thought about your before/after… most valves rotate slightly every time the cam shaft engages as part of the design to allow for even wear. So it’s possible on the one valve that actually got worse, you were just seeing a different face of it. Thanks for the video!
I've used it 4 times so far and I've noticed some difference, engine was quieter and the car was more responsive. Surprised it didn't clean anything, but I'm looking forward for you to test more intake spray products like this.
@@DIYAutoworksNGdo you think bringing it all the way up to operating temp would help? Seems getting the carbon as warm as possible may help loosen it.
@@DIYAutoworksNGI've watched multiple people do this and the ones who have success are using crc but the main thing is the 1 hour heat soak. They spray it in then shut the car off and let it soak into the carbon for a full hour. Then they take it out and drive for 10 min at highway speeds.
First you walnut blast it, then you use liquid moly to prevent it from coming back. It will get small build up off, it just can get large build up off...
And that's been my findings, glad to see an honest review, last test I did used 6 cans on my diesel Pajero, the end result showed almost zero , a far better and logical approach is to close up your service intervals and ad a quality catch can, far more effective.
Very good video - nice comparison of the valves before and after. That leads me to think, that the only proper solution is mechanical cleaning of the valves.
Hello, thanks for all you do with your videos, please do you have the video for the mechanical cleaning of the valves, I went through your channel, it seems I did not see it, please help with a link to the video, thank you and continue to educate us about our cars.
I used throttle body cleaner from mannol. I removed the intake plenum, made sure the intake valve on the cylinder was closed and filled the gummed up port with throttle body cleaner. After 1-2 minutes I started scrubbing with a nylon brush and soaked a couple of paper towels with this ugly mess. Now repeat 2-3x and you’ll have shiny new factory intake ports. Compressed air will help a bit. Costs are like $20 for a whole engine and plan around 20-30 minutes per cylinder.
Hey man, love your videos as always. I just wanted to comment that you might be seeing the other sides of the valve stem, as they are designed to rotate in operation, just my opinion, maybe it's not in this case. Happy new year.
Yep. CRC intake cleaner did a better job. I had to rewatch my video on that to verify. Yet to test it through throttle body injection. My prior experiences were through the brake booster line, but someone said it does better through the throttle body.
great video! this product is good. product that cleans those areas in slow way is better for the engine so it dont harm the engine or the catalyst converter. so the solution to make it clean with time is to keep using the product regularly every oil change. these new engine with all environment systems need this product. also it's very recommended to use catalyst converter cleaner (add to fuel version) after using this product to clean catalyst converter from deposits came from engine components
For the valve cleaner you did 5 rounds with the liquid moly in the tanks of petrol... one could draw the conclusion... that perhaps you need another few goes....AND try to clean them the way you tried with the other product (CRC - through the brake line booster?)
Interesting take. I still have one can left which I intend to use too. The instructions don't say to use it any other way, but I'll do some more digging about that use through the brake booster line. Thanks for suggesting!
Is this the car you used the valve cleaner in the fuel where you aftet a few cans and italian tune ups , cleaned it up...this car is very dirty and would you say really needs way more help?.hiw many miles does this one have and what kind of gas was used..also id it only city driving.
@@DIYAutoworksNG wasnt it a lot cleaner though after the fuel treatments and how many miles has it been since then? Also do you regularly use a cleaner in your fill ups since the gas is crap? And is it mainly city driving?
I just got a cleaner which can be dispensed in aliquots into each fill up. Plan is to add it with every fill up. Video will come here too. It's mixed driving, maybe 50/50.
Hello, how are you . I am a big fan of what you do. I have an im 508 device and I have two keys and I want to know how I can find out the frequency of the two keys from this device . Thank you 😊😊
Hey. Thanks for the compliment. Did your 508 come with the XP400Pro? If yes, that's what you'll use. It'll be best to see the manual for specific steps.
I own a Mazdaspeed 3 and they have the same problem, theres a company "Corksport" that have a kit, so that you can sandblast.the valves, and BMW has a service for that too.... i think its the only way
Hi, nice video like all videos, but this product is not specialy for cleaning the valves, but for cleaning the throttle valve and product intended for cleaning valves is Liqui Moly Pro Line Intake System Cleaner, but this product is only for Diesel.
It's the use of ground walnut shell media through special equipment that knocks off the carbon and sucks it up. Disassembly is required to perform that procedure.
You have use another way to send liquid to the valve throttle body will not access your cylinder valve needed to find a map sensor and and insert the liquid
Direct Injection was a stupid idea & there fix was to add more injector that sometimes spray over the values to keep them clean. Sure you get more power with direct but building engines for everyday cars with di is so dumb.
Believe me, I feel that frustration. That said, I won't totally call it dumb, I think car makers should do it the way Toyota does it; the dual injection way. Best of both worlds.
Liqui Moly is good, but its not that good. It might be worth trying a can of that once mechanical cleaning has been done to prevent mechanical cleaning again.
Another win for mechanical cleaning.
😂 I Plan to test a few more before I go mechanical 😅
I love your honesty and watch all your videos bro. Great stuff.
Thanks you for taking the time to comment!
@@DIYAutoworksNGhave you tried the CRC intake cleaner? It's supposed made specifically for gdi engines.
Yep. I have a video on that too on the channel. Comparing the 2 products, CRC did a better job.
@@DIYAutoworksNGdid you do the one hour heat soak after spraying it? On every other video they let it set and soak into the carbon for a hour before driving it at highway speeds? I guess that is what allows the cleaner to soak into the carbon?

Great video bredren. Been watching a few this week and finally subbed.
Welcome aboard! Much appreciated!

In all honesty, car feels more responsive actually and it idles better. My fuel trims are now also close to 0!. Will test more😂
@@DIYAutoworksNG I very much hope so you can do more tests
@@DIYAutoworksNGdo you think bringing it all the way up to operating temp would help? Seems getting the carbon as warm as possible may help loosen it.
Every cleaner I know out there seems to like heat, so I just went with the flow 🤣
@@DIYAutoworksNGI've watched multiple people do this and the ones who have success are using crc but the main thing is the 1 hour heat soak. They spray it in then shut the car off and let it soak into the carbon for a full hour. Then they take it out and drive for 10 min at highway speeds.
All of these products appear to be a waste of money. Thank you for bringing this to my attention.
Not all but the majority, for exemple liqui moly's engine flush do work great
I agree
He showed that 6 cans of LM Valve cleaner brought the cylinders back to new...along with 1900 miles of spirited driving.
First you walnut blast it, then you use liquid moly to prevent it from coming back. It will get small build up off, it just can get large build up off...
I own a diesel. I used WD40 and denatured alcohol with a brush mounted to a drill. The results were well worth the effort.
I'll be doing that drill approach soon!
And that's been my findings, glad to see an honest review, last test I did used 6 cans on my diesel Pajero, the end result showed almost zero , a far better and logical approach is to close up your service intervals and ad a quality catch can, far more effective.
Wow! 6 cans, you definitely gave it all the opportunity to work. CRC intake and turbo cleaner did better.
Very good video - nice comparison of the valves before and after. That leads me to think, that the only proper solution is mechanical cleaning of the valves.
Seeming so when they're this gunked up. I'll be repeated CRC intake valve cleaner 2 weeks apart and will post the video too!
This one actually works better than expected
Emmm. I expected more though...
@ the key is the soak wait time

Many thanks for this comment. Didn't consider the spinning! Happy New Year too. Thanks again for the support.
Would it make sense to do this procedure with every oil change since the car is brand new...? Would that keep the carbon off the valves...??
Good video bro, thank you for your good job!
You're welcome
Great video, but I believe CRC's intake valve and turbo cleaner does a superior job particularly on GDI's.

Great content bro
Appreciate it!
Driving longer distance very fast with high temperature can help a lot
Very true! Usually. But I'm not sure with this product, particularly for the intake valves.
4:15
Which app is that?
thanks for the video so i see i brings nothing i want to do it on my bmw e90 lci n53 but now i will sont buy it.

You points are spot on! More gentle cleaning will be easy on the CAT.

Same car. Gas quality is not the best. Premium gas is not available. But then, it's GDI, so those are expected of the intake valves...

Can this stuff used to clean O2 sensors?
It's not advertised as so. Didn't test.
There is a procedure using walnut shells? to blast the carbon away .
Yep. It's not readily available though, so I opted to experiment with some cleaners and report on effectiveness.
need to test Xenum product is good ;) DPF cleaner for catalytic
Thanks for suggesting
Scotty said yes
As you could see, I'm only sharing what I found from my own experience
These cleaners would work best as a preventative after a good manual cleaning.
A good point, though we still need hard-line cleaners especially in the case of getting used cars.
Did U try the valve cleaner via a spray bottle on the intake ??
Nope. That could be interesting.
I own a Mazdaspeed 3 and they have the same problem, theres a company "Corksport" that have a kit, so that you can sandblast.the valves, and BMW has a service for that too.... i think its the only way
You need it walnut blasted first and then you use the liquid Moly once every 2 weeks to prevent it from coming back....
I agree that walnut blasting will make this sparkle, but using this product once every 2 weeks will be too much of an ask.
Is this 1.5 litre turbo charge gdi or 2.0 litre. Turbo gdi.? I hear theres head gasket issues from this engine or the newer ones.
no, its 2.4 NA
2.4L. No turbo.
Did you let the cleaner heat soak?
The product directions doesn't say to heat soak. Also it's quite volatile and evaporates quickly
Nice video help me to choose the rigth video
Glad to hear that
For heavily deposited valve like shown, petroleum distillate chemistry ain't gonna cut it. Thanks.
Walnut blast (mechanical cleaning)
I have a few plans after which I'd do mechanical cleaning when I take off the fuel injectors.
Hi, nice video like all videos, but this product is not specialy for cleaning the valves, but for cleaning the throttle valve and product intended for cleaning valves is Liqui Moly Pro Line Intake System Cleaner, but this product is only for Diesel.
But this says on the tin that it "reliably cleans intake valves"...
@@DIYAutoworksNG Yes, i know but you can see on video, very small difference on the valves with this product.
Agree. Little to no difference.
Have you tried seafoam?
Not yet
@@DIYAutoworksNG that will be interesting specially from you
Drosselklappe means only throttle body not everything else that you try to clean
Thanks for the translation, but the fineprint, says it cleans intake valves too.
Didn't catch that, but highly doubt. Carbon build is hard to remove only with additive, needs to be mechanical
Good videos. I'm American. What language are you speaking? I had to use the closed captioning. Just kidding. Excellent documentation of the results.
😂😆😆
Thanks!
thanks for the video. what is the best way to clean them?
Walnut blasting, but not easily accessible depending on where you live.
@@DIYAutoworksNG what is walnut blasting??!
It's the use of ground walnut shell media through special equipment that knocks off the carbon and sucks it up. Disassembly is required to perform that procedure.
@@DIYAutoworksNG thanks
You have use another way to send liquid to the valve throttle body will not access your cylinder valve needed to find a map sensor and and insert the liquid
The method used in the video is what is recommended on the product.
You probably have to drive a few hundred kilometres to see any effect. Just 1-3 spirited drives probably wouldn't do the job.
Well, you have a point. If I use it again, I'll do some extended driving.
@@DIYAutoworksNG just dont waste your time, carbon needs to be cleaned out manualy at this point.
Can you do a video on CRC turbo/intake cleaner ?
Hi. Thanks for watching. Already used the CRC too. Here's that video ua-cam.com/video/Czb6_xwkmYY/v-deo.html
Direct Injection was a stupid idea & there fix was to add more injector that sometimes spray over the values to keep them clean. Sure you get more power with direct but building engines for everyday cars with di is so dumb.
Believe me, I feel that frustration. That said, I won't totally call it dumb, I think car makers should do it the way Toyota does it; the dual injection way. Best of both worlds.
It is much better to use Cleaner for the Gasoline inside the Tank. That cleans much better.
Won't reach the back of the valves on a GDI engine.
Brother. I just entered your channel. And you are soo impressive and full of knowledge. Like. Share and subscribe directly
Thank you!
Not very successful 😬 walnut blasting will do the trick but its a lot more involved and expensive.
👍
Honda the power of screams 😂
😅🤣
It's tells one thing, stay away from GDI eangen. Cost to much for maintenance.
Lol. I feel you. Dual injection is the best of both worlds.
Yet more evidence that the 'mechanic in a can' is more myth than reality.
People don't fit in cans. 😂
Hiç bi bka yarımıyor
WD40 tut es auch
Kostet halt 5x weniger
I've heard that too for mechanical cleaning. Are you suggesting using WD-40 through a vaccum line with the engine working?
Don't be deceived by the german farts😂
"click" Noice
You need to soak it
Joke product! Waste of money! Try automatic transmission fluid!
If you don't try, you won't know. Right?
They all are a waste if money
Not all. CRC intake cleaner did a much better job when I tested it.
O carro tá podre....e você quer mesmo resolver com produtos?
Ahhh aí não né 😜
Liqui Moly is good, but its not that good. It might be worth trying a can of that once mechanical cleaning has been done to prevent mechanical cleaning again.
I agree
